Abstract: γ-mercaptopropyl trimethoxysilane (KH-590) powder was modified by silane coupling agent KH-590 and a series of cyanate ester resin composites containing the modified SiC were prepared.The effects of SiC content on the static mechanical properties,electrical insulation and friction properties of the composites were investigated.The cross-section morphology of the materials was observed by scanning electron microscope.The results shown that the introduction of a small amount of SiC powder can effectively improve the static mechanical properties and wear resistance of the cyanate ester composite,and the composite still maintained good electrical insulation properties.When the mass fraction of SiC was at 6%~8%,the impact strength and bending strength of the composites were increased by 89.6% and 67.6%,respectively,compared with pure cyanate ester resin (CE).When the mass fraction of SiC was 8%,the friction coefficient of the composite was 43.5% lower than that of pure CE,and the wear resistance of the composite was increased by 77.5% for pure CE.
