COMPOSITE MATERIALS COMPRISING A REINFORCING MATERIAL AND A STAR POLYAMIDE AS A THERMOPLASTIC MATRIX, THE PRECURSOR COMPOUND ARTICLE OF SAID MATERIALS AND THE PRODUCTS OBTAINED USING SAME |
摘要 |
The invention relates to a precursor article of a composite material comprising a polymer matrix and at least one reinforcing wire and/or fibres, said article comprising at least one reinforcing wire and/or fibres and at least one polymer matrix wire and/or fibres. The invention is characterised in that: said reinforcing wire and/or fibres are made from a reinforcing material and may comprise a thermoplastic polyamide part; said polymer matrix wire and/or fibres are made from thermoplastic polyamide; and the thermoplastic polyamide of said reinforcing wire and/or fibres and/or said polymer matrix wire and/or fibres comprise at least one polyamide with a star structure which contains: star macromolecular chains comprising one or more cores and at least three branches or three polyamide segments which are linked to the core; if necessary, linear polyamide macromolecular chains. |
