| 摘 要： | 在准静态单向压缩条件下,测试和分析了聚丙烯(PP)/乙烯-1-辛烯共聚物(POE)/短玻璃纤维(SGF)三元泡沫复合材料的压缩性能,考察了SGF的质量分数对压缩弹性模量、屈服强度和能量吸收特性的影响.结果表明:PP/POE/SGF泡沫复合材料的压缩应力-应变曲线具有典型的弹性变形、屈服平台和致密化三个阶段;适量SGF的引入提高了压缩弹性模量、屈服强度和吸能能力,而在研究的范围内,较高含量(20%以上)的SGF才能提高泡沫复合材料的吸能效率,其增强效果不如吸能能力明显.

| Abstract: | The compressive properties of polypropylene(PP)/ethylene-1-octene copolymer(POE)/ short glass fiber(SGF) ternary foamed composites were tested and analyzed under the quasi-static and uniaxial compressive loading condition.The effects of mass fraction of SGF on the modulus,yield strength and energy absorption behavior were discussed.The results show that the compressive stress-strain curves of PP/POE/SGF foamed composites are consisted of three typical stages: elastic behavior,plastic plateau and densificati... |
