Abstract:
In order to study the effect of interlayer hybrid type of unidirectional fiber on the mechanical properties and failure form of composites,the method of pultrusion process was adopted to prepare continuous unidirectional hybrid fiber reinforced epoxy composites with different interlaminar hybrid structure.The volume ratio of carbon fiber and glass fiber was 1:1 in the composites.The results show that the tensile strength of composites with interlaminar hybrid structure is between carbon fiber/epoxy composites and glass fiber/epoxy composites,and the tensile fracture mode is cleavage.The interlaminar shear strength of composites with interlaminar hybrid structure is better than carbon fiber/epoxy composites and glass fiber/epoxy composites,and the shear fracture mode is interlaminar fracture.
