在本工作中，研究了制造后从复合材料表面剥离层的去除过程。复合材料样品采用真空辅助工艺 (VAP) 制造。所需的剥离力和断裂能由分析模型证实的剥离测试确定。使用钻孔样品，断裂能与纤维断裂的发生相关。详细研究了剥离角度和剥离层方向的影响。在初步试验中，它们被认为具有重要意义。分析了不同剥离层产品的剥离力。据观察，尖锐的剥离角度和剥离层产品对聚合物基体系统的适应性有利于减少缺陷。 (C) 2015 Elsevier Ltd. 保留所有权利。
In the presented work, the removal process of peel ply from composite surfaces after manufacturing is investigated. Composite specimens are manufactured using the Vacuum Assisted Process (VAP). The required peel force and fracture energy are determined by a peel test corroborated by an analytical model. The fracture energy is correlated to the occurrence of fiber breakouts using drilled samples. The influence of the peel angle and the peel ply orientation are investigated in detail. In preliminary trials they were identified to be of main importance. The peel force of different peel ply products is analyzed. It is observed that a sharp peeling angle and an adaption of the peel ply product to the polymer matrix system are beneficial in reducing defects. (C) 2015 Elsevier Ltd. All rights reserved.
