Advanced Structural Development for Naval Hovercraft Ramps
Materials Sciences Corporation (MSC), of Horsham, Pennsylvania, in partnership with Seemann Composites Inc. (SCI), of Gulfport, Mississippi have designed, fabricated and proof-tested a lightweight, durable, corrosion-resistant composite stern ramp for the Navy’s Landing Craft Air Cushion Vehicle (LCAC-43). Successful proof-testing of the first-article stern ramp prototype has demonstrated the superior durability and structural performance of the composite solution while realizing weight savings projections of approximately 40% over in-service aluminum ramps. The MSC/SCI team is currently in the process of leveraging this successful demonstration in the development of a composite bow ramp structural solution. Pending the successful demonstration of a bow ramp prototype, Navy PMS-377 projections indicate the potential for significant operational life-cycle cost savings for the LCAC100 fleet through the implementation of composite vehicle ramps.
Surface Combatant Composite Mid-Frequency Sonar Dome (MSC P4192)
The low cost, mid-frequency, composite sonar dome being designed for the DDG-1000 class ship is fabricated using state of the art, out-of-autoclave composite from a material system qualified for Navy Structures. The design and qualification of the dome will be done in accordance with Navy approved procedures by the Materials Sciences Corporation, a composites development company with capabilities in design, analysis, and testing of high-performance structures for military and civilian use. MSC's manufacturing partner, Seemann Composites Inc, has a proven track record of delivering large-scale Naval components fabricated using the Seemann Composites Resin Infusion Molding Process (SCRIMP). A phase 3 SBIR project is being considered to have the MSC / SCI team produce a sonar dome to be used on the DDG-1002 with a potential option to produce spares for DDG-1000 and 1001. When completed, the product will outperform hand-layup composite.
Sinking Hose System for Amphibious Bulk Liquid Transfer System (ABLTS)
The sinking hose system for the Amphibious Bulk Liquid Transfer System (ABLTS) is a high-pressure collapsible hose which will remain stable on the seafloor when filled with fuel yet is “lay-flat” so that it can be stored in containers. Materials Sciences Corporation, a small business that performs design, analysis, testing, product development, and low rate production of fiber reinforced materials and products, applies a legacy of analytical mechanics to create and produce new products and services with high-tech materials. This product replaces the floating, low-pressure ABLTS hose with a 500 psi, sea-floor hose that is still deployed from lighterage vessels. MSC has demonstrated feasibility of integrating heavy layers while maintaining flexibility and the exposure of the materials to water and fuel.
