依据自动铺带头的结构从离型纸与预浸带的作用、预浸带间的粘附性、预浸带对模具的粘附性这3个影响自动铺放成功的方面简介了预浸带的自动铺放适宜性的评价方法。首先,通过离型纸剥离力的测量和比较可以选择出适合自动铺放的离型纸。其次,通过楔子剥离测试预浸带间的平均剥离力,为选择出一定温度下适宜自动铺放的预浸带提供了参考。最后,通过预浸带与垂直金属板间的粘性测量,为选择适宜在金属模具表面自动铺放的预浸料提供指导。
According to the structure of automatic paving head from the role of release paper and prepreg tape, prepreg tape adhesion, prepreg tape adhesion to the mold of these three effects of automated placement success Introduction prepreg tape The evaluation method of automatic placement suitability. First, the release paper suitable for automatic placement can be selected by measuring and comparing the release force of the release paper. Secondly, the average peel force between prepreg strips was tested by wedge peel test, which provided a reference for prepreg strip which was suitable for automatic placement at a certain temperature. Finally, the viscosity measurement between the prepreg tape and the vertical metal plate provides guidance for selecting the prepreg suitable for automatic placement on the surface of the metal mold.
