聚氨酯上浆剂处理对芳纶纤维表面及界面性能的影响
Effects of the polyurethane sizing agent on surface and its interfacial properties for the aramid fiber
摘要
Abstract
Waterborne polyurethane(WPU)sizing agent was used to modify aramid fiber(AF)and improve the interfacial bonding properties for AF and thermoplastic polyurethane(TPU)resin.The structure,surface ele-ment composition and morphology of AF were characterized by Fourier transform infrared spectroscopy,X-ray pho-toelectron spectroscopy and scanning electron microscopy.The results showed that WPU sizing agent was successfully coated on the AF surface.The effects of WPU content on the surface energy,interlaminar shear strength of aramid fibers and TPU were studied.It is found can improve the surface roughness and surface energy of fiber sur-face with various WPU content.When the content of WPU sizing agent is 0.8wt%,the surface energy of WPU-AF is increased by 28.91%,while the interlaminar shear strength is 32.7 MPa,increased by 37.9%.关键词
