Although the properties of selvage are identical to those of fabric, the use of selvage is still fairly limited. In the present study, the compressive strength and tensile behavior of engineered cementitious composites (ECCs) reinforced by polyethylene (PE) filament-based selvage short fibers were investigated. Three methods for processing selvages into short fibers were also proposed. Using the three methods, three types of selvage short fibers were fabricated, and a total of four ECCs were then manufactured using the three selvage short fibers along with a normal PE short fiber. Compressive strength and tension tests were performed. The test results showed that while the compressive strength was not significantly affected by the type of selvage short fiber, the tensile strength and tensile strain capacity were found to highly depend on the fiber types. Material sustainability indicators indicated that ECC using selvage short fibers has high sustainability.

PE基布边纤维增强工程水泥复合材料的高延展性和可持续性

尽管布边的特性与织物相同,但布边的使用仍然相当有限。在本研究中,研究了聚乙烯 (PE) 长丝基布边短纤维增强工程水泥复合材料(ECC)的抗压强度和拉伸性能。还提出了三种将布边加工成短纤维的方法。使用这三种方法,制造了三种类型的镶边短纤维,然后使用这三种镶边短纤维和普通的PE短纤维共制造了四种ECC。抗压强度和拉力测试进行了。测试结果表明,虽然抗压强度不受织边短纤维类型的显着影响,但发现拉伸强度和拉伸应变能力高度依赖于纤维类型。材料可持续性指标表明,使用镶边短纤维的ECC具有较高的可持续性。
