摘要

基于经纱矩形截面及纬纱双凸透镜截面假设

重点考虑了该结构表层经纱与内部经纱密度的不同及相同机织结构合成不同厚度和纤维束截面的情况

建立了2.5维机织复合材料的弹性性能预测模型.同时

试验测定了6种结构62个试件的弹性模量.数值预测与试验结果对比表明:研究建立的弹性性能预测模型可以较好地反映2.5维机织复合材料的内部结构;在2.5维机织复合材料弹性模量预测中

表层与内部经纱的差异不可忽略.

Abstract

Based on the hypothesis of rectangle and biconvex section shape of the yarn

and different collocation between the inner warp and outer warp

thickness

section shape of the same structure being considered especially

a model for predicting the elastic property of 2.5-D woven composites was developed.To verify the elastic model

62 samples of 2.5-D woven composites with 6 various structures were selected and the elastic properties were measured.Experiment results are in good agreement with the outcomes of the model.Further

it is shown that the difference between the inner warp and outer warp can't be ignored in predicting the elastic property of 2.5-D woven composites.
