Title:
CARBON FIBER REINFORCED COMPOSITE AND PRODUCTION METHOD OF CARBON FIBER REINFORCED COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2023/048260
Kind Code:
A1
Abstract:
A carbon fiber reinforced composite and a production method of the carbon fiber reinforced composite are provided which can shorten curing time and achieve high mechanical strength while reducing bleeding of the resin. The carbon fiber reinforced composite contains carbon fibers, an epoxy resin, a curing agent and a thermoplastic resin, wherein the mixture of the epoxy resin and the thermoplastic resin is such that ratio (viscosity at 30°C/viscosity 90°C) of the viscosity at 30°C and the viscosity at 90°C is less than 100.
