Compact High-Power Electronic Components

Triton Systems, Inc. proposes to design and develop a lightweight hatch/scuttle using a combination of advanced hybrid metal/polymer matrix composites, fire resistant polymer, and electro-magnetic interference (EMI) shielding polymer for the DDG 51 surfacecombatant. This combination of materials and processes enables the fabrication of a hatch/scuttle that meets the major design criteria of damage tolerance, EMI shielding, fire resistance, dimensional stability, low weight, low maintenance, and low cost.The hybrid metal/polymer composite is a structure that allows a direct transition from metal matrix composite to polymer matrix composite with efficient load transfer. In addition, the structure allows the co-mingling of metal matrix composite withpolymer matrix composite in a unified structure, enhancing damage tolerance and EMI shielding. This approach also allows the co-casting of all of the closure, hinge and sealing fixtures simultaneously, reducing cost. Triton's InstaShield¿ polymer will beused for all external gluing, such as gaskets and seals. InstaShield¿ is a new conductive resin system that is formulated to high performance EMI shielding specifications, both for advanced composite laminations and adhesive applications.The compositehatch/scuttle proposed for development on this program is expected to have a direct impact on the DDG 51 ship by lightening the hatches and scuttles and reducing maintenance costs. Additional near term Navy applications include the DD21 surface combatantfor the 21st century and retrofit onto other naval vessels requiring lower maintenance costs and lighter hatches. Commercial applications include hatches, scuttles and doors for commercial cargo vessels, and commercial cruise liners.Additional applications include missile casing end fittings, space truss tube end fittings, bicycle frame fittings, automobile frames, bodies and joints, drive shaft end fittings, propeller hub assemblies and airframe components of all kinds.
