摘　　要：对分别采用聚苯醚(PPO)、聚丙烯酸酯(PAK)改性的环保型酚醛树脂(PF)的热分解过程进行了差热分析,并探讨了玻璃纤维(GF)增强这两种改性PF在300℃/200h热老化过程中的力学性能与电性能的变化情况。结果表明,在300℃老化200h后,PF/PAK/GF的力学性能优于PF/PPO/GF和PF/GF;而PF/PPO/GF的电性能优于PF/PAK/GF和PF/GF。The prolysis processes of phenolic resin （PF） modified by polyphenylene oxide （PPO） and polyacrylate （PAK） are analyzed, and the mechanical properties and electrical properties of these two modified materials reinforced by glass fiber （GF） during heat ageing of 200 hours at 300℃ are discussed. The results show that the mechanical properties of PF/PAK/GF are better than those of PF/PPO/GF and PF/GF and the electronical properties of PF/PPO/GF are the best.
