Bulk Crystallization of Polymers in Contact with a Foreign Surface

4 BULK CRYSTALLIZATION OF POLYMERS IN CONTACT WITH A FOREIGN SURFACE 

Moreover, if the fiber is in the crystalline state, as in the case of surface-induced polymer epitaxy, lattice matching between the polymer and fiber crystals provides another favorable situation for transcrystallization. For example, the existence of excellent matching of nylons and iPP with high-modulus graphitic carbon fibers has led to the transcrystallization of nylons and iPP around the carbon fibers [135]. Taking this into account, the case in which both fiber and matrix are of 

This is reasonable, because the iPP fibers can exist only in the a-form due to the / a transition on stretching. 

The crystallization rate of the / -iPP plays a very important role. When the iPP fiber melts at temperatures slightly over 

The nucleation of -iPP crystals can be controlled by adjusting the fiber introduction temperature. For this purpose, the crystallization temperatures in all experiments were set
