| Abstract: | In order to solve the problems of traditional fiber reinforced thermoset plastics (FRP) for strengthening concrete structures,this paper suggests a thermoplastic for this usage. The moulding technique and the mechanical properties of the continuous Kevlar49 fiber reinforced thermoplastics (CFRTP) are studied. The results show that the mechanical properties of the CFRTP can compare with that existing FRPs.The scanning electron microscope (SEM) of fibers and composites shows that the rupture is not brittle, and there is an optimal ratio between fiber and resin. |
