Sigma specialises in the design and manufacture of advanced composite components, supporting aerospace and defence OEMs and Tier 1 customers in pursuit of their weight. PFW Aerospace has been supplying metal tubing to the aerospace industry for nearly years.

Given the increasing demands to reduce weight, we needed to identify alternatives to metal. We worked closely with Victrex for more than three years, involving them in every stage of the product development phase through to the qualification.

After air drying for one hour, the coated parts should be baked until the resin coating exhibits a distinct green coloration. Test procedures call for the metal panels to be baked at Degrees F +/- 5 Degrees, however, the size and shape of the parts may require deviation from this schedule inorder to obtain full cure and Size: KB.
