Provided are: a curable composition that can be cured at low temperature in a short time regardless of the type of epoxy compound that is mixed therewith, and has a long pot life; an adhesive comprising said curable composition; a method for producing a fiber-reinforced composite material that uses the curable composition; and a fiber-reinforced composite material containing a matrix comprising the curable composition. Furthermore, the present invention provides a curing agent mixture composition that can be cured at low temperature and in a short time, and provides the curable composition with a long pot life. Furthermore, provided is a curing agent mixture composition that can be cured at low temperature and in a short time, and provides the curable composition with a long pot life. An epoxy compound (A) and an imidazole compound (B) having a specific structure are blended in with the curable composition. In addition, the imidazole compound (B) having a specific structure and at least one type of crosslinking agent (C) selected from the group comprising a polyvalent amide compound and a polyvalent carboxylic acid anhydride are blended in with the curing agent mixture composition.
本发明提供了:一种可固化组合物,无论与哪种环氧化合物混合,都能在短时间内低温固化,并具有较长的固化寿命;一种包含所述可固化组合物的粘合剂;一种使用该可固化组合物生产纤维增强复合材料的方法;以及一种含有包含该可固化组合物的基体的纤维增强复合材料。此外,本发明还提供了一种固化剂混合物组合物,可在低温和短时间内固化,并使固化组合物具有较长的固化寿命。此外,本发明还提供了一种固化剂混合物组合物,可在低温和短时间内固化,并使固化组合物具有较长的固化寿命。环氧化合物(A)和具有特定结构的咪唑化合物(B)与固化剂混合物混合。此外,具有特定结构的咪唑化合物(B)和至少一种从包括多价酰胺化合物和多价羧酸酐的组中选出的交联剂(C)也混入固化剂混合物中。
