COMPOSE SAS

Their core work

COMPOSE SAS is a French SME based in Bellignat (Ain), near the historic "plastics valley" of Oyonnax, developing software tools and process engineering solutions for composite materials manufacturing. Their work centers on advanced thermoplastic composite fabrication techniques, including Quilted Stratum Processes (QSP), which enable cost-effective and environmentally lighter production of complex composite parts. Both of their EU research engagements are within Clean Sky 2 — the EU's flagship aeronautics program — indicating that aerospace is their primary application domain. The company's website name (compose-tools.com) reinforces their identity as a tool-developer rather than a materials supplier: they build the digital and process infrastructure that manufacturers use to work with composites.

What they specialise in

How they've shifted over time

No keyword metadata was extracted for either project, making precise evolution analysis impossible. What can be inferred from project dates and titles is that COMPOSE SAS entered H2020 through a broad Clean Sky 2 systems program (SYS GAM 2018, from 2014), then moved toward a more specific process-technology role in thermoplastic composites manufacturing (SHERLOC QSP, from 2017). The shift from systems-level to process-level work suggests a narrowing and deepening of their niche, moving closer to the manufacturing floor and away from higher-level aircraft integration challenges.

COMPOSE SAS appears to be specializing deeper into process and tooling for thermoplastic composites, a technology segment with strong growth as aviation OEMs push for lighter, recyclable structures — making them a plausible partner for future calls in sustainable aeronautics manufacturing.

How they like to work

COMPOSE SAS has participated exclusively as a consortium member, never as a coordinator, across both projects. Despite having only two projects, they have accumulated 69 unique partners across 12 countries — a figure explained by Clean Sky 2's characteristically large, multi-partner Innovation Actions. This indicates they are comfortable operating within complex consortia but have not yet taken on the administrative and scientific leadership role of coordinator. Working with them likely means engaging a focused technical contributor rather than a project management hub.

With 69 unique consortium partners across 12 countries from just two projects, COMPOSE SAS has unusually broad network exposure for its size — a direct consequence of the large Clean Sky 2 program structure. Their network is European in scope, likely concentrated in France, Germany, Italy, Spain, and the UK, which are the dominant aerospace nations in Clean Sky 2.

What sets them apart

COMPOSE SAS occupies a specific niche at the intersection of software tooling and advanced thermoplastic composite manufacturing — a combination that is rare among French SMEs. Their location in the Ain/Oyonnax plastics cluster gives them proximity to an industrial ecosystem of materials processors, which is a practical advantage for prototyping and partnership. For consortium builders seeking a specialist SME with proven Clean Sky 2 track record and deep composites process knowledge, they offer a credible and focused profile that generalist engineering firms cannot match.

Highlights from their portfolio

• SYS GAM 2018
  The largest single grant received (EUR 400,580) and the longest project duration (2014–2019), placing COMPOSE SAS within Clean Sky 2's Systems ITD — one of the program's most strategically significant technology demonstrator tracks.
• SHERLOC QSP
  The most technically revealing project in their portfolio: directly named after Quilted Stratum Process technology, it confirms composites manufacturing process development as a distinct and deliberate area of expertise.
