先进树脂基复合材料固化过程的铺放缺陷演变规律研究
Evolution of Paving Defects During Curing Process of Advanced Resin Matrix Composites
摘要
Abstract
Taking the paving defects such as fiber wrinkling as the studying targets,the evolution of paving defects of composites during prepreg-autoclave process was studied,and the forming quality and mechanical properties after curing were compared and analyzed.The results showed that using a shorter prepreg during paving and a moderate curing pressure during curing was advantageous to improve the compliance of fibers and the smoothness of specimen,and the paving defects of fiber wrinkling can be effectively reduced.Under the conditions of this experiment,with the composite specimen length of 70mm and the curing pressure of0.4MPa,the improvement effect of fiber wrinkling was relatively remarkable.In addition,the relatively high mechanical properties can be obtained after curing.关键词
