Abstract[English]
A thermoplastic composition includes: a) from about 30 wt% to about 85 wt% of a polyamide resin; b) from about 1 wt% to about 25 wt% of a polycarbonate-siloxane copolymer; c) from about 5 wt% to about 40 wt% of a glass fiber; and d) a carbon filler component including d1) from greater than 0.1 wt% to less than 1 wt% carbon fiber, d2) from greater 1 wt% to less than 5 wt% carbon black, or d3) from greater than 1 wt% to less than 5 wt% multi-wall carbon nanotubes (MWCNTs). The composition exhibits a percent Absorbed Power measured in Transmission mode of at least 70% when observed according to a Free Space method at a frequency of 77 GHz. The composition exhibits an ε' of at least 5 and an ε" of no more than 4, wherein ε' and ε" are evaluated according to a Free Space Method.[French]
Une composition thermoplastique selon l'invention comprend : a) d'environ 30% en poids à environ 85% en poids d'une résine de polyamide; b) d'environ 1% en poids à environ 25% en poids d'un copolymère de polycarbonate-siloxane; c) d'environ 5% en poids à environ 40% en poids d'une fibre de verre; et d) un composant de charge de carbone comprenant d1) de plus de 0,1% en poids à moins de 1% en poids de fibre de carbone, d2) de plus de 1% en poids à moins de 5% en poids de noir de carbone, ou d3) de plus de 1% en poids à moins de 5% en poids de nanotubes de carbone à parois multiples (MWCNT). La composition présente un pourcentage de puissance absorbée mesuré en mode transmission d'au moins 70% lorsqu'elle est observée selon une méthode en espace libre à une fréquence de 77 GHz. La composition présente un ε' d'au moins 5 et un ε" inférieur ou égal à 4, ε' et ε" étant évalués selon une méthode en espace libre.
