中文摘要：
采用密炼方式分别制备碳纤维（CF）、玻璃纤维（GF）、芳纶纤维（AF）增强聚丙烯（PP）母粒,通过注塑成型制备相应的聚丙烯/纤维复合发泡材料,研究了3种纤维对微发泡聚丙烯/纤维复合发泡材料力学性能的影响。结果表明,PP/CF复合发泡材料的综合性能提高的幅度最大,其中拉伸、压缩、弯曲强度分别提高了100.9%,80.4%,126.5%;PP/AF复合发泡材料的韧性最好,相对于纯PP提高了151.2%;并且,PP/CF复合发泡材料的泡孔参数最好,泡孔尺寸为28.97μm,泡孔密度为8.58×106cm^-3,泡孔尺寸分布达到9.22μm。
英文摘要：
Polypropylene（ PP） reinforced composites with three different fibers,such as carbon fiber（ CF）,glass fiber（ GF）,aramid fibers（ AF）,were prepared by banburying and then foamed by injection molding method. The effects of different fibers on mechanical properties of microcellular foams were investigated. The results indicate that PP / CF shows the best comprehensive mechanical properties among three fiber reinforced foams,whereas PP / AF exhibits the best toughness. Compared with PP microcellular foams,the tensile,compressive,and flexural strength of the PP / CF increase by 100. 9%,80. 4%,and 126. 5%,respectively while the toughness of PP / AF increases by 151. 2%. In addition,the cell diameter,cell density,and cell size distribution of PP / CF composite are 28. 97 μm,8. 58 × 106cm- 3,and 9. 22 μm,respectively,which exhibit the best cell structure parameter among fiber reinforced foams.
