ASTM D7136/D7136M-15Standard Test Method for Measuring the Damage Resistance of a Fiber-Reinforced Polymer Matrix Composite to a Drop-Weight Impact Event

意义和用途对于由先进复合材料层压板制成的许多结构来说,对集中的平面外冲击力的损坏的敏感性是主要的设计问题之一。了解层压复合板的抗损坏性能对于产品开发和材料选择很有用。Drop-weight impact testing can serve the following purposes:定量确定堆叠顺序、纤维表面处理、纤维体积分数的变化以及加工和环境变量对特定复合材料层压板在集中落锤冲击力或能量下的抗损坏性的影响。To compare quantitatively the relative values of the damage resistance parameters for composite materials with different constituents.损伤响应参数可包括凹痕深度、损伤尺寸和全厚度位置、F1、Fmax、E1 和 Emax,以及力与时间曲线。To impart damage in a specimen for subsequent damage tolerance tests, such as Test Method D7137/D7137M.
