碳纤维复合材料层板在准静态球头压入条件下的压入深度-压力-电阻性质

摘要

在ASTM D6264-98试验方法的基础上，同步测量了碳纤维复合材料层板的压入深度-压力-电阻、以及电阻-时间关系，确定了电极形式对这些关系的影响规律，拓展了ASTM D6264-98试验方法的探测范围和探测量，为准静态压入方法研究材料损伤创造了有利的试验条件。%In accordance with ASTM D6264-98 test method, the indenter depth-contact force-resistance relation and the resistance-time relation of epoxy based carbon fiber laminates were simultaneously measured with respect to the variation of electrodes. The investigation explored and expanded the ASTM standard, made a simultaneous detect of concentrated indentation-induced damage of composite laminates possible.
