Performance Characterization of Modified Ultra-high Molecular Weight Polyethylene Fibers for Aerobics Equipment
In order to further optimize the comprehensive performance of sports equipment such as aerobics,this article uses aminopropyltriethoxysilane as a modifier to prepare ultra-high relative molecular weight polyethylene fibers for aerobics equipment,and its properties are tested and characterized.The results show that compared to unmodified ultra-high molecular weight polyethylene fibers,ultra-high molecular weight polyethylene fibers modified with aminopropyltriethoxysilane have higher melting peak temperatures,lower DSC and XRD crystallinity,lower fracture strength,elastic modulus,and elongation at break,while interface shear strength is relatively higher;UHMWPE fibers modified with aminopropyl triethoxysilane have good thermal stability and wear resistance;as the creep temperature increasing,the improvement effect of aminopropyltriethoxysilane modification on the creep resistance of UHMWPE fibers become increasingly prominent.
