研究了超高相对分子质量聚乙烯(UHMWPE)对碳酸钙/高密度聚乙烯(HDPE)复合材料韧性的影响。采用双螺杆挤出-模压成型工艺制备了碳酸钙含量为0~40%、超高相对分子质量聚乙烯含量为0~50%的二元和三元高密度聚乙烯基复合材料。拉伸和冲击试验表明，随着碳酸钙含量的增加，复合材料的拉伸模数增加，但拉伸强度、断裂应变和抗冲击性能降低。UHMWPE的加入有助于在不降低弹性模量和强度的前提下，适度提高复合材料的断裂应变和抗冲击性能。增韧程度随UHMWPE含量的增加而增加，但随填料体积分数的增加而降低。©2000 John Wiley&Sons，Inc.《应用波利姆科学》75：1503-1513,2000
A study of the influence of employing ultrahigh molecular weight polyethylene (UHMWPE) on the toughness of CaCO3/high-density polyethylene (HDPE) composites was carried out. Binary and ternary HDPE-based composites with calcium carbonate in the range of 0–40% and UHMWPE in the range of 0–50% were produced by twin-screw extrusion followed by compression molding. From tensile and impact tests, it was found that increasing calcium carbonate content increased tensile modulus, but decreased tensile strength, strain at break, and impact resistance. The addition of UHMWPE helped to increase the strain at break and impact resistance of composites moderately without decreasing modulus or strength. The degree of toughening was found to increase with increasing UHMWPE content, but to decrease as the filler volume fraction was increased. © 2000 John Wiley & Sons, Inc.
