摘要
论述和分析木质剩余物复合材料老化的原因,主要有木质剩余物的老化、胶粘剂的老化、木质剩余物的回弹和膨胀—收缩应力。综合论述木质剩余物复合材料加速老化试验方法,指出木质剩余物复合材料在加速老化试验方面的研究,适宜采用ASTM D1037六循环加速老化法和老化仪检侧法。分析木质剩余物复合材料老化的影响因素,如温度、湿度、试件尺寸等。
Reasons for the aging of wood residues composite were discussed and analyzed, which were the aging of wood residues, the aging of adhesive, and the rebounding and expansion contraction stress. And then, testing measures of the accelerated aging of wood residues composite was introduced pointing out that ASTM D1037 6 - cycle accelerated aging method and aging instrument detection method would be used. Influencing factors of aging of wood residues composite were temperature, humidity, sample size, etc.
