Abstract: Carbon fibre reinforced aluminium matrix (CF/Al) composites were fabricated with a hybridization technology through pressure casting and characterization of the hybrid composites obtained was carried out. Hybridization with SiC additive could improve the infiltration performance of fibre preform, control the fibre volume fraction, and increase the fibre-strength transfer efficiency of the hybrid composites. The longitudinal tensile strength of the hybrid composites was greatly improved compared with that of the conventional composite. It was found that the strength deterioration of high-modulus cab on fibres (HMCFs) during fabrication was not heavy and depended upon the type of aluminium matrix, while the strength of high-strength carbon fibres (HSCFs) was greatly reduced by aluminium matrix, but the degradation did not depend on the variety of the matrix. As a result, the longitudinal tensile strength of hybrid HMCF/Al composites was higher than 800 MPa, while that of hybrid HSCF/Al composites was about 400 MPa. Contrariwise, the transverse tensile strength of hybrid HSCF/Al composites was much greater than that of hybrid HMCF/Al composites. The results of thermal exposure of hybrid HMCF/Al-Si composites at 773 K showed that their longitudinal tensile strength increased, then decreased, while their transverse tensile strength increased montonically, as the exposure was proceeded. The thermal exposure slightly reduced fibre strength, caused chemical interactions, and resulted in changes of fracture morphology and fibre pull-out length of the composites. It was also concluded that fibre/matrix interfacial bonding has an important effect on the mechanical properties of CF/Al composites and intermediate interfacial bonding can be expected to result in good longitudinal and transverse tensile strengths of CF/Al composites.
