Title (EN) FIBRE-REINFORCED COMPOSITE WITH REDUCED SURFACE WAVINESS
(FR) COMPOSITE RENFORCÉ PAR DES FIBRES AYANT UNE ONDULATION DE SURFACE RÉDUITE
Abstract:
(EN) The invention relates to fibre-reinforced composite (K) comprising (based on the total weight of the fibre-reinforced composite (K)): (A)≥50 wt.-% of at least one continuous fibrous reinforcement material; (B)<50 wt.-% of at least one substantially amorphous matrix polymer composition comprising (based on the total weight of the matrix polymer composition (B)): (B1) 60 to 80 wt.-% of at least one copolymer of styrene and/or α-methyl styrene and acrylonitrile having a number average molecular weight Mn of 30,000 to 100,000 g/mol; and (B2) 20 to 40 wt.-%of at least one copolymer of styrene, acrylonitrile, maleic anhydride and/or maleic acid having a number average molecular weight Mn of 30,000 to 100,000 g/mol; wherein the matrix polymer composition (B) has a glass transition temperature (Tg) of at least 100°C and a melt volume-flow rate (MVR (220/10) determined according to ISO 1133) of 10 to 90 mL/10 min.
(FR) La présente invention concerne un composite renforcé par des fibres (K) comprenant (sur la base de la masse totale du composite renforcé par des fibres (K)) : (A) ≥ 50 % en masse d'au moins un matériau de renforcement fibreux continu ; (B) < 50 % en masse d'au moins une composition de polymère à matrice sensiblement amorphe comprenant (sur la base de la masse totale de la composition de polymère à matrice (B)) : (B1) 60 à 80 % en masse d'au moins un copolymère de styrène et/ou d'α-méthylstyrène et d'acrylonitrile ayant une masse moléculaire moyenne en nombre Mn de 30 000 à 100 000 g/mol ; et (B2) 20 à 40 % en masse d'au moins un copolymère de styrène, d'acrylonitrile, d'anhydride maléique et/ou d'acide maléique ayant une masse moléculaire moyenne en nombre Mn de 30 000 à 100 000 g/mol ; la composition de polymère matriciel (B) ayant une température de transition vitreuse (Tg) d'au moins 100 °C et un indice de fluidité à chaud (MVR (220/10) déterminé selon la norme ISO 1133) de 10 à 90 mL/10 min.
