金属聚合物夹层复合材料在航空航天和汽车工业中迅速取代了金属材料。其理想的机械性能，包括优异的疲劳和冲击强度，以及损伤容忍度，在不牺牲轻量化的情况下实现。在本研究中，采用直接粘合热辊粘合（WRB）技术制备了三层金属-聚合物-金属夹心复合材料，而不使用粘合剂。在不同厚度下（40%、50%、60%和75%）制作样品，并通过小冲孔试验将其与整体金属板的力学性能进行比较。结果表明，与单片材料相比，夹层复合材料的比强度分别提高了26%、20%和39%，厚度分别减少了50%、60%和75%。厚度减小60%和75%时，夹层复合材料的比断裂能分别比单片材料高7%和20%。结果表明，直接黏附WRB是一种很有前途的制造轻质金属-聚合物夹层复合板的技术。(C) 2016 Elsevier B.V.版权所有
Metal-polymer sandwich composites have been rapidly replacing metallic materials in aerospace and automobile industries. Their desirable mechanical properties including excellent fatigue and impact strength, as well as damage tolerance, are accomplished without sacrificing the benefit of lightweight. In this study, a three-layer metal-polymer-metal sandwich composite was fabricated using a direct adhesion warm roll bonding (WRB) technique without the use of an adhesive agent. Samples were made at various thickness reductions (40%, 50%, 60%, and 75%), and their mechanical properties were compared with the monolithic metallic sheet by performing a small punch test. The results showed significant improvements in the specific strengths of the sandwich composites compared with the monolithic material by 26%, 20%, and 39% at the thickness reductions of 50%, 60%, and 75%, respectively. The specific fracture energy of the sandwich composites at thickness reductions of 60% and 75% was higher than the monolithic material by 7% and 20%, respectively. The results showed that the direct adhesion WRB is a promising technique to fabricate a lightweight, metal-polymer sandwich composite panel. (C) 2016 Elsevier B.V. All rights reserved.
