Composite material laminated plate tensile sample considering aging effect and preparation method of composite material laminated plate tensile sample

The preparation method comprises the following steps: in a composite material laying process, embedding multiple layers of metal plates at two ends, laying composite material layers on the bottommost layer and the uppermost layer of the laminated plate, alternately laying the composite material and the metal plates in the middle, cutting the composite material into a dumbbell test piece, and carrying out aging treatment on the dumbbell test piece to obtain the composite material laminated plate tensile test piece. A plurality of dumbbell test pieces are processed at a time, and the two ends are sealed during damp-heat aging, so that aging of the two ends is avoided, clamping parts at the two ends are prevented from falling off in the tensile test process, and the sample piece processing efficiency is also improved. 本发明公开了考虑老化效应的复合材料层合板拉伸试样及其制备方法，包括：在复合材料铺层过程中，在两端嵌入多层金属板，层合板的最底层和最上层是复合材料铺层，中间实现复合材料与金属板交替铺层，对复合材料切割成哑铃试件，一次性加工多个哑铃试件，在进行湿热老化的时候，对两端进行密封处理，避免了两端老化，从而在拉伸测试过程中避免了两端夹持部分的脱落，还提升了样件加工效率。
