Is it feasible to engineer a means of recovering lengths of continuous thermoplastic tapes from end-of-life parts by peeling individual layers under controlled conditions?
The objectives of the six month Feasibility study are to:
– Instrument a simplified peel tester with controlled heating for thermoplastic tape separation
– Establish the conditions (eg. temperature, force, speed) required to successfully peel a layer of continuous thermoplastic tape from a simple consolidated structure
– Determine the most appropriate metrological technique to assess the viability of recovered material (in terms of waviness, matrix distribution, defects)
– Attempt basic re-processing of peeled pre-pregs and determine composite properties relative to virgin parts
– Provide a framework and initial data for a core project addressing the automated circular manufacturing of thermoplastic composites
This project will explore means of recovering continuous thermoplastic prepreg from end-of-life parts by a controlled thermal peeling process in such a way as to make the peeled plies re-useable in new parts with minimal post-processing.
