Our Composite Manufacturing Process
Design & Engineering Support
We work with clients from the concept stage, providing design and engineering input rather than just building to a finished drawing, so components meet both the technical spec and the practical constraints of the cabin.
Material selection
Components are built using fibre-reinforced plastic (FRP) and honeycomb structures, chosen for the strength-to-weight performance required in aerospace and military cabin interiors.
Fabrication & moulding
Custom mouldings are produced to client specification, including fixings and attachment points built directly into partitions and class dividers, so components arrive ready to install rather than needing separate fitting work.
Testing
Components go through testing as part of the manufacturing process to confirm they meet the required standard before delivery.
Quality inspection & certification
Produced and inspected under 21 Aero’s CAA Part 21G approval, with full traceability documentation.
Delivery
Supported by our supply chain and industry partnerships, so components are delivered on time and ready for installation.

Frequently Asked Questions
Frequently Asked Questions
What is aerospace composite manufacturing?
Aerospace composite manufacturing is the design and production of lightweight, high-strength components — typically made from materials like carbon fibre or glass fibre composites — for use in aircraft interiors and structures. These components must meet strict aviation certification standards.
Is 21 Aero an approved composite aircraft manufacturer?
Yes. 21 Aero holds CAA Part 21G approval, which covers the production of aerospace parts to approved design data, from our Warrington facility.
Does 21 Aero manufacture custom composite components?
Yes — 21 Aero produces custom composite fabrication to client specification, rather than working from a fixed catalogue of parts.Â
