针对铁基非晶条带玻璃纤维混杂增强树脂基复合材料,研究了表面处理、热处理对非晶条带力学性能的影响,在此基础上选取了适宜的树脂基体,制备了混杂复合材料,测试了基本力学性能并分析了破坏模式。结果表明:酸蚀表面处理对条带的拉伸性能影响很小,但改变了条带的表面形貌和表面能,从而提高了条带与树脂的粘结性能;混杂复合材料纵向拉伸弹性模量符合混合定律,横向拉伸弹性模量主要由非晶条带贡献,并且非晶条带的承载对混杂复合材料的横向拉伸强度起到了一定的作用;弯曲破坏和剪切破坏均产生受压侧纤维层与非晶条带的分层以及纤维断裂。
Aiming at the influence of the surface treatment and the heat treatment on the mechanical properties of the amorphous ribbons for the iron-based amorphous ribbon glass fiber reinforced hybrid composites, a suitable resin matrix was prepared and the hybrid composites were tested. The basic mechanical properties and analysis of the destruction mode. The results show that the acid etching surface treatment has little effect on the tensile properties of the tapes, but changes the surface morphology and surface energy of the tapes to improve the bonding properties between the tapes and the resin. The longitudinal tensile elasticity Modulus accords with the law of mixing. The transverse tensile modulus of elasticity mainly contributes to the amorphous ribbon, and the bearing of the amorphous ribbon plays a certain role in the transverse tensile strength of the hybrid composite. Both bending failure and shear failure Delamination of the pressure-side fibrous layer from the amorphous ribbon, and fiber breakage.
