缝合碳纤维缎纹织物复合材料研究

Study on Stitched Carbon Fabric Satin Weave Composites

使用高强度玻璃纤维缝合G803-T300-40B五枚缎纹碳纤维织物预制体,并用树脂膜熔融渗透(RFI)工艺成型复合材料。测试了改性环氧树脂胶膜熔体粘度对固化温度和时间的依赖性,将缝合与未缝合复合材料层合板试样的基本力学性能进行了试验对比。

Layers of dry carbon fabric satin weave G803-T300-40B were stacked and stitched through the thickness with high strength glass threads.RFI of perform with modified epoxy resin followed by autoclave curing process.Viscosity of the RFI resin film as a function of curing temperature and time were tested respectively.The mechanical properties of stitched and unstitched composite laminates were evaluated.
