Our composite solutions help our customers enhance performance of their products while reducing weight, which decreases fuel consumption and associated carbon emissions. We have lightweight solutions that reduce noise pollution and solutions that help to produce clean and renewable energy.

The lightweight, adaptable nature of our materials makes products lighter, stronger and more durable. Therefore, our overall impact on the global environment is closely linked with our customers and their efforts to make products with a reduced impact on the environment. Whether the goal is to reduce fuel consumption, minimize total lifecycle operating and maintenance costs or lessen engine noise . . . or to support the production of longer and lighter wind turbine blades . . . Hexcel composites are a vital component in the process.

Each new generation of commercial aircraft has used increasing quantities of advanced composites to replace metals and reduce weight for more fuel-efficient aircraft with lower CO2 emissions. Every kilogram of fuel saved by an aircraft reduces CO2 emissions by more than three kilograms1.

Moreover, composite-based parts are corrosion resistant and stronger, leading to longer-life and increased safety and performance.


  • The composite-rich A350 provides a 25% advantage in fuel burn, operating costs and CO2 emissions compared to previous generation aircraft2.
  • Composite wing-tip extensions, such as those made by Hexcel, enhance fuel efficiency by improving airflow around the wing. For example, the Airbus A320 enjoys a 3.5% fuel efficiency improvement, reducing CO2 emissions by 900 tons annually per aircraft.3
  • Composite aircraft require fewer maintenance checks than metal aircraft as composites don’t corrode or suffer metal fatigue. The composite-intensive A350 requires 50% fewer structure maintenance tasks, and the threshold for airframe checks is 12 years, compared to eight for the A380, which has a metal fuselage and metal wings.4 
  • The LEAP engine uses lightweight and durable carbon fiber fan blades, leading to a 500-pound weight reduction per engine and a 15% improvement in fuel economy compared to predecessor metal fan blades.5
  • Our HexWeb® Acousti-Cap® sound attenuating honeycomb provides dramatic noise reduction during takeoff and landing without a structural weight penalty, such as a 40% noise reduction in the engine of the Boeing 737 MAX compared to its predecessor.6
  • We have supported wind turbine production worldwide for more than 20 years with leading-edge composite solutions offering longer, lighter, stiffer and more efficient blades.
