Circularity-engineering approach value-retention high-performance thermoplastic Project Details

Abstract

The aerospace industry encounters significant challenges in recycling end-of-use (EoU) or scrap composite materials, as conventional methods frequently degrade critical physical properties, including fiber length, orientation, and part size. This necessitates the development of a circularity approach capable of recovering and reusing these materials in high-performance applications. A central challenge lies in effectively separating fiber layers from the matrix without causing substantial damage, thereby enabling the recovered layers to be repurposed as patches for repairing damaged aerospace composite structures or for fabricating tailored laminates. Initial research indicates the potential of power ultrasonics to facilitate value-retention processes for carbon and glass fiber composites. Power ultrasonics offer a mechanism for composite layer

separation through ultrasonic-assisted cutting, followed by the reconsolidation of these separated layers onto other components via ultrasonic bonding. This methodology comprises four distinct stages to achieve near-complete recovery of high-performance thermoplastic composites: ultrasonic-assisted pre-cracking, ultrasonic layer separation, layer characterization, and ultrasonic reconsolidation. This approach aims to enhance material circularity and sustainability within the aerospace sector.
