Provided are a two-component curable composition, for manufacture of a thermoplastic polyurethane resin, that exhibits low mixing viscosity and high glass transition temperature after curing, a thermoplastic polyurethane resin that is a cured product thereof, and a fiber-reinforced resin including the thermoplastic polyurethane resin.
The two-component curable composition for manufacture of a thermoplastic polyurethane resin is a two-component curable composition including a polyol component including a diol (A) and a polyisocyanate component including a diisocyanate (B). The diol (A) includes a diol (A-1) having an aromatic ring and having a molecular weight of 200 to 700 and a diol (A-2) having no aromatic ring and having a molecular weight of 500 or less. The ratio ((A-1)/((A-1)+(A-2))) of the mass of the diol (A-1) to the total mass of the diol (A-1) and the diol (A-2) is (10/100) to (75/100).
