  1. Sicp / al matrix composites, with 5, 15 and 25 % volume fraction of sic particles, were prepared by vacuum hot - pressing sintering processing in this paper. based on mechanics properties, sem observation and energy dispersive x - ray analysis, the interface reaction phenomenon of sicp / al composites made by vacuum hot - pressing sintering, as well as the reinforcement and fracture mechanisms of this composite were analyzed. the dynamic responses of sipc / al composites were studied by a split hopkinson high - speed pressure bar impact system which strain rate was from quasistatic state strain rate ( 3. 3 10 - 3s - 1 ) to dynamic state strain rate ( 5. 2 103 s - 1 )
