轻质金属/聚合物/金属夹层复合材料由于具有高强度、高刚度、高阻尼性、抗振动等多种性能，在汽车工业中得到了广泛的应用。然而，层状夹层在不同载荷下的成形潜力还没有得到很好的研究。本文研究了不同试件尺寸和芯层厚度的316L/PP-PE/316L夹层复合材料在两种不同尺寸和形状的平板冲头拉深成形中的成形性。可以说，冲头的几何形状和芯层厚度对三层夹层的成形行为有很大的影响。对结果进行了摄影测量和金相分析。2012年，Politechnika Wroclawska。出版：Elsevier Urban&Partner Sp.动物园。版权所有。
Due to the wide range of different properties - such as high strength, stiffness, high damping capacity, vibration resistance and the lightweight - metal/polymer/metal sandwich composites find their application as various body-parts in the automotive industry. Nevertheless the forming potential of layered sandwiches under different loading is not well studied. In this research the formability of 316L/PP-PE/316L sandwich composites with different sample size and core thickness was studied for the deep drawing process using two flat punches of different size and shape. It could be stated that the forming behaviour of the three layered sandwiches is strongly influenced by the geometry of the punch and the core thickness. The results were analysed photogrammetrically and metallographically. (C) 2012 Politechnika Wroclawska. Published by Elsevier Urban & Partner Sp. zoo. All rights reserved.
