Abstract

The fatigue reliability of recycled advanced fiber-reinforced thermoplastic resin (FRTP) was examined. In particular the effects of mesoscopic factor on the fatigue crack propagation in PA·46 were considered. Main results obtained as follows: (1) The FCP property of recycled PA·46 was inferior to that of the virgin material. It appears that the detrimental effect of recycling on fatigue property was caused by break-up of the glass fibers during the recycling process. (2) By the thermal method using infrared thermography, it was found that the FCP property of each specimen was related to the crack tip opening displacement. (3) It was found that FCP property in the higher FCP rate range was related to the bridging effect. This was because the FCP property of CF material is superior to that of GF material.
