摘要

PROBLEM TO BE SOLVED: To provide a bisphenol F-modified resol type phenol resin for a fiber-reinforced composite material which is excellent in curability, can reduce a diffusion amount of formaldehyde in the obtained cured product, and has good mechanical strength of the cured product; a resin composition and a cured product thereof; the fiber-reinforced composite material; a fiber-reinforced composite molded product; and a method for producing a bisphenol F-modified resol type phenol resin for fiber-reinforced composite material.SOLUTION: There are provided a bisphenol F-modified resol type phenol resin for fiber-reinforced composite material which is obtained by modifying a resol type phenol resin using aldehydes (A) and phenols (P) as raw materials with bisphenol F, and has a nonvolatile content of 55-85% and viscosity at 25°C measured according to JIS K 6910 of 200-2,000 mPa S; a method for producing the same; and a cured product containing the same.SELECTED DRAWING: None
