摘要
将碳纳米管(CNTs)和硅烷偶联剂(AMEO)分散至纤维表面,制备聚芳硫醚(PAS)/玻璃纤维布/CNTs/AMEO复合材料,并探究复合材料的表面形貌和力学性能。结果表明:未经偶联剂处理的体系中,CNTs与纤维的结合性较弱。将CNTs进行羧化和偶联剂处理,能够提高CNTs和纤维之间的结合强度,提升纤维与PAS之间的应力传递,进一步提高复合材料的力学性能。当AMEO加入量为400、800、1 200、1 600μL/gCNTs,复合材料的拉伸强度分别为352、381、403、390 MPa,弯曲强度分别为380、414、443、478 MPa。由此得出,CNTs和AMEO协同作用明显提高复合材料的力学性能。
Carbon nanotubes(CNTs) and silane coupling agent(AMEO) were dispersed on the fiber surface to prepare PAS/glass fiber cloth/CNTs/AMEO composites, and the surface morphology and mechanical properties of the composites were investigated. The results show that the binding between CNTs and fibers is weak in the system without coupling agent treatment. Carboxylation and coupling agent treatment of CNTs can improve the bonding strength between CNTs and fibers, enhance the stress transfer between fibers and PAS, and further improve the mechanical properties of composites. When the AMEO content is 400, 800, 1 200 and 1 600 μL/gCNTs, the tensile strength of the composite is 352,381, 403 and 390 MPa, and the flexural strength is 380, 414, 443 and 478 MPa, respectively. Therefore, the synergistic effect of CNTs and AMEO can improve the mechanical properties of the composites significantly.
