Large Composite Structure

The Composite Materials Division at ARL has earned a leadership role in the development of composite technology for a broad range of both military and industrial applications. To support this role, ARL has assembled an experienced technical staff, established complete in-house design and analysis, fabrication and testing facilities, and has developed an extensive network of proven subcontractors.

Technology Thrusts:

• Active and passive noise and vibration control using composite materials
• Thick laminate (>8") fabrication techniques
• Strength-based and fracture mechanics-based fatigue test methodologies
• Life prediction models for complex geometry composite hardware
• Low-cost fabrication techniques for marine and industrial structures
• Advanced ultrasonic inspection and in-situ acoustic emission monitoring techniques

Concurrent Engineering:
ARL utilizes a concurrent engineering approach in developing composite structural applications. This concurrent engineering approach mandates a close and continuous interaction between all key technology disciplines including structures, acoustics, materials, manufacturing, and quality control to ensure that the delicate balance between structural integrity, performance, producibility, and cost is maintained. This approach has been successfully demonstrated by designing, fabricating, and testing full-scale composite structures on a variety of U.S. Navy and industrial programs.
