Appl. No.:

11/127843

Inventors:

Scott Lucas - Mesa AZ, US

International Classification:

B32B 3/12

US Classification:

428117000, 442104000, 442172000, 442179000

Abstract:

Prepreg compositions comprised of fibers and a prepreg resin, comprising a thermosetting resin, a curing agent, and a plurality of thermoplastic polymers, in which greater than 10% of each of the thermoplastic polymers are soluble in the prepreg resin, are useful for making composite materials. In preferred embodiments, the prepreg compositions are used as self-adhesive prepregs for making honeycomb structures useful for various high performance applications.

B32B 2704

US Classification:

525113

Abstract:

A curable composition and a method of making it comprises reacting in the presence of a catalyst epoxy resin(s) having at least 0. 05% by weight of epoxy resin oligomer with a solid rubber which is swellable or soluble in the reaction mixture and possessing at least 1% by weight of reactive groups, in a rubber:epoxy resin(s) weight ratio of between 1:1 and 1:20, wherein said epoxy resin(s) comprises (a) at least one epoxy resin having an epoxy functionality of greater than three and (b) at least one second epoxy resin having a functionality of greater than one but not more than three; heating to effect the reaction, cooling to substantially ambient temperature, and adding any remaining portion of epoxy resin and curing agent(s).

C08L 6302

US Classification:

4282974

Abstract:

A shaped article optionally containing a prepreg, or a composite derived from the shaped article with the prepreg, is prepared from a curable composition derived from the reaction in the presence of a catalyst of epoxy resin having at least 0. 05% by weight of an epoxy resin oligomer with a solid rubber possessing at least 1% by weight of reactive groups and which is swellable or soluble in the reaction mixture, in a rubber epoxy resin weight ratio between 1:1 to 1:20, wherein said epoxy resin comprises (a) at least one first epoxy resin having an epoxy functionality of greater than three and (b) at least one second epoxy resin having a functionality of greater than one to three.
