Frewer Engineering provides composite structures design and analysis services to 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.
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.
