Title
(DE) POLYAMIDBASIERTE HARZZUSAMMENSETZUNG MIT HERVORRAGENDEM ELASTIZITÄTSMODUL UND SCHLAGFESTIGKEIT
(EN) POLYAMIDE-BASED RESIN COMPOSITION HAVING EXCELLENT FLEXURAL MODULUS AND IMPACT STRENGTH
(FR) COMPOSITION DE RÉSINE À BASE DE POLYAMIDE AYANT UN EXCELLENT MODULE D'ÉLASTICITÉ EN FLEXION ET UNE EXCELLENTE RÉSISTANCE AU CHOC
Abstract
(EN)
Disclosed is a polyamide-based resin composition comprising (A) 20 to 60% by weight of an aliphatic polyamide resin having 16 to 24 carbon atoms, and (B) 40 to 80% by weight of a glass fiber having a fibrous shape and a ratio of a short axis to a long axis of 1:2 to 1:6 in cross section. The polyamide-based resin composition according to the present invention exhibits excellent flexural modulus and impact strength.

(FR)
Selon la présente invention, une composition de résine à base de polyamide comprend (A) 20 à 60 % en poids d'une résine polyamide aliphatique ayant 16 à 24 atomes de carbone et (B) 40 à 80 % en poids de fibre de verre qui se présente sous la forme de fibre et possède un rapport de petit axe à grand axe de section transversale de 1:2 à 1:6. La composition de résine à base de polyamide selon la présente invention présente un excellent module d'élasticité en flexion et une excellente résistance au choc.
