Document Type and Number:
WIPO Patent Application WO/2022/158559
Kind Code:
A1
Abstract:
A fiber-reinforced plastic molding material giving molded articles which, even when used at around the processing temperature, are inhibited from suffering spring back is provided without requiring the use of any super-engineering plastic, which is difficult to process. A thermoplastic resin composition according to the present invention includes one or more thermoplastic resins which, after having been infiltrated into a reinforcing fibrous base, become the matrix resin of a fiber-reinforced plastic, and is characterized in that the thermoplastic resins comprise a phenoxy resin as an essential component and account for 50 wt% or more of the whole resin composition and that when the resin composition is heated from room temperature to 280°C and then cooled to room temperature again with a rheometer, the resin composition has melt viscosities exceeding 10,000 Pa·s at the temperatures not higher than 220°C.
