摘要
提出了预测纺织结构复合材料弹性模量的理论方法，该法考虑了结构中实际存在的纬向纤维束和经向纤维束的曲屈对纺织结构复合材料弹性性能的影响，建立了复合材料弹性性能与织物结构参数——纬向和经向纤维束平均取向角之间的关系；并通过实验测试考察了以二维和三维织物制备的碳纤维织物／环氧树脂复合材料的弹性性能，将弹性模量的理论计算结果和实验数据相比较。
A model for predicting elastic property of textile structural composites is presented. Yarn undulation along both warp and weft directions is considered in the analysis. The relationship between composites elastic modulus and fabric structure parameters for 2 D and 3 D composites is created. The elastic properties of 2 D and 3 D carbon fabic/epoxy composites containing the same fibre volume fraction are examined experimentally. The experimental results coincide well with the theoretical predictions on the elastic moduli for 2 D and 3 D composites.
