Topology Optimization of Fiber Composites

platon-small.jpg As part of the European Union-funded research project PLATO-N (Platform for Topology Optimisation incorporating Novel, Large-Scale, Free Material Optimisation and Mixed Integer Programming Methods [2006-2009]), mathematical methods and software tools for the computeraided design of aircraft structural parts made of composite materials were developed. 

Unlike isotropic materials, such as aluminum or steel, composites offer much more design freedom. Thus, with modern production technologies, fiber directions and layer thicknesses can be chosen almost arbitrarily, so that material properties can be individually tuned according to the structures of the components.

An important result of PLATO-N was the development of a prototypical software system that supports design engineers in the conceptual phase. With the help of specially developed optimization methods, minimized weight concept designs for the geometry of the structure (and thus for the structure topology) and the material properties are calculated. 

The project‘s international partners were universities and research institutes, aviation and aerospace companies, as well as CAE and software development companies from six nations. Project management was carried out by the Technical University of Denmark.
