Advanced composite manufacturing

Sandwich panels have been used in modern aircraft and transportation solutions for many years already. High rigidity and low weight, as well as a high degree of functional integration of components are essential properties. The manufacturing of sandwich panels with optimal properties necessitates continual process control. CNC-assisted machines ensure optimal production processes and high quality.

Our competences:

Fiber reinforced plastics:

  • Sandwich panels with different GFRP and CFRP-skins and different core materials (e.g. honeycomb, foam)
  • Laminate parts (flat and 3D)

VAP®-components: Impregnated monolithic and sandwich structural components

Our know-how:

  • Installation of plug in parts (e.g. laminates, metal parts) for load application before curing
  • Implementation of local reinforcements
  • CNC-filling of honeycombs

Our technologies:

  • CNC-cutting of preimpregnated fibres (prepregs)
  • Automated and manual tape laying
  • Machining of honeycombs
  • Core filling
  • Press-Curing and Furnace-Curing
  • 3- and 5-Axis CNC-Machining
  • VAP® (Vacuum Assisted Process) technology

New lightweight materials and combinations

Together with our customers and suppliers and as part of an expanded network of universities and research institutes we explore innovative materials, develop new material combinations and more efficient sandwich lay-ups. EFW´s in-house testing capabilities ensure an effective material research, product development and certification. Therefore we are able to conduct all necessary material and part related tests:

  • Tensile, compression and shear tests for sandwich parts, core materials (e.g. honeycomb) and laminates
  • Special part tests: full scale shear, bending under static load and food cart roller tests
