Carbon Fiber 2012: Composites in aircraft wings

Carbon Fiber 2012, scheduled for Dec. 4-6 at the Hilton La Jolla Torrey Pines in La Jolla, Calif., will feature a presentation by University of Michigan professor Joaquim Martins on the design of composite and metallic aircraft wings.

CompositesWorld's Carbon Fiber 2012 conference, Dec. 4-6 at the Hilton La Jolla Torrey Pines in La Jolla, Calif., will feature a variety of presentations focusing on the supply, application and markets for carbon fiber composite materials.

One such presentation will be given by Joaquim Martins, associate professor and graduate program chair at the University of Michigan Department of Aerospace engineering. He will examine the design of metallic and composite aircraft wings to assess how the use of composites modifies the trade-off between structural weight and drag. He will use a gradient-based aerostructural design optimization framework that combines a high-fidelity, finite-element structural model that includes panel-level design variables with a medium-fidelity aerodynamic panel method with profile and compressibility drag corrections. He will show that the composite wing designs are lighter than the equivalent metallic wings. Due to this structural weight savings, the composite aircraft designs exhibit both fuel burn take-off and gross-weight savings. 

CompositesWorld’s Carbon Fiber 2012 conference, sponsored by C. A. Litzler and Harper International, will provide an objective, comprehensive forum to discuss new developments for carbon fibers in emerging industrial markets, such as wind energy, marine, and construction, as well as in traditional markets, such as aerospace and sporting goods. Discussions will focus on methods to streamline manufacturing costs in both industrial and aerospace applications and the outlook for consumption in markets with significant potential for growth.

Early bird registration for this important composites industry conference ends Nov. 2., and discounted hotel rates are available through Nov. 12. For more information or to register, visit
