Abstract:
Provided are a curable resin composition capable of providing excellent heat resistance and toughness for a cured product, in which these physical properties are less deteriorated even in a case of being exposed to humidity and heat conditions, and a cured product, a fiber reinforced composite material, and a molded article thereof. The curable resin composition includes an epoxy resin and a curing agent, in which the epoxy resin is an epoxy resin obtained by the polyglycidyl-etherification of a phenol novolac resin. The phenol novolac resin contains bisphenol F having different binding sites, and in the bisphenol F components, the content of the [o, p′] conjugate is in a range of 30% to 45% relative to the total of the [o, p′] conjugate+the [o, o′] conjugate+the [p, p′] conjugate in terms of the area ratio according to a liquid chromatography measurement.
