摘要
以长玻璃纤维(GF)和聚醚醚酮(PEEK)为原料,采用挤出造粒的方法制备了高性能PEEK/长GF复合材料,并对其微观形貌、热性能及力学性能进行了研究。结果表明,长GF与PEEK结合紧密,当长GF质量分数为15%时,PEEK/长GF复合材料的热分解温度比纯PEEK提高了55℃,拉伸强度、剪切强度及弯曲强度分别提高了70%、46%和68%。
The high performance PEEK/long glass fiber（GF） composite was prepared by means of extrusion pelletization with the raw material of long Glass Fiber and pure PEEK, and the micro-morphology, thermal performance and mechanics property of the composite were studied. The results indicated that the combination of long GF and PEEK was tight, the thermal decomposition temperature of PEEK/long GF composite had a increase of 55℃ compared with that of pure PEEK when the mass fraction of long GF was 15%, and the tensile strength, shear strength and flexural strength of the composite were increased by70%, 46% and 68% respectively.
