摘　　要：采用硅烷偶联剂(KH550)对玻璃纤维进行表面处理,并对改性玻纤进行红外分析,结果证明硅烷偶联剂使玻璃纤维表面基团增加。用改性玻纤制备改性玻纤/聚氨酯复合材料,与原玻纤增强聚氨酯材料的力学性能及泡孔结构进行对比。结果表明:硅烷偶联剂处理能够提高玻璃纤维与聚氨酯基体的界面强度,改善玻璃纤维在聚氨酯基体中的分散情况,使玻璃纤维/聚氨酯复合材料的力学性能提高,同时改善复合材料的泡孔结构。The surface of glass fiber was treated by the silane coupling agent（silane coupler KH-550）,Infrared analysis of glass fibers were conducted and confirmed the surface-modified glass fibers had remarkably more lipophilic group on the surface.The glass fiber/polyurethane foam was prepared,and the mechanical property of modified glass fiber/Polyurethane foam was compared to that of raw glass fiber/polyurethane foam.The resulted showed that the treatment of silane coupling agent can improve the dispersion of glass fiber in polyurethane matrix,increased the interfacial strength between glass fibers and matrix.Thus,the mechanical property and foam structure of glass fiber/polyurethane was improved.
