THE EFFECTS OF SiC_P HYBRID ON THE PROPERTIES OF C/Al COMPOSITE MATERIALS FABRICATED BY VACUUM PRESSURE INFILTRATION

The carbon fiber reinforced aluminium composite material was fabricated by means of vacuum pressure infiltration to study the effects on the infiltration and on the properties of the SiC particles hybridized in carbon fibers.The tensile and bending properties were determined and the microstructure and fractography were investigated by the SEM.It was demonstrated that the SiC_P hybridized in fibers can separate the clustered fibers and prevent the contact of fibers to provide a better fiber distribution,which is beneficial to infiltration and composite material properties.Optimum properties have been shown in the material made up of sol-gel SiC coating fibers along with SiC_P hybridizing.
