| 摘 要： | 本文在细观力学模型的基础上,考虑到缠绕工艺,提出一种计算缠绕复合材料三维弹性模量的方法。该方法将代表单元分为层合部分和编织部分。层合部分用经典层合板理论计算刚度矩阵,编织部分采用四胞模型和均一化方法计算刚度矩阵,最后按两部分在代表单元中所占比例,将两部分的刚度矩阵平均化,得到代表单元的刚度矩阵。利用该方法预测了几种材料的弹性模量,并与实验结果对比,结果显示本文所提出的方法能较好地计算缠绕复合材料的弹性模量。

| Abstract: | Based on the analysis of the 3D micromechanical model and the characteristics of winding pattern,a new method was presented to calculate the elastic modulus of filament winding composites.The method was that a representative filament winding pattern was divided into a laminate field and a woven fabric field.The two fields' elastic moduli were calculated,respectively.For the laminate field,classical laminate theory can be used to calculate its elastic modulus.For woven fabric field,micromechanical approach a... |
