Abstract
This paper presents the experimental results of composite rebars based on GFRP and CFRP manufactured by a pultrusion system. The off-plane compression strength of rods was determined. This compression test reflects the weakest nature of the composite materials based on the interlaminar compressive strength. The proposed methodology allows us to invariantly describe the experimental transversal strength of the composite materials. As a result, the force–displacement graphs were plotted. The experimental results are compared with computational results using the Finite Element Method. In off-plane compression the matrix carries the load, all the specimens regardless of the length were cracked in the same way, in the middle of the cross-section. It is worth noting that the failure and fracture mechanism plays a crucial role as a material quality indicator in the manufacturing process. The comparison showed differences between the experiment and the FEM results that may come from the imperfection in the structure.
