(EN) SEMIAROMATIC POLYAMIDE COMPOSITE ARTICLE AND PROCESSES FOR ITS PREPARATION
(FR) ARTICLE COMPOSITE POLYAMIDE SEMIAROMATIQUE ET SES PROCÉDÉS DE PRÉPARATION
Abrégé
(EN)
A semiaromatic polyamide composite article comprising a first component comprising a fiber-reinforced material comprising a polyamide composition and reinforcing fibers and having a tensile modulus of at least about 16 GPa as measured by ISO method 527-2:1993 at a rate of 5 mm/min on test specimens having a thickness of 4 mm, a second component comprising a polyamide composition, and an optional tie layer therebetween. The polyamide composition of first component and/or the second component is a semiaromatic polyamide compositions. The second component is prepared by injection molding and/or injection-compression molding the semiaromatic polyamide composition onto the first component.
(FR)
L'invention concerne un article composite polyamide semiaromatique comprenant un premier composant comprenant un matériau renforcé par des fibres, ledit matériau comprenant une composition polyamide et des fibres renforçantes et ayant un module de traction supérieur ou égal à environ 16 GPa, mesuré par le procédé ISO 527-2:1993 à une vitesse de 5 mm/min sur des échantillons d'une épaisseur de 4 mm, un second composant comprenant une composition polyamide et une éventuelle couche de liaison entre eux. La composition polyamide du premier composant et/ou du second composant est une composition polyamide semiaromatique. Le second composant est préparé par moulage par injection et/ou moulage par injection-compression de la composition polyamide semiaromatique sur le premier composant.
