Fatigue behaviors of glass fiber-reinforced Nylon 6 were studied based on dynamic viscoelastic measurements during the fatigue process. The fatigue strength of glass fiber reinforced Nylon 6 was greatly improved by strengthening the interfacial adhesion between glass fiber and matrix polymers. The heat generation rate under cyclic fatigue for Nylon 6 reinforced with surface-unmodified short glass fiber was always larger than that reinforced with surface-modified short glass fiber because of the large net imposed strain amplitude to the matrix polymers. This might be attributed to the interfacial debonding under cyclic fatigue. A fatigue fracture criterion based on the magnitude of hysteresis energy loss being consumed for a structural change was established for the (Nylon 6/short glass fiber) composites in consideration of glass fiber-matrix polymer interfacial interaction.
