The present disclosure relates to a B-stageable epoxy adhesive composition and an article manufactured therefrom. The B-stageable epoxy adhesive composition comprises (A) 20% to 50% by weight of a first epoxy resin with an epoxide equivalent of 5000 g/eq or more; (B) 5% to 20% by weight of a second epoxy resin with an epoxide equivalent of 800 g/eq or less and having 2 to 4 epoxy functional groups; (C) 5% to 30% by weight of a carboxyl terminated polyester; (D) 5% to 15% by weight of a poly-isocyanate modified polyester; and (E) 0.1% to 0.5% by weight of a crosslinking agent containing 2 or more aziridine groups, all the content percentages are based on the total weight of the B-stageable epoxy adhesive composition. The B-stageable epoxy adhesive composition and the related products could be widely used as insulation protection for battery management, bus bar, transformers and other markets with a good balance between a high bonding strength and a high temperature resistance, and others.

Provided are a curable composition which is rapidly curable and which gives cured products with good heat resistance, a cured product thereof, a fiber-reinforced composite material, a fiber-reinforced resin-molded article, and a method for manufacturing the fiber-reinforced resin-molded article. Provided are a curable composition containing an epoxy resin (A), an aliphatic and/or alicyclic amine compound (B), and an imidazole compound (C), wherein the ratio H/E of the number of moles H of active hydrogen in the aliphatic and/or alicyclic amine compound (B) to the number of moles E of an epoxy group in the epoxy resin (A) is in the range of 0.2 to 0.9; a cured product thereof; a fiber-reinforced composite material; a fiber-reinforced resin-molded article; and a method for manufacturing the fiber-reinforced resin-molded article.
