	汽车座椅及内饰产品中一些零件常用到PA复合材料，其干态与湿态条件下的韧性差异很大。本文研究了PA6-GF15样条的含水率受环境温湿度的变化规律及对缺口冲击强度的影响，结果表明随时间的变化，在干燥的环境中含水率逐渐降低，在湿润的环境中含水率会缓慢上升；样条含水率发生变化后，低温缺口冲击强度变化不大，室温下的缺口冲击强度会随含水率的变化而发生显著变化。<br />
PA composite always used by seats and interior parts, in which toughness property is a significant difference between the condition of dry and humid. In this paper, we studied the environmental temperature and humidity changes effect to PA6-GF15 samples performance such as water absorption and notched impact. The results show that water content of PA6-GF15 samples gradually reduced in the dry environment and increased in humid environment; at low temperature, notch impact strength was not obviously affected by water absorption but obviously at room temperature.
