Organic sheets are multi-layer thermoplastic composites used for semi-structural and structural applications in the automotive and aerospace industry. The organic sheets are produced in a continuous manner which enables high throughput to reduce production costs. However, the cutting of the blanks used to manufacture the final shape produces a large quantity of production offcuts. Current recycling strategies for these offcuts consist in shredding the material to produce chips, fragments or powders, which can be used respectively for thermoforming, thermoplastic sheet moulding compound or reinforced injection moulding. In any case, the shredding step leads to the loss of fibre length and orientation and thus to the loss of the mechanical properties of the composites. In this context, a proof of concept has been conducted and has demonstrated that the mechanical properties of the offcuts can be preserved through recycling by using a three-step process to separate the impregnated reinforcement layers. The process consists in (1) creating a notch in the thickness of the organic sheet by milling, which lets one single layer uncut, (2) impacting one of the two sides of the notch to initiate an interlaminar crack and (3) propagate the crack until the single layer is separated. The recovered patches could be used for example in Pick-and-Place-processes. In the present work, various notch geometries and post-impact loading kinematics have been investigated in order to better understand the crack initiation mechanisms and to increase the reproducibility and efficiency of the process. The conducted work enabled to identify the most suitable conditions for proper and reproducible interlaminar crack initiations. Furthermore, crack extensions up to 50 mm in length were obtained in the developed test setup, demonstrating that patches in industrial relevant dimensions can be produced with the investigated process.
