Cross-section through a concept automotive seat by Johnson Controls and Camisma, manufactured with a combination of thermoforming and injection moulding. Sheets of continuous and unidirectional 12k carbon fibre and in-situ cast PA12 are combined with powder impregnated PA12 nonwoven recycled carbon fibre. They are placed into the mould and thermoformed, prior to back injection moulding of the rib structure using 30% long glass fibre filled PA12. Compared to a steel equivalent this structure saves 50% of the weight.
