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.

Curable resin composition and fiber reinforced resin matrix composite material

A laminar pre-preg of fibre-reinforced curable composite material. The pre-preg includes at least one layer of reinforcing fibres impregnated with a curable resin containing one or more curable thermosetting resin(s) and at least one liquid curative, wherein the curable resin exhibits a cure conversion of at least 95% when cured at a cure temperature in the range of from about 100&#xb0; C. to about 160&#xb0; C. and the cure cycle has a duration of no more than 10 minutes, and the glass transition temperature (Tg) of the curable resin when cured is in the range of from about 130&#xb0; C. to about 165&#xb0; C.

Fast-cure pre-preg

Disclosed herein is an epoxy resin compositions comprising an epoxy component and a curing agent component, wherein the curing agent component is at least an aminoalkylimidazole curing agent, and wherein the epoxy component and the curing agent component react together at a temperature of about 100&#xb0; C. to about 130&#xb0; C. to form a substantially cured reaction product in about 10 minutes or less. Further disclosed are composite products formed from such epoxy resin compositions.

Fast cure epoxy resin compositions

A curable resin composition containing: (a) at least one resin; and (b) curative selected from the group consisting of (i) a mixture of at least one low temperature curative and at least one high temperature curative or (ii) a curative that has a low temperature curative part and a high temperature curative part wherein the amount of the low temperature curative is sufficient to cause enough resin-curative addition reaction to effect B-staging in the full resin-curative formulation, the amount of the high temperature curative is sufficient to cause the resin to cure catalytically but insufficient to cause resin-curative addition reaction in the final cure, and the ratio of the resin (a) to the curative (b) is greater than or equal to about 5. The present composition may be used to make prepregs for automotive or aerospace application.
