Title
(EN) USE OF A COPOLYAMIDE COMPOSITION AS A MATRIX OF FILLER MATERIAL WITH GLASS FIBRES HAVING A CIRCULAR CROSS SECTION FOR LIMITING WARPING
(FR) UTILISATION D'UNE COMPOSITION DE COPOLYAMIDE COMME MATRICE DE MATERIAU CHARGE AVEC DES FIBRES DE VERRE A SECTION CIRCULAIRE POUR LIMITER LE GAUCHISSEMENT
Abstract
(EN)
The invention relates to the use of a composition comprising at least one semi-crystalline copolyamide A/X1Y in which: - A is a repeat unit obtained from the polycondensation of at least one C6 to C12 lactam, or at least one repeat unit XY obtained from the polycondensation of at least one aliphatic C4 to C18 diamine (X), and of at least one aliphatic C6 to C18, in particular C6 to C12, dicarboxylic acid (Y), - X1Y is a repeat unit obtained from the polycondensation of a diamine (X1) chosen from an arylamine, a cycloaliphatic diamine and a branched aliphatic diamine and of at least one aliphatic dicarboxylic acid (Y) identical to that of the unit XY, the A/X1Y weight ratio being from 60/40 to 95/5, glass fibres having a circular cross section, and optionally at least one impact modifier and/or at least one additive, for limiting warping while at the same time maintaining the cycle time of the obtained composition suitable for processing thereof, in particular by injection moulding.
(FR)
L'invention concerne l'utilisation d'une composition comprenant au moins un copolyamide A/X1Y semi-cristallin dans lequel : - A est un motif répétitif obtenu à partir de la polycondensation d'au moins un lactame en C6 à C12, ou d'au moins un motif répétitif XY obtenu à partir de la polycondensation d'au moins une diamine aliphatique (X) en C4 à C18, et d'au moins un acide dicarboxylique aliphatique (Y) en C6 à C18, en particulier en C6 à C12, - X1Y est un motif répétitif obtenu à partir de la polycondensation d'une diamine (X1) choisie parmi une arylamine, une diamine cycloaliphatique et une diamine aliphatique ramifiée, et d'au moins un acide dicarboxylique aliphatique (Y) identique à celui du motif XY, le ratio en poids A/X1Y étant compris de 60/40 à 95/5, des fibres de verre à section circulaire, et optionnellement au moins un modifiant choc et/ou au moins un additif, pour limiter le gauchissement tout en gardant le temps de cycle de la composition obtenue adapté à sa mise en œuvre, en particulier par injection.
