Frewer Engineering’s composite structures team has completed the design of a complex carbon fibre structure using Cyanate ester resin system capable of withstanding temperatures up to 300 degrees C.
The structure includes a Flexcore aluminium honeycomb sandwich which facilitated the lay up over a complex double curvature surface shape.
The component, which is an aerospace application involved detailed vibration, thermal and shock loading to simulate in service environment loadings.
Frewer Engineering developed a new and novel sealing system too.
This new seal method involved co-bonding a Kevlar flexible material into the main structure allowing very large relative movements of adjacent components to be gas tight in service.
The components have just entered service with our customer and are being used to duct airflow around a pylon mounted civil aerospace engine.
