1. Introduction

Today, individuals are becoming more conscious of the ecological issues and their problems that are spoiling against the material than at any other time. Legislative strategies are compelling enterprises and organizations to discover sustainable assets to supplant conventional ones [1]. This has driven us ever nearer to regular resources and their use. Be that as it may, while the interest for environmental mindful applications is expanding, the worry about the shortage and availability of natural resources is increased. Simultaneously, the development of population, rising urbanization, and better expectations of living create increasingly more waste constantly. This waste likewise incorporates bio-based materials that could be additionally used.

This is the reason why scientists and industries are concentrating on discovering better approaches to use bio-based waste streams to create value-added inexhaustible and feasible product solutions for supplanting traditional ones. While considering the most all-inclusive plentiful, exceptional and cheap waste streams which could be used for esteem include applications, one can't pass the poultry. The waste in the poultry industry comprises of quills, inward organs, blood, bones, skin, feet, and leftover meat. Out of these co products, particularly, poultry quills [2] have pulled in intrigue. It has been anticipated that in 2017, just the broiler meat creation will be 89.5 million tons around the world (USDA, 2017). On the off chance that it is, at that point accepted that the poultry business squander covers 30% of its all-out weight and chicken feather establish around 10% of chicken’s [3, 4] weight, the chicken quill waste can be thought to be 12 million tons around the world. At the same time sawdust also a major problem in our environment, because of furniture in home doors windows and so many things we make with trees, without trees we are losing so much at the same time this dust will not soluble. So, we have to stop cutting trees and re-use the dust in other purpose which will not spoil nature. So, two different fibers are considered in this work.

The Five varieties of composite specimens are considered to study the progression of fiber-matrix adhesion using a hand layup method [5]. The Ampeg 21 epoxy resin was used as a matrix for glass fiber-epoxy resin and E-Glass fiber was used for matrix reinforcement. Here Morphology and the XRD methods are examined. In the morphology the fractured structure and in EDS the elemental composition observed. In the XRD process the results show the Bragg’s angle θ=20.6o, the crystalline structure is silica in the composite. So, this composite is projected that it gives, better dimensional stability and high-performance structural applications.

The composite materials made up of natural resources are more frequently used, as they are low-cost and less weight which was emphasized in this work [6]. The study of polymer composite of polyvinyl chloride (PVC) using palm fibers at different loadings such as 10% and 30% by weight. Using a chemical modification of date palm fibers between matrix-filler interfaces, considering two types of testing’s alkali, acetylation. By examining the ratios using morphological, thermal, and mechanical and Water absorption properties of composites give fewer properties and water absorption.

The aeronautic trade centered around the framework Ti-TiAl-BuC, which has decent relations between the properties and microstructure, as far as the procedure parameters of the titanium and matrix composite [7]. The powder metallurgy method was utilized the TMCs which can manufacture the inductive hot squeezing, it offers the adaptability and flexibility. The short handling time utilized (5min) was set to test the temperature as a central point to impact in the secondary relations. Concerning preparing conditions, the higher the weight, the more substance of TiB and TiC at comparative handling temperature, paying little mind to the starting powder.

The composite materials which are based on Polytetrafluoroethylene studies on the X-Ray structure of amorphous-crystalline which were performed at high-temperature heating [8]. The thermal stability limits of the structures of composites were determined and the crystalline and amorphous components of the composite matrices of temperature dependencies of the parameters were determined and examined.

Right now, it was extricated from the expendable chicken feather utilizing l-cysteine as a lessening agent [9]. At that point, it was re-disintegrated in the sodium carbonate-sodium bicarbonate support, and the pure keratin membrane and fiber were manufactured by specialist cutting edge throwing procedure and wet spinning process, individually. SEM, FT-IR spectroscopy, XRD, and TGA were utilized to describe the chemical and physical properties of coming about powder, membrane, and fiber.

SnCl4/nano-sawdust was set up as a starch-based impetus containing of tin bearing cellulose units [10]. The impetus was described by XRD, FT-IR, FESEM, and EDS. The impetus was applied effectively as a promptly accessible, reasonable, biodegradable, and naturally favorable heterogeneous bio-based strong corrosive for the one-pot amalgamation of 2-subbed benzimidazoles and benzothiazoles.

