Abstract[English]
Thermoplastic compositions include: at least one polyamide resin; at least about 30 wt% of a reinforcing fiber; and an impact modifier component including at least one impact modifier having a glass transition temperature (Tg) of about -30 degrees Celsius (°C) or lower. The reinforcing fiber has a fiber length of at least about 10 millimeters (mm). The thermoplastic composition has a notched Izod impact strength of at least 300 Joules per meter (J/m) at -40 °C and a multi-axial impact energy of at least 15 J at -40 °C. Methods of forming a pelletized thermoplastic composition, a plurality of thermoplastic pellets, and a composition including the plurality of thermoplastic pellets are also described.[French]
Des compositions thermoplastiques comportent : au moins une résine polyamide ; au moins environ 30 % en poids d'une fibre de renforcement ; et un composant antichoc comportant au moins un antichoc présentant une température de transition vitreuse (Tg) d'environ -30 degrés Celsius (°C) ou moins. La fibre de renforcement présente une longueur de fibre d'au moins environ 10 millimètres (mm). La composition thermoplastique présente une résistance au choc Izod sur éprouvette entaillée d'au moins 300 Joules par mètre (J/m) à -40 °C et une énergie au choc multiaxial d'au moins 15 J à -40 °C. Des procédés de formation d'une composition thermoplastique en granulés, une pluralité de granulés thermoplastiques, et une composition comportant la pluralité de granulés thermoplastiques sont également décrits.
