Composites

Clean technologies affect the choice of material for many applications; airplanes, cars, deep sea equipment or polar equipment. But the material is also becoming more and more interesting and important for e.g. kitchen appliances. Light weight materials, such as glass- and carbon fibre composites, are of great interest for product developing companies when looking for tremendous durability and high specific strength.

We believe that light weight materials will play a big role in finding the way to a sustainable society. We are determined to contribute in this aspiration! And we know that when we have successfully designed airplanes, wind power turbines or kitchen appliances that have effectively contributed to this aspiration, we will enjoy it for a moment, but then go after the next challenge. That is who we are and why we always strive to provide our customers with the latest know-how.

With more and more products incorporating composite materials as load carrying structure, it becomes ever more important to supervise the structural health through non-destructive inspection. We are currently developing techniques for active systems of structural health monitoring (SHM) utilizing acoustic emissions.

When initiating a structural analysis of a complex composite structure, we use commercial FE-codes such as ABAQUS CAE or MSC.Patran/Nastran. Our co-workers have been involved in the further development of composite modules for commercial FE-codes and we can support your company with similar tasks for development of specific modules fitted for your needs.

The curing of a carbon fibre epoxy composite give rise to residual stresses and/or shape distortions related to thermal or chemical effects. This generates substantial changes in the mechanical properties and geometric tolerances. We use FE codes to simulate and predict the shape distortions for the manufacturing of complex composite structures.
