ABSTRACT:
Curable epoxy resin compositions, preferably solvent-free, wherein a fluorene amine curative is partially melt dissolved and partially dispersed as a solid in at least one aromatic polyepoxide. The compositions provide prepregs which exhibit tack with surprisingly good shelf life properties. Cured composites comprising the prepregs are also provided. The cured composites exhibit little resin migration and glass transition temperatures that are comparable to those of cured neat resins.
