Title:
FIBER-REINFORCED POLYAMIDE RESIN COMPOSITION, MOLDED ARTICLE, SLIDING MEMBER, GEAR, WORM WHEEL, AND METHOD FOR MANUFACTURING THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/014544
Kind Code:
A1
Abstract:
The fiber-reinforced polyamide resin composition of the present invention contains a crystalline polyamide (A1) and glass fibers (B1), wherein: the formic acid-relative viscosity of the fiber-reinforced polyamide resin composition is 90 or more; when the fiber-reinforced polyamide resin composition is dissolved in formic acid, the insoluble content is 105 mass% or more with respect to the ash content of the fiber-reinforced polyamide resin composition; and, in the glass fibers (B1) contained in the fiber-reinforced polyamide resin composition, the ratio of glass fibers having a fiber length of 250 μm or less is 55% or less.
