Abstract (en)

[origin: WO2013004672A1] The invention relates to a method for laying up a strip (110) of fibres containing a thermoplastic polymer and for consolidating during laying of a component thus laid up, said method involving the steps consisting in: a. pre-consolidating a strip (115) through the pultrusion (120) of rovings (110) that have been pre-impregnated with a thermoplastic polymer through a die; b. storing said pre-consolidated strip in the form of a semifinished product; c. laying up said semifinished product on a ply (117) of the same kind, previously laid on a form (150) while pressing (165) said semifinished product (115) onto said ply (117) and heating the interface between the semifinished product and the ply (117) already laid to a temperature T capable of causing the semifinished product (115) to weld to said ply (117).
