摘要/Abstract

摘要： 为研究不同装配工艺参数对碳纤维增强树脂基复合材料(CFRP)构件弯曲性能的影响规律,以碳纤维增强树脂基复合材料为实验对象,以DNS100电子万能试验机为实验平台,通过对比不同装配工艺参数对复合材料构件的极限承载性能、刚度、损伤发生时刻的影响,分析了装配钉距、间隙尺寸和间隙补偿材料等装配工艺参数改变对复合材料构件弯曲性能的影响规律。结果表明:在一定范围内,通过增大装配钉距可以有效提高构件的刚度;装配间隙对复合材料构件弯曲性能的影响与构件厚度密切相关;实验条件下液体垫片在提高构件刚度方面的效果强于玻璃纤维垫片。

Abstract: In order to study the influence of different assembly process on bending performance of carbon fiber reinforced resin plastics (CFRP), experimental studies were carried out on the DNS100 electronic universal testing machine. By comparing the ultimate load, assembly stiffness and failure time, the influence of assembly process such as pitch of holes, gap size and shimming material on the bending performance of composite assemblies is analyzed. The results show that, within a certain range, increasing pitch of holes can effectively improve the stiffness of the assembly. The effect of assembly gap on the bending performance is closely related to the thickness of the assembly. In some cases the liquid shim is better than the glass fiber.

Key words: CFRP, gap, shimming material, bending performance
