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.
The Improved Skirt System for Air Cushion Vehicles (ACV) uses a new elastomer coating technique to create a strong, abrasion resistant textile to withstand extreme physical requirements. Materials Sciences LLC (MSC) is an engineering and manufacturing company focused on applying knowledge of material mechanics to create unique solutions. The skirt system for the Ship-to-Shore Connector (SSC) sees perhaps the most extreme punishment of any coated fabric, resulting in high replacement costs and down-time. MSC’s approach uses an alternative coating method which enables high-performance textile designs that are incompatible with conventional techniques. The product has shown superior performance to the existing product. MSC is currently tooling up production capabilities to support the SSC integrator as a new material supplier for the skirt fabricator.
