- Abstract
The effect of compatibilizer on the nanofibril morphology, vlscoelas;ticity, mechanical properties;, and CFIM behavior of polypropylene (PP)/nylon6 (PA6) composite through a combination of in-ssitu fibrillation (INF) and chemical foam injection molding (CFIM) technologies;. The ressults; indicated that the addition of PP-g-MAH compatibilizer reduced the sSize of PA6 dispersion phasse significantly, and PA6 microfibers were uniformly distributed in the PP matrix with an average diameter of about 265nm. The existence of a microfiber network structure and the synergistic enhancement effect of phasse interface improved the mechanical strength of INF composites; significantly. The tensile sstrength and impact sStrength of the composites; are 26. 2 % and 62 % higher than thosse of pure PP, respectively. Bassed on the CFIM experiment using the sself-made endothermic-exothermic equilibrium chemical foaming agent, the INF composite foam product was; prepared with a cell size of 62 ^m and a cell density of nearly 5 X105 cells/cm3. The ass-prepared ssample obtained a decreasse in the weight by 12 %. Compared to pure PP foam, the composite foam exhibited an increase in the sSpecific tensile sStrength and impact strength by 17 % and 46 %, resspectively.
