What CompPair does
CompPair Technologies Ltd. is a Swiss deep-tech materials company headquartered at EPFL Innovation Park in Lausanne/Renens, spun out of EPFL's Laboratory for Processing of Advanced Composites (LPAC) in 2019–2020. The company develops HealTech™, a proprietary thermoset-based resin system that gives fiber-reinforced polymer composites the ability to self-heal cracks, delaminations, and microcracks in approximately 60 seconds through localized heating at 100–150°C, with 60+ healing cycles per part and full retention of mechanical properties. The technology is supported by over a decade of EPFL research and is protected by registered trademarks and filed patents.
The HealTech platform is a multi-product offering covering different composite manufacturing processes: the CS01 high-toughness prepreg, the CS02 Swift prepreg (50-minute press cycle), CS03 slit tapes for automated layup, LCS01 and LCS02 liquid composite molding systems for infusion and RTM, a 2025-launch Healable RTM system, and semi-finished products including tubes, thermoformable sheets, sandwich panels, and monolithic plates in carbon, glass, recycled carbon, and natural fibre reinforcements. CompPair also sells professional services — implementation support, life-cycle analysis (LCA), eco-design, and repairability quantification — to help customers integrate the materials into qualified parts.
CompPair operates a B2B enterprise model targeting tier-one composite manufacturers and integrators across aerospace, rail, mobility, luxury goods, sport, and industrial sectors. Revenue is generated through one-time sales of prepregs and resin systems plus recurring service revenue, with quote-based pricing tied to reinforcement type and volume and multi-year contracts. Distribution is direct and via strategic material-provider partnerships (SHD Composites, Diab, KS Composites, Axalp Technologies), supported by marketing at JEC World, Paris Air Show, Space Tech Expo, and content channels. Named customers and partners include SBB Swiss Federal Railways, ID Genève, Gunboat, KS Composites, Axalp Technologies, 3A Mobility, TWIICE, plus ESA-backed projects with CSEM, Com&Sens, Invent, and Orbex.

CompPair competitors and assessment
Company assessmentDirect peers
- Bcomp: Swiss-based composites company specializing in natural fibre reinforcements for high-performance applications in mobility, sports, and aerospace. Highly comparable to CompPair as a fellow EPFL-connected Swiss composites startup with sustainability positioning and overlapping customer base; notably, CompPair's CTO Robin Trigueira previously worked at Bcomp on natural fibre reinforcements.
- SHD Composites: UK-based manufacturer of high-performance prepreg materials for composites. Direct peer to CompPair as both operate in the same prepreg product category; the two companies also maintain a strategic partnership to integrate HealTech resin systems into SHD's broader prepreg offering.
- Autonomic Materials Inc. US-based specialty materials company developing self-healing polymer and coating technologies for industrial applications. Most directly comparable to CompPair's HealTech platform as both companies commercialize self-healing material chemistries, although Autonomic focuses primarily on coatings rather than structural fibre-reinforced composites.
Broad incumbents
- Gurit: Swiss-listed composite materials manufacturer with established portfolio of prepregs, core materials, and engineered composites serving wind energy, marine, and aerospace markets. Comparable to CompPair as a Swiss composites incumbent with overlapping customer base, though operating at significantly larger scale with broader product lines.
- Hexcel: US-based global leader in advanced composites technology, particularly carbon fibre reinforcements and prepregs for aerospace and industrial markets. Comparable to CompPair through overlap in aerospace end-markets (the same customer base as ESA and Axalp partnerships), though Hexcel serves these customers with a much broader portfolio.
- Toray Industries: Japanese multinational with the world's largest carbon fibre production capacity and a significant composites materials portfolio spanning aerospace, automotive, and industrial markets. Comparable to CompPair through overlap in carbon-fibre-reinforced composite materials, though Toray operates at vastly larger scale and a more diversified product mix.
- Solvay: Belgian specialty chemicals and advanced materials company with a significant composites and polymer business serving aerospace, automotive, and industrial markets. Comparable to CompPair through overlap in advanced resin systems and aerospace customers (overlapping with CompPair's ESA and SBB partnerships), though Solvay operates a much broader portfolio of materials.
- SGL Carbon: German manufacturer of carbon-based products including carbon fibres, composite materials, and specialty graphites serving automotive, aerospace, wind, and industrial applications. Comparable to CompPair through overlap in carbon-fibre-reinforced composites for industrial and aerospace applications, though SGL focuses on raw fibre and intermediate materials rather than finished self-healing systems.
- Trelleborg: Swedish engineered polymer company producing sealing solutions, anti-vibration components, and engineered composites for aerospace, automotive, and industrial customers. Comparable to CompPair through overlap in advanced polymer materials and aerospace/industrial applications, though Trelleborg's portfolio is significantly broader and focused on sealing/damping rather than self-healing structures.
Others
- Diab: Swedish manufacturer of high-performance foam core materials for composite sandwich structures serving aerospace, wind, marine, and industrial markets. Closely related to CompPair through their announced cooperation agreement to combine Diab's Divinycell cores with HealTech for sandwich structures; Diab serves as a complementary materials supplier rather than direct competitor.
