Influences of recycling process on the fatigue crack growth property of PA・MXD6 were examined. The main results obtained were as follows : (1) The FCP property of recycled PA・MXD6 became worse than that of the virgin material. In particular, the decline of the fatigue property was fastest in the first recycling process. (2) From the fractography using SEM, it was understood that the detrimental effect of the recycling process on the fatigue property was caused by the breakdown of the glass fibers during the recycling process. (3) The crack tip heating in the recycled material was increased more remarkably than in the virgin marerial. This is because the crack tip opening displacement was increased more markedly than in the virgin material. Therefore, it could be interpreted that the influence of the recycling process on the FCP property was caused by enlarging the crack tip opening.
