Seemann Composites, Inc. (SCI), as the prime contractor, Materials Science Corporation (MSC) and McDonnell Douglas Phantom Works as subcontractors, propose to develop an advanced composite structure which will be significantly lighter, tougher and more reliable than previous hull structures and… More

Z-axis stitching offers improved performance and greatly increased damage tolerance for composite to composite joints (CTC). Z-axis stitching is employed in aircraft applications using complex, double-sided stitch machinery developed by NASA. This technology is very expensive, but offers increased… More

Composite structures for submarines require high strength and high fracture toughness to survive underwater shock blasts. These structures have historically been built using rubber-toughened epoxy pre-impregnated (pre-pregs) reinforcements. However, experience has shown that pre-pregs can be… More

The riverine requirements outlined by NAVSEA dictate that a composite material hull with innovative integral armor solutions and C4ISR may be required to meet the mission objectives. This response to the Phase I SBIR solicitation presents information on concepts for a Composite Armored Riverine… More

Current riverine craft are built in aluminum. Although aluminum is an obvious candidate material for a riverine operating environment, innovative solutions that deliver structural weight reduction to enable higher speeds, greater payload and increased survivability are always desired. Advanced… More
