通过模压工艺制备了苎麻纤维织物增强酚醛树脂基复合材料层合板,研究了模压层合板在不同湿热环境下的水吸收与扩散及力学性能.研究表明:在20℃,40℃和60℃三种温度下,相对湿度的上升使层合板瞬时吸湿速率增大很明显,而在50％相对湿度下,温度对层合板的饱和吸水率的影响不大.当吸湿份数在0.5以下时,层合板在50％的相对湿度和20℃,40℃和60℃三种温度下,水扩散系数分别为2.16 x 10-6 cm2/s,2.94×10-6cm2/s和6.61×10-6 cm2/s.层合板的力学性能随吸水率的增加而下降.通过扫描电子显微镜(SEM)观察,层合板力学性能下降的主要原因是水分破坏了纤维和树脂的界面,同时进入纤维的空隙中,影响了复合材料中的应力传递,使复合材料力学性能下降.
