New Approaches for Design, Optimization, Architecture and Manufacturing of Fiber Composite Structures
Themes: Leichtbau, Research and development in joining technologies
Developers and manufacturers of continuous fiber reinforced plastic components are facing several challenges within the competition to achieve minimum material usage and production cost in comparison to many other lightweight materials. This starts with the search for a suitable composite design of the components in the early design phase to obtain optimum stacking for maximum strength and stiffness. Other challenges are high requirements on tight tolerances and low warpage, high manufacturing cost for cutting the semi-finished products and their layup causing large amount of scrap.
Innovative methods which solve such diverse challenges of traditional composite designs using continuous fiber reinforcements will be presented here by giving suggestions for new structural design and configuration principles, analysis methods combined with an innovative manufacturing technique. Consequent use of those design principles, layout design and manufacturing methods will provide high performance composite components with improved strength and stiffness as well as less weight and material usage, less warpage and less scrap by applying efficient because simplified layup. The ideas are suited for different manufacturing processes like RTM or prepreg based technologies.
The methods to be presented have been developed by a team led by Prof. em. Stephen W. Tsai from Stanford University with patents pending and are promoted by an international team of researchers and companies which industrialize it and recommend its use. This consortium of institutes and associated companies supports the industry for implementation and use of those methods.
