摘要
在经过偶联剂改性的玻璃纤维(GF)基础上,进一步采用真空等离子体表面处理进行改性,研究了在表面引入活性基团的同时,等离子体处理时间对表面产生的刻蚀缺陷程度及其对环氧树脂(EP)的增强增韧效果的影响。结果表明:通过适当的等离子体处理,可以在经过偶联剂处理的GF表面引入额外的活性基团,这种处理有助于提高玻璃纤维的表面活性,改善其浸润性,从而增强玻璃纤维与EP之间的相容性和界面黏结力。最终,这种改进能够显著提高材料的机械性能。但是,过长的等离子体处理时间将导致玻璃纤维表面产生过多的刻蚀缺陷,反而降低了复合材料的力学性能。当真空等离子体处理时间为1.0 h时,效果较佳。
Based on the glass fiber(GF)modified by coupling agent,the vacuum plasma surface treatment process was further used to modify it.The effect of plasma treatment time on the degree of etching defects produced on the surface and its strengthening and toughening effect on epoxy resin(EP)while introducing active groups on the surface were studied.The results showed that through appropriate plasma treatment,additional active groups were introduced on the surface of GF treated with coupling agent.This treatment could improve the surface activity of glass fiber and improve its wettability,thereby enhancing the compatibility and interfacial adhesion between glass fiber and EP.Ultimately,this improvement could significantly improve the mechanical properties of the material.However,too long plasma treatment time could cause many etching defects on the surface of glass fiber,which reduced the mechanical properties of the composite material.The effect was better when the vacuum plasma treatment time was 1.0 h.
