摘　　要：分别对短切剑麻纤维 (SF)和聚丙烯 (PP)进行接枝丙烯酸 (AA)预处理后 ,采用片状层压工艺制备了SF/PP、SF/PP- g- AA、SF- g -AA/PP复合材料 ;测试了复合材料的力学性能 ,并观察了复合材料的断面形态。结果表明 :SF/PP- g -AA复合材料的综合力学性能比SF/PP复合材料有明显提高 ,而SF -g -AA/PP复合材料的综合力学性能反而比SF/PP复合材料差。Acrylic acid was grafted onto PP and sisal fiber (SF), and SF/PP, SF/PP-g-AA and SF-g-AA/PP composites were prepared by means of sheet laminated moulding, the mechanical properties of the composites were measured and the morphology of the fractured section of the composite was studied The results showed that the comprehensive mechanical properties of SF/PP-g-AA were much better than those of SF/PP composite, while the comprehensive mechanical properties of SF-g-AA/PP were worse than those of SF/PP composite
