5 BACKGROUND Half scale DDG Mast Composite Structures

6 ENABLES NEW TECHNOLOGY l Embedded Sensors l Planar Arrays l Low Observable Ship Signatures ENABLES NEW TECHNOLOGY l Embedded Sensors l Planar Arrays l Low Observable Ship Signatures SOLVES PROBLEMS l Sensor Performance –Blockage –False Targets –Sensor Downtime l Affordable Signature Control l Topside Weight Limitations l Life Cycle Costs –Sensors –PCMS SOLVES PROBLEMS l Sensor Performance –Blockage –False Targets –Sensor Downtime l Affordable Signature Control l Topside Weight Limitations l Life Cycle Costs –Sensors –PCMS ATD PAYOFFS

7 ADVANCED ENCLOSED MAST/SENSOR AEM/S

8 TAILORED MATERIAL SYSTEMS

9 Manufacturing Process Seemann Composite Resin Infusion Molding Process (SCRIMP): – Near Autoclave Laminate Quality At Shipyard Prices – Extremely Low Void Content Laminate – High Fiber to Resin Volume Ratio = High Strength to Weight

10 SCRIMP = Cost Effective Advanced Composite Structures

11 FABRICATING THE STRUCTURAL MAST

12 The AEM/S Experience – Fiber Reinforcement & Core Lay-up For A Deck Cloth Lay-up On Mold Cloth Lay-up On Core Core Laid On Cloth

13 The AEM/S Experience – Fiber Reinforcement & Core Lay-up For The Mast Cloth Lay-up In Full-Round Mold Panel Laminated & Mold Rotated Lay-up For Sixth Side Panel Ring Girder Installation Ring Girders Laminated In-Place Lower-Half Removed From Mold

14 The USS Radford AEM/S Mast Stepping Ceremony

15 AEM/S Fleet Transition to LPD 17 Advanced Composite Mast on USS Radford Transition LPD 17 Successful ONR Funded Advanced Technology Demonstration (ATD) project Rapid Transition from R&D to New Construction Example of what can be Accomplished when the Navy and Private Industry Work Together

16 Integrated Topside Goal
