摘要

Manufacturing a semi-finished textile product from carbon fibers obtained from a matrix material, comprises: (a) manufacturing a non-woven fabric composed of at least 10% carbon fibers and/or a fleece composed of at least 10% carbon fibers, where at least a portion of the fibers used for the manufacturing of the fabric or fleece, are waste fibers and/or recycling fibers; and (b) impregnating the non-woven fabric and/or fleece with a matrix material comprising thermoplastic material, thermoset materials and/or elastomers. Independent claims are included for: (1) the semi-finished textile product, preferably prepreg, comprising carbon fibers pre-impregnated with the matrix material; and (2) a carbon fiber reinforced composite material obtained by hardening or thermally deforming and optionally after compacting the semi-finished textile product.
