Tensile properties of carbon fiber/polyester hybrid 3-D woven composite plates

In order to obtain the relationship between fiber volume fraction and tensile fracture of carbon fiber /polyester hybrid fiber reinforced plastics(HFRP),five kinds of yarns were designed through varying the mixed ratio,and the tensile property of the resulting composites was studied.The results indicated that there is a close relationship between stretching-breaking process and tensile strength of the fiber content of reinforced fibes.The elongation at break of HFRP increased as the content of polyester increases.The tensile strength and tensile elasticity modulus show a cubic equation relationship with the percentage content of polyester.There is an obviously hybrid effect for the sample′s tensile strength and tensile elasticity modulus.
