Calculation & Layout

Our competence in the field of calculation and layout comprises the complete chain of production of fibre composite components - starting with tool design and dimensioning to strength testing and optimization of the complete component. We draw up processing analysis for you by means of the finite elements method for fibre composite plastic, hybrid (combination of light metal and fibre composite plastic) or metal based construction.

Services

Our range of services in the field of calculation and layout extends over:

  • Calculation and design of fibre composite plastics according to VDI 2014

Simulation of a winding process of a carbon fibre-reinforced plastic test specimen  

Process simulation:

Task:

  • Preparatory consideration of the production of a carbon fibre-reinforced plastic hollow shafts test specimen with thickened  end areas

 

Solution:

  • Simulation of a winding process with Software CADWIND

 

Advantages for customers:

  • Better component qualitiy because of theoretical predictions of an optimal winding parameter
  • Exact estimation of process sizes, e. g. winding duration, fibre and resin needs
  • Knowledge of the exact fibre orientation as a foundation of FEM strength calculations

Strength and rigidity proof of a carbon fibre-reinforced plastic  

Component simulation

Task:

  • A dynamically loadable machine lever of aluminium shall be replaced by a carbon fibre-reinforced lightweight construction. With maximum weight saving the rigidity and maximum permissible deformation have to correspond to the demands.

 

Solution:

  • FEM-based simulation of different construction variations
  • Optimization of component geometry and carbon fibre-reinforced plastic layer structure
  • Strength and maximum deformation proof by calculation

 

Advantages for customers:

  • Optimally designed, weight-reduced components that are suitable for their use
