The creep properties, that is, the velocity constant, activation energy, stress index, and time index, of a test piece (TP) cut from a glass-fiber-reinforced nylon 6 product were successfully determined by a compression creep test. In the determination of the creep properties, the experimental creep curves for the TP were fitted by finite element analysis (FEA). Fiber-reinforced nylon 6 beams with different fiber orientations were also prepared, and their creep properties were successfully determined by a combination of the bending creep test and the corresponding analysis. The creep behavior of the press-fit component composed of a metal collar and a fiber-reinforced nylon 6 product was predicted by FEA with the determined creep properties of the TP. The predicted retention forces were in good agreement with the experimental ones. The effects of the fiber orientation on the long-term reliability of the press-fit component are also discussed.
