Abstract
A curable resin composition contains a curable resin that comprises at least one non-aromatic epoxy compound, at least one non-aromatic oxetane compound, or a mixture thereof, one or more curing agents selected from Lewis acid:Lewis base complexes, and a cure accelerating amount of one or more anhydride compounds. A method accelerating the cure of a curable resin composition, comprising adding a cure accelerating amount of one or more anhydride compounds to a curable resin composition comprising a curable resin that comprises at least one non-aromatic epoxy compound or non-aromatic oxetane compound and a curing agent that comprises one or more Lewis acid-base complexes. The composition and method are useful in making fiber reinforced resin matrix composite articles.
