Composite Structures Design and Analysis

Frewer Engineering supports a wide range of customers in the composites industry including aerospace, marine, wind generation and space. We have extensive experience in the design of carbon, glass & aramid composite structures and have well proven links with a variety of composite component manufacturers.

Client case

In common with all our composites projects, the development of an (E glass / Al Alloy Honeycomb) aero engine intake demanded weight saving and a high confidence of structural integrity. In addition to weight criticality, high loading created significant challenges, including overcoming a bad vibration environment. This was overcome by employing advanced forced vibration analysis design tools coupled with our knowledge of material strength allowables (we also designed the material itself).

We provide a complete composite structures design & structural analysis service. Our current capabilities include:

  • Composite structures design & analysis consultancy
  • Composite materials selection specific for each application / concept lay-up definition
  • Beyond first ply failure analysis
  • Finite element analysis (linear & nonlinear) of structures (with large scale model size capability)
  • Drape analysis of materials
  • Damage analysis
  • Iterative weight saving modelling of components
  • 3D CAD modelling & surface modelling of components
  • Design of tooling with links to manufacturers
  • Coupon testing definition and qualification planning
  • Production of information for manufacture (ply placement etc.)
  • Design of foam and honeycomb core structures
  • Design using resin infusion moulding
  • Shock & impact damage modelling of composites
  • Lay-up data for manufacture (both digital & 3D CAD drawings)

With long term relationships with a key composite research establishment, we are able to access a wealth of materials data enabling us to design with confidence.
