分层缺陷深度对复合材料层合板力学性能的影响
Effect of delamination defects depth on mechanical properties of composite laminates
摘 要
通过对含分层缺陷的复合材料层合板进行压缩、弯曲以及拉伸试验,研究了分层缺陷深度对层合板力学性能的影响;对影响层合板力学性能的因素进行定性分析,得到了层合板力学性能随分层缺陷深度的变化规律。结果表明:分层缺陷深度对层合板的抗压、抗弯强度有直接影响,而对抗拉强度的影响十分有限。

Abstract
Through the compression, bending and tensile tests of composite laminates with delamination defects, the influence of the depth of delamination defects on the mechanical properties of the laminates was studied. The factors affecting the mechanical properties of the laminates were qualitatively analyzed, and the variation law of the mechanical properties of the laminates with the depth of delamination defects was obtained. The results show that the depth of delamination defects had a direct effect on the compressive and bending strength of laminates, but had a limited effect on the tensile strength.
