Crystallization behavior and effect of thermal treatment on fracture performance of glass flake reinforced polypropylene

摘要: In this work, the role of interface and matrix morphology in determining fracture behavior glass flake reinforced polypropylene is investigated. Differential scanning calorimetric analysis shows that silane coupling agent modifies crystallization matrix. Silane treated flakes prepared by dry blending are found to induce nucleation decrease rate development crystalline entities during process. This effect attributed physisorbed layer on flakes. The performance analyzed mechanics. An increase crystallinity pure flake/polypropylene composites leads a reduction maximum crack growth resistance. lower ductility more results energy dissipated stretching and, therefore, concomitant energy. Although seemed be important case untreated composites, negligible for composites. Nevertheless, microscopic observation surfaces also revealed highly samples. improvement matrix-filler seems inhibit
