Abstract
(EN)
Provided is a molded resin object capable of having a heightened flexural modulus. This molded resin object comprises a urethane resin, long reinforcing fibers, an inorganic filler having an average particle diameter of 1 μm or larger, and fine inorganic particles having an average particle diameter of 200 nm or smaller, the content of the fine inorganic particles being 0.06-3.00 parts by weight per 100 parts by weight of the urethane resin.
(FR)
L'invention concerne un objet en résinem moulée pouvant présenter un module d'élasticité en flexion accru. Cet objet en résine moulée comprend une résine d'uréthane, de longues fibres de renforcement, une charge inorganique ayant un diamètre moyen de particule supérieur ou égal à 1 µm, et de fines particules inorganiques ayant un diamètre de particule moyen inférieur ou égal à 200 nm, la teneur des fines particules inorganiques étant de 0,06 à 3,00 parties en poids pour 100 parties en poids de la résine d'uréthane.
(JA)
