Title:
FIBER-REINFORCED RESIN MATERIAL, WOUND BODY, MOLDED ARTICLE, AND PRODUCTION METHOD FOR FIBER-REINFORCED RESIN MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/174871
Kind Code:
A1
Abstract:
Provided are: a fiber-reinforced resin material that suppresses perforation and damage in a film thereof, by having a polyamide resin, such as MXD6, used therein in a molten state and impregnating continuously-reinforced fibers; a wound body; a molded article; and a production method for the fiber-reinforced resin material. This fiber-reinforced resin material is in the form of film and is obtained by impregnating, with a polyamide resin composition, continuous reinforced fibers arranged side by side in at least one direction. The polyamide resin composition contains: a polyamide resin (A) including diamine-derived constituent units and dicarboxylic acid-derived constituent units, 70 mol% or more of the diamine-derived constituent units being derived from meta-xylylene diamine, and 70 mol% or more of the dicarboxylic acid-derived constituent units being derived from adipic acid; and a polyamide resin (B) other than the polyamide resin (A). The polyamide resin composition has a melt tension of 1 mN or more and a melt viscosity of 250 Pa·s or more.
