采用热塑性聚芳醚酮(PAEK)与环氧树脂制得预聚体,并用预聚体改性酚醛树脂,起到增韧作用。通过红外光谱、综合热分析和力学性能测试对复合材料进行性能表征。研究结果表明,材料的韧性和热性能对PAEK的含量有一定的依赖性。红外光谱分析表明,PAEK固化过程中没有参与反应;热分析表明,改性的酚醛树脂复合材料的耐热性良好,最高热分解温度为525℃。
The use of thermoplastic poly (aryl ether ketone) (PAEK) prepolymer with epoxy resin, and modified phenolic resin with a prepolymer, play a role in toughening. The properties of the composites were characterized by infrared spectroscopy, comprehensive thermal analysis and mechanical properties testing. The results show that the toughness and thermal properties of the material have a certain dependence on the PAEK content. Infrared spectrum analysis showed that PAEK did not participate in the reaction during the curing process. Thermal analysis showed that the modified phenolic resin composites had good heat resistance and the highest pyrolysis temperature was 525 ℃.
