Dassault Inmotion Using Composites in Alternative Energy Industries
Presented by Jeff Sloan, Editor-in-Chief, High-Performance Composites, Composites Technology & CompositesWorld Weekly
The Future is Now
- Wind blades are turbine-mounted air foils—basically highly engineered wings
- Design and manufacture of wind blades should emulate design and manufacture of wings and rotors for aerospace applications
- Best practices in aerospace design and manufacture require use of dynamic and flexible CAD/CAM, simulation and manufacturing systems
This webcast is will help composites professionals understand best practices and options for optimizing wind blade design and manufacturing
Applications
- Wind blades, wind turbine nacelles
- Bi-polar plates for fuel cells
- Hydrogen and compressed natural gas storage
- Marine turbine systems
- Flywheels for wind energy storage
Wind Blades
- Fastest-growing segment of composites manufacturing industry
- Anticipate demand for 140,000 wind blades annually by 2017 — that’s 383 blades/day
- Current manufacturing technology grew out of boat-building industry and relies on hand layup of composite materials
- Result is inconsistent quality, high void content in composite structures, high scrap rates, product failure
Wind blade manufacturers demand consistent quality at high speeds

Materials & Processes: Fibers for composites
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.

Materials & Processes: Resin matrices for composites
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
