摘　　要：在考察并优化不同基体树脂配方情况下,采用熔融混合的方式制备了不同含量的短切玻璃纤维增强二氮杂萘联苯聚芳醚砜(PPBES)/聚醚醚酮(PEEK)复合材料。并对复合材料不同温度下的力学性能进行了研究。玻璃纤维增强后,体系的拉伸强度大幅提高,其中30%玻璃纤维增强复合材料在150℃的拉伸强度稳定在91 MPa,具有优异的高温力学性能。扫描电子显微镜(SEM)照片表明复合材料中玻璃纤维和基体有较强的相互作用。After determining the blend matrix composition, the copoly （ether sulfone） containing phthalazinone and biphenyl moiety （PPBES） and poly（ether ether ketone） （PEEK） blend reinforced by different composition short glass fiber were prepared via melt mixing. The effect of glass fiber content in composite on mechanical properties of the composite was observed at room temperature and 150 ℃, respectively. Adding short glass fiber results in the increase of tensile strength and flexural strength of the composites and excellent tensile strength at elevated temperatures. The composite with 30% glass fiber has the tensile strength at 91 MPa. Scanning electron microscopy （SEM） results indicate that there exist a strong interaction between glass fiber and the polymer blend matrix.
