Typical types of aircraft components are exterior access doors that protect avionics equipment, stiffing ribs and spars in larger assemblies and wing skin panels. Many components go into larger assemblies with complex hardware, strict non-destructive inspection requirements and elaborate coatings for static dissipation and rain erosion.
These components are typically constructed with Carbon/Epoxy prepregs and tapes. Sandwich components are also typical with both metallic and non-metallic honeycomb core. Carbon/epoxy structural components require exacting dimensions and high strength. These properties are accomplished through autoclave curing and CNC machining.
Carbon/epoxy facings are cured then NDI (non-destructive inspection) tested. Then facings are bonded to honeycomb core with structural adhesive. The panels are trimmed and drilled with CNC mills. The honeycomb sandwich is NDI C-scan inspected; the hardware is then assembled. Sample laminates are also made and can be tested as representative of actual parts.
