摘要

摘要: 剪切强度和剪切韧性是反映复合材料构件在复合受力状态下承载能力及耗能能力的重要指标，不同铺层方式的单向玻璃纤维与短切玻璃纤维混杂增强复合材料层合板的层间剪切性能有明显差异。文中基于HyperWorks 商用有限元软件建立了精确的复合材料层合板模型，通过数值模拟分析不同铺层方式复合材料层合板的层间剪切性能。研究结果表明，铺层材料对复合材料层合板的层间剪切性能影响较大，而铺层顺序对复合材料层合板的层间剪切性能影响较小。

Abstract: Shear strength and shear toughness are important indexes to reflect the bearing capacity and energy dissipation capacity of composite components under complex stress condition. The interlaminar shear properties of composite laminates reinforced by unidirectional glass fiber and short-cut glass fiber hybrid with different laminate methods are significantly different. Based on the HyperWorks commercial finite element software, an accurate composite laminate model is established and the interlaminar shear properties of composite laminates with different laminate modes are numerically analyzed in this paper. The results show that the interlaminar shear strength of the composite laminates is greatly affected by the lay-up materials but less affected by the lay-up sequence.
