  • Patent number: 7005185
    Abstract: An epoxy composition includes an epoxy resin, a latent curing agent, and a catalyst. The composition includes two epoxide groups per molecule, and the latent curing agent is preferably a dicyanopolyamide, and most preferably dicyandiamide. The catalyst includes 2,4-toluene bis dimethyl urea, preferably in a concentration exceeding 70% by weight. The composition can be used in prepregs. The relative concentrations of the epoxy resin, curing agent, and catalyst are selected to achieve desired properties, including specific curing times and temperatures, and glass transition temperatures that enable a cured resin composition to be removed from a mold after being heated to its curing temperature, without being cooled. Exemplary formulations have reduced cure times, at both high and low curing temperatures, as compared to prior art formulations.

  • Patent number: 6998011
    Abstract: In the preparation of an improved adhesive composition, an epoxy-based prepolymer is obtained by the reaction of one or more epoxy resins with amino-terminated polyethers and/or carboxyl-terminated butadiene-nitrile rubbers. In one embodiment of the invention, both a solid epoxy resin and a liquid epoxy resin, each of which is a diglycidyl ether of a polyphenol such as bisphenol A, are used. The epoxy-based prepolymer is mixed with an acrylate-terminated urethane resin (preferably, one based on a polyol having a number average molecular weight of at least about 400) and a heat-activated latent curing agent to make an adhesive composition which can be pumpable at room temperature. Curable adhesives capable of expansion to about 100% with high impact resistance after curing may be obtained by inclusion of expanding agents such as expandable microspheres.

  • Patent number: 6986948
    Abstract: A laminate formed from a first fiber-reinforced ply joined by a laminating resin composition to a second fiber-reinforced ply. The laminating resin composition is the cured residue of a polyester resin being end-terminated with an alkyl acrylate group and diluted with less than about 35 wt-% styrene. The first fiber-reinforced ply is laminated to the second fiber-reinforced ply with the laminating resin composition by coating a surface of the first ply with an adhesive composition. The coated first ply surface is joined with a surface of the second ply and the adhesive cured. In making the laminating resin composition, unreacted alkyl acrylate can be reacted with an epoxy to push the reaction to completion.
