SOCIETE NATIONALE DE CONSTRUCTION AEROSPATIALE SONACA SA

Their core work

SONACA is a Belgian aerospace structures manufacturer specializing in the design and production of aircraft wing components, nacelles, and fuselage panels. They bring deep expertise in advanced composite materials, metallic aerostructures (particularly aluminium alloys), and ice protection systems for aviation. Their R&D work focuses on making aircraft structures lighter, more damage-tolerant, and more manufacturable — spanning from materials science through simulation to full-scale demonstrator testing. As an SME with Tier 1 supplier characteristics, they bridge the gap between laboratory-scale material innovations and industrially viable aerospace manufacturing.

What they specialise in

How they've shifted over time

In 2014–2018, SONACA focused on fundamental materials performance — self-healing composites, nanoadditives, erosion resistance, and multi-scale modelling — essentially building the science base for next-generation aerostructures. From 2019 onward, their work shifted decisively toward industrialization and integration: graphene pilot lines, full-scale aircraft demonstrators (GAM-2020-LPA, their largest project at EUR 1.36M), virtual testing for certification (TIOC-Wing), and end-of-life recycling (ReINTEGRA). The trajectory shows a company moving from "what materials can do" to "how we manufacture, certify, and sustain aircraft structures at scale."

SONACA is moving toward digital certification (virtual testing replacing physical tests) and circular aerospace manufacturing, making them a strong partner for projects targeting sustainable aviation and next-generation aircraft programs.

How they like to work

SONACA operates primarily as an active partner (17 of 23 projects), but steps up to coordinate when the topic is squarely in their manufacturing sweet spot — they led 5 projects including ice protection (I3PS, BISANCE), metallic joining (IAWAS), composite wing testing (TIOC-Wing), and skin panel manufacturing (MISSP). With 392 unique partners across 28 countries, they are a well-connected hub in European aerospace R&D, comfortable working in both large Clean Sky 2 consortia and smaller focused research teams. They are a reliable industrial end-user partner who brings real manufacturing constraints and validation capabilities to research consortia.

SONACA has built an extensive network of 392 unique partners across 28 countries, heavily anchored in the European aerospace supply chain through Clean Sky 2 and Graphene Flagship programs. Their partnerships span from large OEMs and Tier 1 suppliers to universities and research institutes across Western and Central Europe.

What sets them apart

SONACA occupies a rare position as an aerospace SME that operates at Tier 1 supplier scale — they manufacture real aircraft components (wing skins, leading edges, nacelle parts) while remaining agile enough to engage deeply in R&D. This means they can take a material innovation from lab-scale composite testing all the way to flight-qualified hardware, which most SMEs and most large primes cannot do in one organization. Their combined expertise in composites, ice protection, and metallic aerostructures makes them a one-stop validation partner for anyone developing new materials or processes for aircraft structures.

Highlights from their portfolio

• GAM-2020-LPA
  Their largest project (EUR 1.36M) — a full-scale large passenger aircraft demonstrator integrating advanced propulsion, hybrid laminar flow, and multifunctional fuselage concepts.
• TIOC-Wing
  Coordinated project (EUR 912K) combining virtual testing with physical validation for composite wing damage — directly targeting certification methodology that could reduce costly physical tests.
• BISANCE
  Coordinated an unusual integration challenge — embedding biphasic heat transport into composite nacelle structures for anti-icing, combining thermal engineering with structural composites.
