    Abstract: The invention relates to a method for producing a thermoplastic fibre composite containing a thermoplastic moulding compound (A) as a polymer-matrix (M), reinforcement fibres (B), and optionally additive (C). Said method comprises the following steps: i) flat structures (F) made from reinforcing fibres (B) treated with a silane sizing material are provided, ii) the flat structures (F) are placed in a thermoplastic molding compound (A) which comprises at least 0.3 mol %, with respect to components (A), of a chemically reactive functionality, iii) chemically reactive groups of the thermoplastic molding compound (A) are reacted in the polymer matrix (M) with the polar groups of the treated reinforcing fibres (B), iv) the at least one additive (C) is optionally incorporated v) cooling. Said method is particularly suitable for producing fibrous composites.
