基于经典层合板理论(CLT),提出一个多参数解析模型,定量研究了面外波纹缺陷对含波纹缺陷的复合材料层合板弹性模量、剪切模量和泊松比等弹性性能的影响。结果表明:面外波纹对主弹性模量、Z向弹性模量、X-Z平面剪切模量和面内泊松比都产生了显著影响;对于碳纤维/环氧树脂材料体系算例,在特定波纹比和波纹区域范围内,面内泊松比出现了负值。该建模方法为研究波纹缺陷对复合材料层合板弹性性能影响提供了参考。 Based on CLT, a multiparameter analytical model was proposed to quantitatively study the effect of out-of-plane corrugation defects on the elastic properties such as modulus of elasticity, shear modulus and Poisson’s ratio of corrugated composites. The results show that the out-of-plane ripples have a significant effect on the main elastic modulus, Z-direction elastic modulus, XZ plane shear modulus and in-plane Poisson’s ratio. For the example of carbon fiber / epoxy resin system, The in-plane Poisson’s ratio shows a negative value in the ratio and ripple region. The modeling method provides a reference for studying the influence of corrugation defects on the elastic properties of composite laminates.
