Airbus integrates natural fiber composites and bio-based polymers - like flax, hemp, and recycled carbon fiber - into non-structural components of its aircraft. These materials not only reduce weight but also lessen the environmental impact.
For cabin interiors, Airbus uses bio-sourced thermoplastics derived from renewable resources such as corn starch and sugarcane. These materials deliver the same performance as traditional options while significantly lowering the carbon footprint.
Application Domain
The primary focus for these biodegradable materials is aircraft cabin interiors. Airbus has successfully applied them to various components, including seat parts, overhead bin panels, and decorative finishes. They’ve also been integrated into galley equipment, passenger service units, and other non-load-bearing structures within the cabin.
The A350 aircraft family serves as a testing ground for these sustainable materials. In select configurations, interior panels, armrests, and tray tables now feature bio-based materials that meet stringent fire resistance and durability standards. Beyond cabin interiors, Airbus has adopted biodegradable packaging for aircraft parts during production and delivery, paving the way for broader use of these materials across its operations.
Validation Stage
Airbus has moved beyond the experimental phase, achieving commercial implementation for several biodegradable material applications. The company has conducted rigorous testing and secured regulatory certifications for bio-based components used in passenger cabins.
To ensure consistent quality, Airbus collaborates closely with material suppliers. This partnership guarantees that all biodegradable components meet the necessary standards before receiving final approval for commercial use.
Standards and Requirements
All materials used by Airbus comply with the strict safety and flammability standards set by the FAA and EASA. These include benchmarks for heat release, smoke generation, and toxic gas emissions. Airbus also enforces stringent quality controls to ensure every material meets the demanding requirements of the aviation industry.
In line with its sustainability goals, Airbus incorporates renewable content and plans for end-of-life disposal into its design processes. This commitment ties directly to the broader theme of advancing sustainable innovation in aviation.
