Abstract: 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.

Key words: carbon/glass fiber reinforced plastic, compression springs, static stiffness, maximum working load
