Notes:
Short fiber composites based on polypropylene (PP)-polyamide (PA) blends were studied using compatibilizers comprising maleic anhydride modified polypropylene. Results have shown that the structure and morphology developed and the resultant mechanical properties of the blend composites strongly depend on the number of acid functional groups in the compatibilizers. The impact strength and tensile modulus of the PP-PA blend composite more than doubled compared with PA and PP short fiber composites, respectively. Furthermore, analytical methods characterizing nonisothermal crystallization were used to investigate the crystallization of fiber containing blends in constrained matrix nucleation mode. Results have shown that interphase interactions are the dominant ones with respect to morphology development. Synergistic effects were obtained that were due to the effect of fibers.
