Recycling of Fiber-Metal Laminates
Fiber metal laminates provide superior mechanical properties over conventional metal alloys. However, they show a very poor recyclability due to its composite nature. Unique recycling technique is developed to recycle both the glass fiber and the aluminum alloy. The process consists of a thermal delamination and an alloy refining step. In this paper, two fiber metal laminates were presented for their thermal delamination behavior and metal recyclability: Lacomet and GLARE. The results indicate that the thermal delamination is robust and energy-efficient, and the aluminum alloy has very high recovery rate and can be used in its original applications. The recovered glass fiber can be re-used in similar or non-critical applications.