The characterization and preparation of magnetite-carboxymethyl cellulose nano-composite (M-CMC) material is depicted [11]. Magnetite nanoparticles were incorporated by an altered co-precipitation strategy utilizing ferrous chloride tetrahydrate and ferric chloride hexahydrate in ammonium hydroxide arrangement. The biocompatible Fe3O4-carboxymethyl cellulose nanocomposite particles acquired from the normal CMC polymers have a potential scope of use in the biomedical field.

The seven different ratios have been prepared and three variety of testings such as FESEM, EDAX and XRD performed on all the ratios to find the micro structure and compositions in this work.

2. Materials and Methods

2.1 Considered materials

In this work one matrix and two fibers are used. Those are HDPE Granules as a matrix, neem sawdust, and chicken feather rachis as fibers. In HDPE Granules there are so many different types of grades available, out of which HD50MA180 is considered as matrix. This grade is useful for high strength injection molding products and for thin wall molded products its melt flow index is good compared with other grades of granules, its mechanical properties, and thermal properties also very good. So, by comparing with other grades, this is the best one to improve the strength and flexibility this grade has to be considered. The only matrix cannot make the sample strong and flexible so for making stronger, a matrix needs fiber to become a composite material and here it is having two different types of fibers used which are reused to become a hybrid composite material.

Neem sawdust [12] is one of the fibre used which is collected from the timber mill when the neem logs are cutting down, that collected sawdust is not having some size and shape it is just a particle mixing all the parts of the tree except leaves. These particles are sent to a mixture machine to get a fine powder. After that let that powder dry in the oven at room temperature for 2-3 hrs. So that the powder gets completely dry having no moisture content in that neem sawdust. It is one of the flexible, strong fiber, which is having low-cost and more available for low-class people.

The second fibre considered is chicken feather rachis which is not used till now. It was collected from any farm and washed with hot water to remove the dust particles on that feather. After they are dried using a dryer or keep them in the oven for 3hrs to make them completely dry. Later the outer parts of a feather are removed and remains only the middle part of the feather which is called the rachis. By considering the low-cost and high strength this is considered as one of the fibers.

2.2 Testing methods

SEM was designed about 50 years prior, SEM [13, 14] is currently a full-grown strategy and is applied broadly in numerous logical applications. SEM is an amazing technique in the assessment of materials metallurgy. The FESEM [15, 16] (Field Emission Scanning Electron Microscope) is the latest update of SEM. In this FESEM the magnification of 10X to 300,000X with virtually unlimited depth of field, produce clearer less electrostatically distorted images with spatial resolution down to 1.5 nanometers three to six times better than SEM. This FESEM has done in PSG, Coimbatore, make ZEISS (USA), model: SIGMA with GEMINI COLUMN, Resolution 1.5 mm, in-lens detector, SE2 detector, BSD detector. In FESEM for each sample five images have considered at 20um, 10um, 2um, width WD=10mm, EHT=10.00kv, signal A2= SE2 magnification are 500X, 1.00KX, 2.50KX, 5.00KX, 10.00KX.

EDAX used to recognize the elemental material composition. The information produced by EDX [17, 18] analysis comprises of spectra indicating peaks compared to the elements making up the genuine composition of the test is analyzed. This detector is utilized to isolate the XRD characteristics of various elements into a vitality range, and EDS framework programming is utilized to investigate the energy spectrum to decide the wealth of explicit elements.

To know the energy-dispersive XRD analysis, EDXA is an expository procedure utilized for the essential investigation or chemical portrayal of a sample that depends on the connection between the sample and x-beam show. At the point when associated with SEM, EDXA can quickly perform a basic investigation on elemental analysis of various territories at the sample which can give data in regards to the sample composition. This is done in PSG, Coimbatore, make: BRUKER(GERMAN), model: Nano x flash detector, EDAX (elemental analysis), point scan, line scan, area scan, and elemental mapping.

