Title

(EN) MATERIAL FOR SLIDE PART
(FR) MATERIAU DESTINE A UNE PARTIE COULISSANTE
Abstract
(EN)
To provide a material for sliding components, which is excellent in low warping property, high limiting PV value, low dynamic friction coefficient and wear resistance. This material is suitably used particularly for components such as gears, pulleys, cams and bearings of automobiles, and machines, and cable housing for supporting a cable (e.g., feed cable, signal cable, optical cable). The material for sliding components comprises a thermoplastic resin composition containing (A) a thermoplastic resin and (B) a glass fiber having a noncircular cross-section with the ratio of the long diameter to the short diameter in the cross-section perpendicular to the length direction being from 1.2 to 10. In the material for sliding components, based on the entire thermoplastic resin composition, the thermoplastic resin (A) accounts for 90 to 30 wt% and the glass fiber (B) having a noncircular cross-section with the ratio of the long diameter to the short diameter in the cross-section perpendicular to the length direction being from 1.2 to 10 accounts for 10 to 70 wt%.

(FR)
La présente invention concerne un matériau destiné à une partie coulissante qui présente un très faible gauchissement, une valeur photovoltaïque de limite supérieure, un faible coefficient de frottement dynamique et une résistance à l'abrasion, et dont l'utilisation convient particulièrement lorsqu'il est destiné à l'engrenage, la poulie, la came, le palier, etc. d'une automobile, d'une machine, etc., au logement pour câbles servant à supporter des câbles, tels un câble d'alimentation électrique, un câble de signal et un câble optique, etc. L'invention a trait à un matériau destiné à une partie coulissante qui se caractérise en ce qu'il comprend une composition de résine thermoplastique renfermant (A) une résine thermoplastique et (B) une fibre de verre pourvue d'une section non circulaire dans laquelle suivant la section perpendiculaire à la direction de la longueur, le rapport du grand axe sur le petit axe se situe dans une plage comprise entre 1,2 et 10. La composition du matériau destiné à la partie coulissante comprend, si l'on se base sur le poids total de la composition de résine thermoplastique, entre 90 et 30 % en poids de résine thermoplastique (A) et entre 10 et 70 % en poids de fibre de verre (B) pourvue d'une section non circulaire dans laquelle suivant la section perpendiculaire à la direction de la longueur, le rapport du grand axe sur le petit axe se trouve dans une plage comprise entre 1,2 et 10.
