  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 )

    本研究以武裝直升護裝甲材料為研究對象,採用真熱壓粉末冶金燒結工藝制備了含sic顆粒體積分數分別為5 、 15和25的sic顆粒增強鋁基復合材料,結合其力學性能、掃描電鏡和界面微能譜分析結果,分析了sic _ p al復合材料的真燒結過程中的界面現象,以及材料增強和斷裂理,並利用hopkinson高速壓桿沖擊實驗系統對其從靜態到動態(應變率為3 . 3 10 ~ ( - 3 ) s ~ ( - 1 ) 5 . 2 10 ~ 3s ~ ( - 1 ) )的壓縮破壞響應進行了研究,分析了不同體積分數sic _ p al復合材料高應變率壓縮載荷下,材料的變形和微觀損傷理,以及利用高速沖擊氣炮測定了改復合材料制備剃度復合板的穿透性能。
