    摘要: The present invention concerns a process for the production of injection moulded glass fibre reinforced composites from extruded glass fibre reinforced pellets, said process comprising the following steps:
    (A) Providing:
    (a) Glass fibres (2) coated with a silane based sizing composition, said silane based sizing composition comprising at least one sizing reactive moiety, A1, A2, , (b)A thermoplastic matrix polycondensate (2) comprising a first matrix reactive moiety, B1, at a first end of the chain and a second matrix reactive moiety, B2, at a second end of the chain, ,
    (c) A salt (3) selected among an internal lubricant and a nucleating agent comprising a salt reactive moiety, C, capable of reacting with the at least one sizing reactive moiety, A1, A2, and/or with the first or second matrix reactive moiety, B1, B2, said salt reactive moiety, C, being selected among,
    • A metallic cation ,
    • An organic portion having a functionality, f = 1, with a reactive moiety selected among the anionic form of a carboxylic group or a hydroxyl group, and
    • An inorganic anion such as carbonate or sulphate,

    (B) Blending the glass fibres, thermoplastic matrix polycondensate, and salt;
    (C) Forming glass fibre reinforced pellets; and
    (D) Injection moulding a composite part with a composition comprising the reaction product of said glass fibres, thermoplastic matrix polycondesate and salt

    Characterized in that, the salt is added to a blend of thermoplastic matrix composite and glass fibres only after the first and/or second matrix reactive moieties, B1, B2, and the at least one sizing reactive moiety, A1, A2, are given time to react together at least partially.

    摘要: The present invention provides an impregnation system suitable for impregnating filaments continuously with an impregnating substance, said system may comprise an impregnation assembly comprising (a) at least one axial passageway for the filaments having an entrance end and an exit end and (b) at least one passageway for the impregnating substance having at least one inlet for the impregnating substance and at least two outlets for the impregnating substance leading into the passageway for the filaments via the outlets for the impregnating substance, wherein the passageway for the filaments has an oblong cross- section at the outlet point for the impregnating substance, and the at least two outlets for the impregnating substance have an oblong cross-section, and are disposed essentially opposite to each other, at the opposite widths of the passageway for the filaments. Thus, the present invention proposes an in-line system for manufacturing continuous fiber reinforced thermoplastic structure which comprises a simple device to provide strands in spread filaments form without using high friction or tension on the strand or filaments so as to ease the impregnation step and to allow higher line speeds and lower cycle times.
