Film and paste adhesives, wet peel-ply and potting compounds enable the aviation industry to utilize advanced materials that contribute to lightweighting, more efficient designs, and improved sustainability.
From the earliest days of aviation, aircraft structures were made of metal. Gradually, aluminum emerged as the preferred option for primary, secondary and tertiary structures because of its lightweight, alloying capabilities, fatigue performance, and lower cost of production compared to other materials.
The latest generation of aircraft incorporates advanced composite materials that can be optimized to specific aircraft design requirements. By weight, both the Airbus A350 and the Boeing 787 are comprised of about 50% composites.
This evolution has been hastened by the many benefits composites provide, such as:
- High strength
- Corrosion resistance
- High strength-to-weight ratio
- High impact strength
- Thermal and electrical insulation
One of the most significant advantages to composites is in lightweighting. The reduction of an aircraft’s weight provides a range of benefits. A lighter aircraft uses less fuel, contributing to sustainability and lower emissions.
