Method for manufacturing fiber structure component i.e. carbon fiber component, in resin transfer molding tool in e.g. automobile industry, involves making viscosity of matrix material to be constant during introducing material in tool

摘要

The method involves inserting a fiber blank in a resin transfer molding tool (1), and closing lower and upper tool halves (1a, 1b). Low-viscosity matrix materials of two components are mixed with each other, where the viscosity of the mixed matrix material is less than 500 mPas. The low-viscosity matrix material is introduced into the tool, where the viscosity of the matrix material is constant during the introduction of the low-viscosity matrix material in the tool. Temperature is maintained to be constant during the introduction of the matrix material into the tool.
