What Magma Composites does
Magma Composites is a French B2B subcontractor that manufactures high-tech composite parts for the aeronautics, competition nautism, defense, and road/rail transport industries. The company is headquartered in Questembert, Brittany, and operates 860m2 of workshop space organized into three specialized bays: a 450m2 infusion and wet-vacuum workshop, a 250m2 pre-impregnated (prepreg) workshop in a controlled grey-zone atmosphere, and a 160m2 carpentry bay with 3-axis CNC milling. Supporting infrastructure includes a 12.5m x 5.5m x 2.3m temperature-controlled oven (with 0.5°C/minute ramp control and thermocouple monitoring), 18m3 of cold storage at -18°C for prepreg conditioning, and a 3-axis machining center for finished-part machining.
The company offers three core composite transformation processes — wet layup under vacuum, resin infusion, and prepreg fabrication — applied across prototype tooling, small-series high-temperature tooling, demonstrators, prototypes, and series production. An integrated design office (bureau d'études) handles project management, composite design, methods definition, production, full traceability, and QHSE management, allowing Magma to take client specifications from conception through delivery. Customer relationships are project-based and quote-driven, with capabilities positioned around weight reduction, complex geometries, function integration, and surface finish compliance for demanding end markets.
The go-to-market model is sales-led direct B2B engagement, supported by a multilingual website and organic social presence on LinkedIn, Facebook, and Instagram. Magma supplements its internal capabilities with a network of material suppliers (Gurit, Sicomin, Euro-Composites, Composites Distribution, Guelt, Gazechim, AMC44) and technology partners (Modul-tech for tooling, CML-TPF for metrology, Bony3D for additive manufacturing). The company is privately held, employs 11-50 people, and does not disclose revenue, funding, or ownership structure.

Magma Composites product offering
Product offeringCore offering
Magma Composites is a B2B composite parts fabrication workshop with an integrated engineering bureau, manufacturing high-tech composite parts using three processes: wet layup under vacuum, resin infusion, and pre-impregnated composite fabrication. The company delivers prototypes, demonstrators, tooling (ambient to high-temperature), and small-to-medium series production for aerospace, competitive sailing, defense, and road/rail transport clients. Customers supply technical specifications and Magma executes the full project lifecycle including design, methods, production, traceability, and QHSE management.
Product overview
Magma Composites is a composite fabrication workshop with an integrated engineering department, offering three core manufacturing processes: wet layup under vacuum, resin infusion, and prepreg composite fabrication. These processes are applied across four service lines — prototype tooling and small-series high-temperature tooling, composite prototypes and demonstrators, and series production — serving aerospace, competitive sailing, defense, and rail/road transport industries. The integrated engineering bureau provides full-cycle capabilities from project management and design through production, traceability, and QHSE.

Magma Composites competitors and assessment
Company assessmentDirect peers
- Loiretech: Loiretech is a French specialist in composite tooling and prototypes for aerospace, defense, and energy. Directly comparable to Magma's high-temperature tooling and small-series scope, with similar customer types and project-based revenue model.
- Coriolis Composites: Coriolis (Morlaix, Brittany) supplies automated fiber placement machines and produces composite parts for aerospace and industrial customers. Comparable in process focus and Breton roots, though Coriolis has a stronger equipment/automation IP angle than Magma's pure fabrication model.
- Multiplast: Multiplast (Vannes, Brittany) is a French composite parts manufacturer serving competitive sailing, aerospace, and industry — directly comparable to Magma in process set (prepreg, infusion), geography, customer mix, and scale. The two are the closest direct peers in the Brittany composite subcontractor cluster.
- Carboman Group (formerly Decision SA / Carboman): Carboman designs and manufactures large composite parts for aerospace, marine, and transport using prepreg, infusion, and RTM processes. Comparable to Magma in process technology, end-market mix, and project-based B2B model, though somewhat larger and with broader geographic reach.
- Aero Composite Industries (ACI): Aero Composite Industries is a French composites manufacturer focused on aeronautics tooling, prototypes, and small series. Comparable to Magma in process capabilities (infusion, prepreg), aerospace vertical focus, and small-to-mid scale.
Broad incumbents
- Daher: Daher is a large French industrial group with a significant aerospace composites business serving Airbus, Safran, and other primes. Overlaps with Magma in process technology and customer verticals but at a much larger scale and with full aerospace certifications, acting as a broad incumbent in the same end markets.
- Stelia Aerospace (Airbus Atlantic): Stelia / Airbus Atlantic is a major European aerostructures manufacturer producing large composite fuselage and structural parts. While much larger than Magma, it defines the supply ecosystem (subcontractor pool, certification requirements) in which Magma competes.
- Latécoère: Latécoère is a tier-1 French aerospace supplier with a substantial composites aerostructures business serving Airbus. Operates broadly in the same end markets as Magma but at vastly greater scale, with full prime-contractor accreditations.
- Groupe Benéteau (Marine): Benéteau is one of the world's largest sailing-yacht builders and consumes composite parts at scale from its own facilities and from French composite subcontractors including those comparable to Magma. Relevant as both a potential customer and a benchmark for the marine composites value chain.
Others
- Hexcel Corporation: Hexcel is a leading global manufacturer of advanced composite materials (carbon fiber, prepregs, honeycomb) — a key upstream supplier to the same aerospace, defense, and industrial customers Magma serves. Relevant as an adjacent/ecosystem player that defines the material supply chain Magma depends on.
