Composites Engineering

CompDesE joints profound knowledge in the materials and processes together with broaden network of university and industrial partners. This lead to a stedily supply of most innovative solutions.

The purpose of the engineering services is to verify simulation results through testing of part functionality and mechanical tests on prototypes. With our consulting services we help to keep component costs on affordable level to secure competitive advantages of your company.

The list below shows variables we consider be engineering your structural components:

  • Specific reinforcing fibers materials (carbon, glass, basalt, aramids, HMWPE's, white and black ceramics like Alumina and SiC)
  • Almost every available textile reinforcement: Braiding, Weaves, Warp-Knitted Spacer Fabrics, Non-crimp Fabrics, Multi-Filament Winding, Multiple Filament Winding, Automated Fiber Placements, Automated Tape Laying Stitching
  • Thermosets, Thermoplasts and ceramic matrix materials
  • Mechanical Testing

VARIM - Vacuum Assisted Resin Infusion Molding

CompDesE facilitate impregnation of composite reinforcements using Vacuum Assisted Resin Infusion Molding (VARIM) unit.

Description: VARIM is a composite production process in a closed mold (bottom) and vacuum bag (top) and belongs beside Resin transfer molding (RTM) to out of the autoclave (OOA) processes.

Mold: two portion of mold tool comprising a solid mold (bottom) and of a vacuum bag (top).

Infusion: a vacuum is used to facilitate resin flow and wet out of the textile reinforcement

Pressure: max. vacuum of 2 mbar (9996 kg/m2) secures high fiber volume fraction (50-60%) in manufactured composite

Curing: room temperature after infusion process, optional post-curing in oven depending on the matrix system.

Production capabilities: small-medium-very large-sized parts that can also be complex

Quality and mechanical properties: aerospace-grade with focus in in the marine, transportation and infrastructure markets.
