    摘要:

    以纤维皱曲此类典型铺放缺陷为研究对象,研究了预浸料-热压罐工艺过程中复合材料铺放缺陷的演变规律,并对其固化后成形质量及力学性能进行对比分析。研究表明:较短预浸料铺贴及适中的固化压力,有利于提高固化过程中纤维顺应性及试件平整性,可有效弱化纤维皱曲此类铺放缺陷;本实验条件下,70 mm复合材料试片在0.4 MPa固化压力下对铺放缺陷的改善效果相对最显著,固化后试片可获得相对较高的力学性能。

    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 of 0.4MPa, the improvement effect of fiber wrinkling was relatively remarkable. In addition, the relatively high mechanical properties can be obtained after curing.
