摘要
研究了用稀土元素 (RE)处理玻璃纤维表面的最佳用量及其对玻璃纤维增强聚四氟乙烯 (GF/PTFE)复合材料拉伸性能的影响。测试了不同表面处理条件下GF/PTFE复合材料的拉伸性能 ,并对断口形貌进行了SEM分析。结果表明 ,由于RE对亲和性的作用 ,RE能够有效地提高玻璃纤维与PTFE之间的界面结合力。当稀土元素在表面改性剂中的含量为 0 2 %～ 0 4%时 ,GF/PTFE复合材料的拉伸性能得到明显提高 ,并且在RE含量为 0
The optimum amount of rare earth elements (RE) for treating glass fiber surface and its effect on the tensile properties of glass fiber reinforced polytetrafluoroethylene (GF/PTFE) composites were investigated. The tensile properties of GF/PTFE composites with different surface treatment conditions were measured. The fracture surface morphologies were observed and analyzed by SEM. The results indicate that rare earth elements can effectively promote the interfacial adhesion between the glass fiber and PTFE, owing to the effects of rare earth elements on the compatibility. The tensile properties of the GF/PTFE composites can be improved considerably when the content of RE in surface modifier is 0 2%～0 4%, and the optimum performance of the GF/PTFE composites is obtained at 0 3% RE content.
