Two kinds of prepreg and composites were prepared by CCF800H carbon fiber and AC631 bismaleimide resin.The properties of two composites were compared and discussed combining the results including micro morphology,feather amount of carbon fiber and fracture surface morphology of composite's 90° tensile strength.The results indicated that mechanical properties of AC631/CCF800H composites with 133g/m2 prepreg fiber mass,33wt% resin mass content (Type 2) were better than AC631/CCF800H composites with 145g/m2 prepreg fiber mass,35wt% resin mass content (Type 1).Compared with Type 1,0°unidirectional tensile strength,inter-laminar shear strength and compressive strength after impact of Type 2 were increased by 7.03%,9.09%,and 5.98% separately.The resin concentration area of Type 2 was smaller and the resin distribution was more uniform,which effectively improved the mechanical properties of the composites.
