摘　　要：利用熔融拉挤浸渍工艺制备了长玻纤增强尼龙6复合材料。采用油老化加速试验,获得较高温度条件下,长玻纤增强尼龙6复合材料拉伸强度和弯曲模量随时间的变化关系曲线。通过Arrhenius经验公式,对材料的老化机理和老化寿命进行了推算和分析。结果表明,在50℃和80℃,油浸泡条件下,得到材料使用寿命的安全值分别为3.85 a和1.1 a。The long glass fiber reinforced nylon 6 composites（ LFT-PA6） were prepared by melt pultrusion impregnation process.The aging property of LFT-PA6 was obtained through using accelerated aging test in oil.The tensile strength and flexural modulus of LFT-PA6 composites material were linear declined with the time increasing.The aging mechanism and life of the material were calculated and analyzed by Arrhenius empirical formula.The results showed that the service life of LFT-PA6 composites was 3.85 a and1.1 a under the condition of 50 ℃ and 80 ℃ in oil.
