利用同轴共纺技术制备PMMA/PA6壳芯结构的复合纳米纤维,在芯层PA6纤维中添加经过表面处理的MWNTs,并且利用热压成型技术将壳层的PMMA部分熔融成为透光复合材料的树脂基体,而PA6纤维成为纤维增强体。由于PA6纤维中MWNTs的存在,PA6纤维的力学性能明显提高,作为透光复合材料的纤维增强体进一步提高了复合材料的拉伸性能,同时基本保持了原有的PMMA/PA6透光复合材料的可见光透过率。
The composite nanofibers with PMMA / PA6 shell-and-core structure were prepared by co-axial spinning technology, the surface-treated MWNTs were added to the core PA6 fiber, and the PMMA of the shell was partially melted into the light-transmitting composite by hot- Resin matrix, while PA6 fiber becomes a fiber reinforcement. Due to the existence of MWNTs in PA6 fiber, the mechanical properties of PA6 fiber are obviously improved. As the fiber reinforced material of the light-transmitting composite material, the tensile property of the composite material is further improved while the original PMMA / PA6 light-transmitting composite material Visible light transmittance.
