Today, simulations are mostly used to validate construction designs, i.e. the geometry is already defined in a certain material, is checked and, if necessary, improved. This goes so far that manufacturers do not use technologies that they cannot simulate - a real obstacle to the establishment of composite materials.
Manufacturing determines properties
The properties of fiber composites depend on numerous variables such as fiber volume content, layer structure, semi-finished product type, fiber draping and the processing parameters and only arise during production. Although there are characteristic values of the starting materials, which are often used like the material data of classic materials, the manufacturer is deprived of the greatest advantage of fiber-reinforced plastics: instead of optimizing the geometry of the prototype at great expense in time and money, one could adapted development processes, the material properties can easily be adapted. "If you follow the conventional, design-based development approach, composites give you a component that is lighter than steel, but not as light as it could be," summarizes Dr. Thomas Burkart,Group leader technical calculation & simulation at ARRK | P + Z Engineering, the problem together.

Material model developed for the strength analysis of fabric-reinforced fiber composite materials
As an alternative, the company's experts have designed an approach that is tailored to the peculiarities of composite materials and based on technical calculations. The starting points are the given installation space as well as the development goals and application requirements.

Determine load paths
On this basis, a topology analysis is first carried out to determine the main load paths. "This enables us to assess very early on in the concept phase at which points single or multi-axial loads occur and to coordinate the further planning accordingly," explains Monika Kreutzmann, head of the Center of Competence (CoC) for composites at ARRK | P + Z engineering. "With standard methods, it is very late to determine where which loads occur, which entails additional, expensive development loops."
