Innovations in aerospace: The role of composite materials in modern aircraft design

Introduction to composite materials in aerospace

Composite materials are not new, but advancements in their engineering have made them a perfect fit for the demanding requirements of modern aircraft. These materials combine two or more distinct components, typically fibres (like carbon fibre or fibreglass) embedded in a resin matrix (like epoxy). This unique structure offers a winning combination of properties that traditional materials like aluminium struggle to match.

Advantages of composite materials in aircraft design: Boosting performance and efficiency

Here’s why composite materials are soaring high in the aerospace industry:

  • Strength-to-weight ratio: Composites boast exceptional strength while remaining remarkably lightweight. This translates to lighter aircraft, improved fuel efficiency, and increased range.
  • Corrosion resistance: Unlike metals, composites are highly resistant to corrosion, which minimises maintenance needs and extends the lifespan of aircraft components.
  • Design flexibility: Composites offer greater design freedom compared to traditional materials. Their versatility allows for complex shapes and aerodynamic profiles, optimising flight performance.

Airbus A350 XWB: A case study in lightweight design with composites

Leading aircraft manufacturers are increasingly incorporating composite materials into their designs. A prime example is the Airbus A350 XWB, which extensively uses carbon fibre-reinforced plastic (CFRP) throughout its airframe, including the upper and lower wing covers, fuselage panels (excluding the nose), and vertical and horizontal stabilisers. This innovative approach has resulted in a significant weight reduction of 25% compared to its predecessor models, translating to a remarkable 20% improvement in fuel efficiency (Source: Airbus). 


High-performance composite materials like CFRP are crucial for achieving such weight reduction. Leading composite suppliers, like GMS Composites, offer a diverse range of prepregs and expertise to meet the demanding requirements of these applications.


The Airbus A350 XWB is just one example, showcasing the transformative power of composites. Many leading aircraft manufacturers are increasingly incorporating composite materials into their designs.
