Carville first produced acrylic components in the form of aircraft windows and canopies back in the 1940’s. These windows and canopies were used in both civil and military aircraft.
As aircraft evolved, there was a desire to remove weight and improve aircraft performance and fuel efficiency. Aircraft manufacturers began to adopt plastic materials such as Perspex acrylic for use in flight instrumentation.
Early flight instruments were laminated using adhesives, however, these manufacturing methods were not always reliable. An aircraft experiences extreme temperature variations when leaving the ground on a hot day (+40⁰C) and flying to high altitude (-50⁰C). Variable temperatures and material expansion and contraction can result in material delamination and component failure.
Carville developed our proprietary diffusion bonding techniques in the 1960’s which allowed acrylic material to be thermally bonded without the requirement for solvents or adhesive. The diffusion bonding process resulted in components which were mechanically strong and considerably more reliable.
Aircraft Lighting Components
In modern civil aircraft, each passenger’s seat has an overhead reading light. The light uses a single point light source and a lens to focus the light to a specific area within the passengers seating area. This allows individuals to have light without impacting on the comfort of other passengers. Carville manufacture a range of bespoke acrylic lighting components for aircraft customers in Europe and the USA.
Civil and military aircraft use lenses as part of the navigation and control systems. Carville manufacture light weight acrylic lenses with concave, convex or aspheric profiles.
Map and Storage Pockets
Aircraft flight decks require storage areas for plans, maps and other documentation that may be required during flight. Carville produce a range of bespoke storage pockets and compartments for use in civil and emergency service air support aircraft.
