This paper explores the process of fabricating truss bridge units from high-performance carbon fiber composite. The material, structure and manufacturing process of the units were confirmed through experimental research, and the bridge span of the truss composite structure was analyzed by numerical simulation. The results show that the truss bridge assembled by the carbon fiber composite truss, which was produced via vacuum-assisted integral molding, achieved a good overall performance, and was 38% lighter than steel truss bridge. The proposed process can be applied to set up lightweight highway bridges in an efficient manner for emergency rescue, disaster relief or traffic engineering.
