摘要
选择高韧性环氧树脂作为碳纤维表面涂层处理剂,研究了碳纤维表面聚合物涂层韧化处理对其复合材料性能的影响,探讨了界面韧化的作用机理。结果表明:高韧性环氧涂层能提高单向复合材料的层剪、拉伸及冲击等性能,且处理工艺简单;涂层处理后Φ150mm复合材料压力容器强度转化率由81%提高到86.4%。
Epoxy resin with high toughness is chosen as a coating agent for carbon fiber. The effects of coating on composite properties and the mechanism of interface toughness are investigated. The results show that the epoxy coating with high toughness can improve the interlaminate shear, tensile and impact properties of composites. The translation rate of fiber strength of Φ150 mm pressure vessel by coating treatment can be improved by 81% to 86.4%.
