Abstract:
By having the ability to re-melt the matrix, thermoplastic carbon fibre reinforced polymers (CFRP) are
interesting candidates for recycling. A novel approach to separate thermoplastic CFRPs into fragments using electrodynamic fragmentation (EDF) is presented. The method was applied to a complex structural part which was made from unidirectional chopped tapes of 20 mm length (PEEK/AS4 55 Vol%) using a non-isothermal compression moulding cycle. The specimens made with chopped tapes were subsequently dissociated in a high voltage fragmentation lab unit. The ultimate load the parts made with recycled thermoplastic composites were comparable to the ones made from virgin chopped tapes with a reduction of only 17% of the maximal strength [1]. It was noted that smaller fragments considerably reduce the coefficient of variation of the ultimate strength
while lowering the mean value to a limited extend only.
