【摘要】 本文研究了以冷等离子体处理及未经处理的两种芳纶纤维增强环氧树脂复合材料的吸湿行为。结果表明，扩散系数随环境湿度增大而增大。此外，还研究了扩散系数对芳纶纤维复合材料的层间剪切强度的影响。更多还原

【Abstract】 This paper studies moisture properties of two kinds of epoxy resins composite materials of Kevlar fiber which is untreated and treated by means of cold plasma. The result shows that the diffusion increases with the increase of relative humidity. Besides,the effect of diffusion coefficient on interlaminer shear stength of composites is investigated.更多还原
