Fiber reinforced epoxy resin composites are produced using a specific epoxy resin system. The epoxy resin system contains at least one polyglycidyl ether of a polyphenol. The system also contains a hardener that contains a mixture of aminocyclohexanealkylamine and polyalkylene polyamine hardeners. The ratio of epoxy resin groups to amine hydrogen groups is from 1.05 to 1.50. The epoxy resin system contains a tertiary amine catalyst such as a tertiaryaminophenol, a benzyl tertiary amine or an imidazole compound.

Curable epoxy resin systems containing mixtures of amine hardeners and an excess of epoxide groups

Curable compositions including an epoxy resin, a hardener, and a block copolymer having a thermoset-philic block and a thermoset-phobic block, where the block copolymer is from 20 weight percent to 80 weight percent of the curable composition are described herein.

Curable compositions

A curable epoxy resin composition comprising (a) at least one epoxy resin; (b) at least one curing agent; and (c) at least one high molecular weight poly(propylene oxide) poiyol toughening agent; and a process for preparing the curable epoxy resin composition.

Toughening agent for epoxy resin compositions

The present invention relates to the production of amphiphilic copolymer networks, or co-networks, and to methods for preparing amphiphilic co-networks. Furthermore, the present invention relates to products and/or films made from the amphiphilic co-networks produced in accordance with the synthesis methods of the present invention. In one embodiment, the present invention is related to crosslinkable and/or polymerizable compositions that can be utilized to form amphiphilic co-networks, where such compositions are block copolymer compositions that are formed from the combination of at least one hydrophilic segment, at least one hydrophobic segment, and at least one crosslinkable and/or polymerizable segment. In yet another embodiment, the present invention relates to amphiphilic co-networks that are optically clear and highly oxyphilic.
