High-performance aluminium foam sandwich prepared through friction stir welding

The aluminium foam sandwich (AFS), prepared through the traditional adhesive or brazing methods, usually exhibits a low flexural strength due to the poor combination among the face sheets and the aluminium foam core. In this work, a new method, named friction stir welding (FSW), was utilized to fabricate AFS. The results demonstrated that the joining of the face sheets and aluminium foam was achieved through the plasticized metal flow. In addition, the AFS prepared through FSW possessed high flexural strength and impact resistance, as well as good sound absorption and reduction performance. This demonstrated that the FSW was a good method to prepare AFS. (C) 2018 Elsevier B.V. All rights reserved.

通过传统的胶粘或钎焊方法制备的泡沫铝夹芯板（AFS），由于面板与泡沫铝芯之间结合不良，通常表现出较低的抗弯强度。在这项工作中，一种名为搅拌摩擦焊（FSW）的新方法被用于制造泡沫铝夹芯板。结果表明，面板和泡沫铝是通过塑化的金属流动实现连接的。此外，通过搅拌摩擦焊制备的泡沫铝夹芯板具有较高的抗弯强度和抗冲击性，以及良好的吸声和降噪性能。这表明搅拌摩擦焊是一种制备泡沫铝夹芯板的良好方法。（C）2018爱思唯尔有限公司。版权所有。
