Abstract

PURPOSE:To homogenize strength, etc., of the subject fiber by dipping stranded reinforcing fiber in a solution of a powdery phenolic resin dispersed therein, drying the fiber, evaporating and removing only a solvent. CONSTITUTION:For example, a powdery phenolic resin having 200 mesh average particle diameter is added to a styrene monomer solution and stirred to provide a dispersion. A glass fiber roving is then dipped in the aforementioned dispersion to permeate the dispersion therein. The resultant roving is subsequently dried to evaporate a solvent and afford the objective fiber.

However, since the raw material liquid phenol resin generally has a high viscosity higher than IOP, it is difficult to uniformly impregnate stranded glass fibers, and even if the immersion time is long, the resin impregnation state will not be dense. There was a problem that it was difficult to obtain uniform product strength.

Table 1 [Effects] As explained above, in this invention, even if it is a resin that is difficult to impregnate, it can be impregnated without affecting the properties of the resin because it is dispersed in a solution that does not affect the Mi concentration of the resin. It can be done uniformly, and if the solvent is volatilized and removed, the influence of this solvent is eliminated, so the matrix strength of the molded product is not affected, which makes it possible to mold FRP with uniform strength and excellent strength. have an effect.
