Abstract:
To provide a resin composition, wherein the resin composition is excellent in impregnation into a reinforcing fiber sheet as it contains a polyamide having a low viscosity number; wherein the resin composition can be molded into a film, a fiber, etc., even though it contains a polyamide having a low viscosity number; and wherein the resin composition can produce a fiber-reinforced molded product having excellent impact resistance; a molded product and a method for its production; and a fiber-reinforced molded product having excellent impact resistance and a method for its production.
A resin composition comprising: a polyamide having a viscosity number of from 100 to 170 determined by a method specified in ISO 307: 2007; and a melt-processable fluororesin having at least one type of a functional group selected from the group consisting of a carbonyl group-containing group, a hydroxy group, an epoxy group and an isocyanate group, and having a melting point of from 100 to 325° C.
