▎ 摘　　要

NOVELTY - Production of article (10) involves preparing (i) component(s) (11,11') of a fiber-reinforced composite material comprising fibers of a polyamide (a) in a matrix of a polyamide (b), fibers and a matrix of the same polyamide in two different crystalline forms A and B, or fibers (12,12') and a matrix of the same polyamide in two forms A and B with different molecular weights, arranging (ii) the component(s) (11,11') inside a mold cavity, pre-heating (iii) and possibly thermoforming the component (11,11') in mold, injecting (iv) a molten polyamide (c) optionally loaded with a dispersed filler into the space of the cavity not occupied by the component (11,11'), and solidifying (v) the polyamide (c) to obtain a non-fiber-reinforced component (13) optionally loaded with dispersed filler and removing the obtained article from the mold. The polyamide (a) of the fibers has a high melting point than the polyamide (b) of the matrix. USE - Production of article (claimed). Uses include but are not limited to rear component of seat, bumper, air bag housing, toothbrush, etc. ADVANTAGE - The method enables production of article having high mechanical strength and excellent dimensional characteristics. DETAILED DESCRIPTION - Production of article comprising coupling of at least two polyamide-based components (20,21) including a component (13) made of a polyamide matrix optionally loaded with a filler dispersed in the matrix, and a component (11,11') made of a polyamide matrix reinforced with fibers made of a polyamide involves preparing (i) component(s) (11,11') of a fiber-reinforced composite material comprising fibers of a polyamide (a) in a matrix of a polyamide (b), fibers and a matrix of the same polyamide in two different crystalline forms A and B, or fibers (12,12') and a matrix of the same polyamide in two forms A and B with different molecular weights, arranging (ii) the component(s) (11,11') inside a mold cavity having a shape and/or a size so as not to be completely occupied by the component (11,11'), pre-heating (iii) and possibly thermoforming the component (11,11') in mold, injecting (iv) a molten polyamide (c) optionally loaded with a dispersed filler into the space of the cavity not occupied by the component (11,11'), and solidifying (v) the polyamide (c) to obtain a non-fiber-reinforced component (13) optionally loaded with dispersed filler and removing the obtained article from the mold. The polyamide (a) of the fibers has a high melting point than the polyamide (b) of the matrix. The process (ii) and process (iii) can be performed in any chronological order. An INDEPENDENT CLAIM is included for the article. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the article.
