英文摘要: Abstract(#br)Glass fiber (GF)-reinforced polypropylene composites show high flammability due to wicking actions, which results in accelerated flow of the polymer melt along the GF surface to the flame zone. The conventional bulk charring mode, in which high loading of flame retardants are evenly distributed in the bulk matrix to catalyze the resin into an integrate char-barrier so that the entire composite surface could be covered, is quite inefficient and uneconomic. In this research, an interfacial charring mode differing from the bulk one has been proposed to solve the challenge. The acid-source flame retardants grafted on the GF surface can rapidly carbonize the interfacial resin to form a char layer, which can locally encapsulate the GF during combustion, thus converting the original...
