聚丙烯工程纤维物理力学性能探讨

为探讨聚丙烯纤维的物理力学性能,对实验室2005～2008年四年时间内检测的近200个聚丙烯纤维样品物理指标进行分析,并与国家标准GB/T21120—2007《水泥混凝土和砂浆用合成纤维》和行业标准JT/T525—2004《公路水泥混凝土纤维材料聚丙烯纤维和聚丙烯氰纤维》比较,发现我国聚丙烯工程纤维的物理力学性能基本满足各自企业标准要求,达到甚至超过国家标准和行业标准的规定。

Discussion about Physical and Mechanical Properties of Polypropylene Fiber

To explore the physical and mechanical properties of polypropylene fiber, our laboratory analysis physical indicators about nearly 200 test samples of polypropylene fiber in four-year period from 2005 to 2008, and compared with the national standard GB/T 21120--2007 ＂ Synthetic fibres for cement cement mortar and concrete＂ and industry standard JT/T 525--2004 ＂Fiber for cement concrete in highway polypropylene fiber and acrylic fiber＂ . The results showed that physical and mechanical properties of our country polypropylene fiber can basically meet the standard needs; the properties can meet or exceed the national standards and industry standards too.
