Crystallization Behavior and Properties of Glass Fiber Reinforced Polypropylene Composites

Glass fiber with different content and different kinds of compatibilizers were used to prepare glass fiber-reinforced polypropylene (GFRP) composites. β-nucleating agent with different content was used to prepare β-polypropylene (PP), after which the toughness, crystallization abil...
