US Patent:

8008409, Aug 30, 2011

Filed:

Oct 6, 2009

Appl. No.:

12/573995

Inventors:

Tat Hung Tong - Bellbrook OH, US
David Martin Nickerson - Columbus OH, US

Assignee:

Cornerstone Research Group, Inc. - Dayton OH

International Classification:

C08F 283/00

US Classification:

525523

Abstract:

The currently disclosed device is a novel poly(azidoaminoether)-based energetic polymer utilizing a chemical design that possesses great versatility in tailoring properties such as endothermicity, oxygen balance, flexibility, toughness, and crystallinity. Furthermore, this new chemical design will also be compatible with current polyisocyanate curing chemistry. These attributes will give such novel polymers great potential in meeting the demands of a highly energetic, yet insensitive propellant binder. This material's tailorable mechanical properties and oxygen balance as well as its backwards compatibility with current diisocyanate crosslinking methods make this novel polymer an ideal energetic binder material for use in a variety of munition systems.

US Patent:

20100137554, Jun 3, 2010

Filed:

Nov 21, 2006

Appl. No.:

12/090460

Inventors:

Richard D. Hreha - Beavercreek OH, US
Benjamin J. Vining - Dayton OH, US
Robert M. Schueler - Centerville OH, US
David M. Nickerson - Xenia OH, US

International Classification:

C08G 63/44

US Classification:

528362

Abstract:

This disclosure covers a new methodology to produce high performance, high temperature, thermoset resins having shape memory characteristics based on cyanate ester resins. This methodology is based on pericyclic polycyclotrimerizations by utilizing a heretofore unknown polymerization mechanism based on equilibrium controlled condensation and cyclization. A mono-functional cyanate ester resin is reacted with at least one molecule terminated with a moiety containing an active hydrogen. One example of molecules with a moiety terminated with an active hydrogen are amine terminated dimethylsiloxane. The resulting compound is heated and reacted with a difunctional cyanate ester resin and cured. The Tg of the final Cyanate Ester SMP can be matched to specific requirements by adjusting the ratio of the previous said elements and/or the addition of other agents to adjust the physical properties of the final Cyanate Ester SMP.

Abstract:

Method embodiments for producing a fiber-reinforced epoxy composite comprise providing a mold defining a shape for a composite, applying a fiber reinforcement over the mold, covering the mold and fiber reinforcement thereon in a vacuum enclosure, performing a vacuum on the vacuum enclosure to produce a pressure gradient, insulating at least a portion of the vacuum enclosure with thermal insulation, infusing the fiber reinforcement with a reactive mixture of uncured epoxy resin and curing agent under vacuum conditions, wherein the reactive mixture of uncured epoxy resin and curing agent generates exothermic heat, and producing the fiber-reinforced epoxy composite having a glass transition temperature of at least about 100 C. by curing the fiber reinforcement infused with the reactive mixture of uncured epoxy resin and curing agent by utilizing the exothermically generated heat, wherein the curing is conducted inside the thermally insulated vacuum enclosure without utilization of an external heat source or an external radiation source.
