摘　　要：碳/玻璃纤维混编复合材料(C/GFRP)压簧相比碳纤维复合材料(CFRP)压簧具有纤维材料利用率高、成本低的特点。针对拥有PU内芯的C/GFRP压簧,根据其静刚度与最大工作载荷的理论分析,计算给定静刚度与最大工作载荷下的压簧结构参数;提出一种C/GFRP压簧的制作方法,制作压簧试件;对试件进行准静态力学性能实验,得出试件的静刚度与最大工作载荷。实验表明,试件静刚度、最大工作载荷与理论值结果误差分别为6.92%、4.43%,验证此种制作方法可以应用于工程实际C/GFRP压簧的定制化生产,C/GFRP压簧可以成为CFRP压簧的低成本替代品。Carbon/glass fiber reinforced plastic(C/GFRP)compression springs have the advantages of high mechanical property efficiency and low cost,compared with carbon fiber reinforced plastic(CFRP)compression springs that are mainly used in vehicle suspension system.Based on the mechanics of composite laminate theory,the calculation method of static stiffness and maximum working load of C/GFRP springs with PU inner core has been put forward,and the structural parameters are calculated.A new method of manufacturing process of C/GFRP compression springs is presented and specimens are made.By testing the quasi-static mechanical properties of specimens,the static stiffness and maximum working load are obtained,the error of them are 6.92%and 4.43%,respectively,which verifies that this manufacturing method can be applied to the customized production of C/GFRP compression springs,and C/GFRP springs can be a low-cost substitute for CFRP springs.
