摘要
以苎麻原麻、纱线、苎麻粗绳、苎麻布为原料,用甲苯-2,4-二异氰酸酯(TDI)进行接枝改性,然后制备出不同苎麻纤维与树脂PE的复合材料。采用扫描电镜(SEM)、电子万能拉伸试验机等分析测试手段对复合材料力学性能和断口进行了测试分析。结果表明:苎麻纤维经过TDI接枝改性后,其复合材料界面性能明显改善。接枝后原麻/PE复合材料复合拉伸性能略有下降,而苎麻绳和苎麻布/PE复合材料拉伸性能明显提高。
The graft copolymerization of TDI onto ramie fibers has been studied using raw ramie, ramie yam, ramie rope and ramie fabric as starting materials, the TDI grafting ramie fiber reinforced PE composite was prepared. The tensile properties and fractography of composites were analyzed by tensile test and SEM. Experimental results show： compare with the un-grafting ramie fiber, the composite interface adhesion are improved after TDI grafting ramie fibers, the tensile properties of TDI grafting raw ramie reinforced PE composite is decreased a little, but the tensile properties of TDI grafting ramie rope and fabric reinforced PE composites are improve obviously.
