Pre-coating processing method and pre-coating processing system for fiber-reinforced thermoplastic member

Abstract

The purpose of the present disclosure is to provide a pre-coating processing method and a pre-coating processing system (1) for fiber-reinforced thermoplastic member, which can achieve the coating adherence required in the field of aircraft. In a pre-coating processing method according to the present disclosure, a to-be-coated surface of a fiber-reinforced thermoplastic plastic member (2) is subjected to an activation treatment: in which the to-be-coated surface is activated under a condition such that the surface free energy of the to-be-coated surface immediately after the activation treatment reaches at least 70 mJ/m2; and in which the to-be-coated surface is heated to a temperature at which the modulus of elasticity of the to-be-coated surface becomes lower than that at normal temperature.
