The evolution of modern aviation cannot be understood without composite materials. Over recent decades, these materials have transformed the way aircraft are designed and manufactured, enabling lighter, more efficient and more sustainable structures.
At FIDAMC, we have been working for years on the development and industrialisation of advanced composite manufacturing technologies for the aeronautical sector. Our work enables us to participate in projects where composite materials are already a key element in the evolution of commercial aircraft and in the development of the aircraft of the future.
Today, manufacturers such as Airbus incorporate composite materials into a very significant proportion of their aircraft, particularly in next-generation programmes such as the A350 XWB, where more than 50 per cent of the structure is made from advanced composites.
Why are composite materials so important in aviation?
The main reason is simple: to reduce weight.
In aviation, every kilogram counts. A reduction in weight means:
- Lower fuel consumption.
- Reduced emissions.
- Greater range.
- Increased payload.
- Lower operating costs.
Composite materials offer strength levels comparable to — and even superior to — many traditional metals, but with significantly lower weight.
Furthermore, they offer other key advantages:
Greater resistance to corrosion
Unlike many metallic materials, composites exhibit excellent resistance to corrosion and fatigue, which helps to extend the service life of certain components.
Greater design freedom
Composites enable the manufacture of complex geometries and integrated parts with fewer mechanical joints.
This facilitates more aerodynamic designs and more efficient structures.
Structural optimisation
The fibres can be oriented according to the loads that each area of the part will bear.
This allows the structural behaviour to be optimised much more precisely than with traditional isotropic materials.
Where are composite materials used in Airbus aircraft?
Airbus currently uses composite materials in numerous structural and functional areas of its aircraft.
In the case of the Airbus A350 XWB, composites play a key role in:
- Fuselage.
- Wings.
- Tail sections.
- Fairings.
- doors.
- Interior elements.
- Secondary structural components.
The use of composites in the wings is particularly significant.
Thanks to these materials, it is possible to manufacture large structures that are highly strong yet lighter in weight, thereby improving aerodynamic efficiency and in-flight performance.
Programmes such as the Airbus A220 and the A320neo also feature significant applications of composite materials, although to a lesser extent than the A350.
The trend is clear: each new generation of aircraft progressively increases the use of advanced composites.
The challenge isn’t just the material: it’s also the manufacturing process
One of the major challenges facing the aerospace industry is not merely to design new materials, but to manufacture them on an industrial scale, in a repeatable and efficient manner.
At FIDAMC, we are working precisely on this transition between innovation and production.
The manufacture of composite components involves highly specialised processes, including:
- Automated fibre deposition.
- Automated lamination.
- Autoclave curing.
- Out-of-autoclave processes.
- Advanced robotics.
- Digital process monitoring.
- Non-destructive testing.
Each of these technologies requires very high levels of precision and control.
Minor variations in temperature, pressure or fibre positioning can directly affect the final performance of the part.
For this reason, a key part of our work focuses on:
- Automatización de procesos.
- Real-time quality control.
- Reducing cycle times.
- Industrial digitalisation.
- Validation of pre-industrial technologies.
A practical example: manufacturing automation in aerospace structures
A prime example of our work is the development of automated processes for the manufacture of complex carbon-fibre aerospace structures.
In many cases, the initial phases begin in the laboratory with small test specimens and material validation. Subsequently, development progresses towards larger-scale demonstrators and processes that more closely resemble actual production.
Significant challenges arise during this process:
- Ensuring repeatability.
- Avoiding internal defects.
- Coordinating robotic systems.
- Optimising manufacturing times.
- Reducing material waste.
- Integrating digital process data.
The ultimate aim is not merely to manufacture a lighter part, but to develop industrial processes capable of producing aerospace components to the levels of quality and traceability demanded by the sector.
In what direction are composite materials evolving?
The future of aviation will be closely linked to the development of advanced composites.
Key trends in the sector include:
Greater automation
Automation will continue to grow in order to increase productivity, improve quality and reduce manufacturing costs.
More sustainable manufacturing
The industry is increasingly focusing on:
- Recyclable materials.
- More sustainable resins.
- Reduced energy consumption.
- Out-of-autoclave processes.
Digitalisation and artificial intelligence
The integration of sensors, data analytics and artificial intelligence will enable real-time monitoring of manufacturing processes and the anticipation of defects before they occur.
New aeronautical architectures
The development of more efficient aircraft, advanced air mobility systems and even future hydrogen-powered concepts will require even lighter and more optimised structures.
Composite materials will play a vital role in this transformation.
Our role in developing the aircraft of the future
At FIDAMC, we are working to accelerate the industrialisation of advanced manufacturing technologies that will enable the aerospace industry to meet the challenges of the coming decades.
Our aim is to help transform innovation into industrial capability, collaborating with manufacturers, suppliers and research centres to develop more automated, efficient and sustainable solutions.
Because the aircraft of the future will not depend solely on new designs or new propulsion systems.
It will also depend on the ability to manufacture lighter, smarter and more competitive structures.
And along that path, composite materials will continue to play a leading role.