XRD is a quick diagnostic procedure essentially utilized for face identification of a crystalline material and can give data on unit cell measurements.

This test is done in the Vignan University CoExAmmpc research lab on the machine Rigaku Miniflex 600, Rigaku Corporation, Japan. In XRD [19, 20] the scan range is from 3.0000-90.0000 deg, the scan speed is 10.0000deg/min, scan mode CONTINUOUS, scan step is 0.0200deg, scan axis is theta /2-Theta, the incident parallel slit is 5.0 deg, the incident slit is 1.250 deg, length limiting slit is 10.0mm, the filter is K-beta(x1), receiving parallel slit is 5.0 deg, X-Ray is 40 KV, 15 mA, the wavelength is cuka/1.541862A, Goniometer is Miniflex 300/600, the detector is sc-70, the element properties found in these samples are carbon and oxygen. In this the above matter is common for all the samples. We have to take the Theta/2-Theta(deg) with intensity.

3. Preparation of Sample Ratio

The seven different ratios have been prepared by two types of machines they are screw extruder machine and injection moulding machine to get the granules from the samples. The ratios prepared are 80H: 10CF:10SD; 80H: 5CF:15SD; 80H: 15CF:5SD; 80H: 20CF; 70H: 30CF; 80H: 20SD and 70H: 30SD. In screw extruder one by one ratio is pouring by preheating at temperature 170℃-120℃ and pour the material into the melt. Then wire shape material will come out from the die and it directly dips into the water which keeps the side of that machine. The melted material comes out from the machine will fell into that water to get cool in a fraction of seconds and by using a cutter machine, it will cut the sample wires in a granule shape and that will be collected in a bag to store. For all the ratios the process is the same, after collecting the sample, without forgetting the label name.

The next one is the injection moulding process, the granules used are made from the screw extruder machine. In the machine pour the granules that granules will melt in a moulding machine to occupy the shaper or die of the mould to get that shape we remove the sample from the mould to get the desired shape for that samples we conduct the following testing’s they are FESEM, EXAD, and XRD.

4. Results and Discussion

The composite material which is prepared with different ratios are subjected to examine the morphology characterization using FESEM, EDAX, and XRD.

4.1 FESEM (Field Emission Scanning Electron Microscope) results

The FESEM results with composition 80H: 15CF:5SD are as given in Figure 1.

In the sample 80H:15CF:5SD there are no cracks found but the upper surface is so smooth when we increase the magnification irregular surfaces are having more up and downs.

The FESEM results with composition 80H: 10CF:10SD are as given in Figure 2.

In sample 80H: 10CF:10SD the images considered in 30um, 20um, 10um, 2um with WD=10.3mm, and magnification are the same. In the sample the images are not smooth at any magnification it has gaps on the surface when we go inner surface of the sample the surface is not finished perfectly.

The FESEM results with composition 70H:30CF are as given in Figure 3.

In sample 70H:30CF the images considered in 20um, the image is like lines not a smooth surface at magnification 500X when considering 1.00KX mag the surface image is not perfect and the surface is not smooth at 2um.

The FESEM results with composition 80H:20CF are as given in Figure 4.

In 80H:20CF the surface image is not smooth at 500x mag in 20um at 1.00KX mag the image is like wires placed on the surface at 20um. In mag 2.50kx at 10um the surface is smooth again in 5.00kx at 2um image the surface is not filled properly, in 10.00kx at 1um the image is irregular.

The FESEM results with composition 70H:30SD are as given in Figure 5.

In 70H:30SD the mag 500x at 20um is better when compared to the above sample image at this magnification. In other magnification also the surface images are better compared with the above sample. There are little cracks in this sample and some gaps found in 10.00kx at 3um.

The FESEM results with composition 80H:5CF:15SD are as given in Figure 6.

In 80H:5CF:15SD the images are very good at all magnifications compared to all the samples also because of the rachis the material has gathered at some places, if we spread those powder to all directions the image has done properly in FESEM.

It was observed from all the images of FESEM that the combination of HDPE and natural fibers like neem saw dust and chicken feather provides better surface smoothness, less irregularities and cracks.
