Why Are Composites and Additive Manufacturing Reshaping the Future of Flight?
The way aircraft are designed and built is changing faster than at any point in a generation. Writing in The Engineer, Jacqueline Castle, Chief Technology Officer at the Aerospace Technology Institute (ATI), sets out a compelling case. Advances in composite materials and additive manufacturing will underpin the future of UK aerospace — and the engineering supply chain needs to keep pace.
For precision mechanical engineering businesses, this is not a distant technology story. It is a live and growing demand signal.
Composites Are Now Central to Aerospace
Composite materials have long delivered exceptional strength-to-weight ratio, corrosion resistance and structural flexibility. However, their role in aerospace has moved well beyond specialist applications. Composites now account for over 50% of the weight of the Airbus A350 and Boeing 787, compared to just 6% of the Boeing 747. Furthermore, the next generation of single-aisle aircraft from Airbus and Boeing will likely feature predominantly carbon composite wings.
The global composites market will more than double in value from $16 billion in 2022 to $34 billion by 2032, with further growth expected out to 2050. The ATI estimates that the UK could grow its market share in aerospace composites by more than six times between now and 2050. Therefore, the opportunity for UK engineering businesses is substantial — but only for those who build the right capabilities now.
The UK Has a Strong Foundation
UK government and industry have invested £827 million through the ATI Programme towards composite material research and technology over the past decade. This investment gives the UK a genuine competitive position. A strong example is ICOMAT, which has commercialised the Rapid Tow Shearing process — the world’s first automated composites manufacturing technology that places wide composite tapes along curved paths without defects.
In addition, the National Composites Centre is anchoring future UK aerospace composite manufacturing through high-rate, sustainable processes — working in close partnership with the ATI. Consequently, the UK supply chain has access to world-class research infrastructure. This is a significant advantage for businesses seeking to develop composites capability.
Additive Manufacturing Changes the Production Equation
Alongside composites, additive manufacturing is transforming how aerospace components are produced. The ATI has published an additive manufacturing strategy and roadmap setting out the actions needed by 2028 for UK aerospace to capitalise on an AM market expected to reach £10 billion by 2033.
Additive manufacturing offers engineers a fundamentally different production paradigm. It consolidates complex assemblies into single parts, reduces tooling requirements and dramatically shortens time to first article. UK strategy is moving from material novelty toward production systems, tooling readiness and industrial evidence — with design increasingly governed by manufacturing evidence rather than theoretical potential. In other words, the industry now demands proven, repeatable processes — not just promising technology.
Precision Engineering Sits at the Heart of This Transition
New materials and new production processes both create new engineering challenges. Composite structures require bespoke assembly tooling, precision jigs and fixtures, and specialist test equipment designed around their specific mechanical behaviour. Additive manufactured parts demand new approaches to inspection, qualification and integration into wider structural assemblies.
Therefore, the shift toward composites and additive manufacturing does not reduce the need for precision mechanical engineering. It changes and deepens it. The engineering infrastructure required to design, assemble, test and validate next-generation aerospace structures demands exactly the kind of bespoke, analysis-led design capability that specialist consultancies deliver.
What This Means for the Supply Chain
The ATI’s vision is clear — the UK has the foundation, the investment and the technology to lead in aerospace composites and advanced manufacturing. However, realising that potential requires a supply chain capable of delivering precision engineering solutions that match the demands of next-generation programmes.
CNR has over 35 years of precision mechanical design and analysis experience spanning composite assembly tooling, bespoke special purpose machinery and custom test rig development for aerospace programmes. As the sector transitions to new materials and production methods, that depth of engineering experience becomes increasingly valuable.
