Title:
FIBER-REINFORCED MOLDED ARTICLE AND FIBER-REINFORCED MOLDED ARTICLE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/181579
Kind Code:
A1
Abstract:
Provided is a fiber-reinforced molded article having a reduced weight. This fiber-reinforced molded article contains a matrix resin, reinforcing fibers, and hollow particles. The hollow particles are each provided with a shell containing a resin and a hollow part enclosed by the shell. The shell contains, as the resin, a polymer including not less than 80 parts by mass of crosslinkable monomer units in 100 parts by mass of the total monomer units. When an immersion test for the hollow particles is performed by adding 4mL of acetone to 0.1 mg of the hollow particles in a 25°C-environment, shaking the mixture for 10 minutes at a shaking speed of 100 rpm, and leaving the mixture still for 48 hours, the amount of hollow particles that precipitate in acetone is less than 5 mass%.
