摘要: 为了提高玻纤增强聚丙烯(PP)的界面粘结,分别用B301或硅烷偶联剂对玻纤表面进行了处理,用过氧化物和顺丁烯二酸酐对PP进行了改性。经处理和改性后,PP/GF复合材料的弯曲强度有明显提高,对玻纤增强聚丙烯的界面结构也作了探讨。Abstract: n order to improve the interface bonding of glass fiber reinforced polypropylene, glass fiber was treated with B301 or silane coupling agents and PP was modified with a peroxide and maleic anhydride. The bending strength of the composite is increased obvi
