Abstract Wire mesh interlayers are introduced to fabricate high interface strength metal-polymer-metal sandwich panels. While resistance welding is used to join metal sheets to wire mesh at predesignated spots, vacuum hot pressing is used to infuse polymer into the wire mesh. Peel strength for fabricated sandwich panels is seen to be around 300% higher than that for adhesive joints reported in literature. Since, interface strength is achieved from welding and mechanical interlocking, it does not degrade in presence of moisture. Uni-axial tensile tests are used to characterize strength and elongation of individual layers and fabricated sandwich panels. Interface strength is characterized using peel and double lap shear tests. V-bending and stretch forming experiments are used to demonstrate formability of the developed sandwich panels. The presented method is an attractive alternative to use of adhesives for joining of metals to polymers.

一种在夹层板中连接金属和聚合物片材以显着提高界面强度的新方法

摘要 引入金属丝网夹层来制造高界面强度的金属-聚合物-金属夹层板。电阻焊用于在预先指定的位置将金属板连接到金属丝网，而真空热压用于将聚合物注入金属丝网。制造夹芯板的剥离强度比文献中报道的粘合接头的剥离强度高约 300%。由于界面强度是通过焊接和机械互锁实现的，因此在存在水分的情况下不会降低。单轴拉伸试验用于表征单层和夹心板的强度和伸长率。使用剥离和双搭接剪切试验表征界面强度。V 形弯曲和拉伸成型实验用于证明开发的夹层板的成型性。
