| 摘 要： | 为改善炭纤维网胎的针刺性能,采用二甲基硅油、咪唑啉、水溶性二甲基硅油等表面剂处理炭纤维网胎,按照相同针刺工艺制备试验件.扫描电镜结果表明,二甲基硅油处理后网胎纤维相互粘连,水溶性二甲基硅油处理后的网胎呈疏松状态,纤维表面光滑.3种表面剂处理的针刺试样Z向剥离强度,咪唑林达到0.144 MPa,其余两种达到0.128 MPa.相对于咪唑啉和二甲基硅油,水溶性二甲基硅油可与水以任意比例互溶,且成本低,为理想的炭纤维网胎表面处理剂.

| Abstract: | To improve needling property of the carbon fiber felt,dimethyl siloxane,imidazole and water-soluble dimethyl siloxane were used as the surface modification agent of fiber felt.Then the samples were prepared by using the same needling process.The SEM shows that the felt fibers are conglutinated each other after treated with dimethyl siloxane,but the felt fibers after treated with the water-soluble dimethyl siloxane are loose and their surface is smooth.Among three kinds of samples,the peel strength of the sa... |
