It is found that the great cracks on the coarse surface are initiated easily than on the smooth surface by the sem observation and the crack size obtained at the dynamic indentation experiment is bigger than at the static indentation experiment under the same load. it is showed the single crystal silicon is easier to initiate the crack and fracture under dynamic load, the single crystal silicon ’ s
然後通過sem觀察單晶硅試件表面壓痕形貌，發現粗糙表面比光滑表面容易生成大裂紋，在相同載荷作用下單晶硅材料在動態壓痕試驗得到的裂紋要大於在靜態壓痕試驗得到的裂紋，表明在動態加載條件下單晶硅材料更容易生成裂紋和破碎。 -
Therefore, interlayer toughened composites are the excellent candidate materials for primary structure of aircrafts. in this paper, composites modified with particle - interlayer were fabricated. based on the aims of improving compression strength after impact ( cai ) and evaluate damage resistance and damage tolerance, mode ii fracture toughness test and quasi - static indentation test ( qsi ) were conducted
本文採用層間顆粒增韌技術制備試驗件，基於提高沖擊后壓縮強度（ cai ）和考察損傷阻抗、損傷容限的目的，試驗測試了型層間斷裂韌性g _ （ c ） 、準靜壓痕（ qsi ）試驗的分層起始能量和接觸力?凹坑深度關系。
