From trains to space: Healable composites take off in 2025!

From railways to orbit, 2025 gained speed. Here’s a snapshot of how we advanced repairable, sustainable composites across industries.

Repairable composites enter the SBB railways

CompPair is proud to partner with SBB to integrate repairable composite technology into the iconic ICN trains. Our HealTech™ materials are now part of the SBB supply chain, starting with the cowcatcher—one of the most frequently damaged components.

This collaboration aims to reduce maintenance time, extend part lifetime, lower operational costs, and support the rail sector’s transition towards more sustainable operations. It’s a strong demonstration of how repairable composites can deliver real impact at scale.

Sustainability on display: The SDG watch at Climate Week

In collaboration with ID Genève and the United Nations, CompPair contributed to the creation of the SDG Watch, unveiled during Climate Week. Only 17 watches were produced—each representing one of the UN Sustainable Development Goals. Reserved for sustainability leaders, the watch symbolises long-term commitment, durability, and responsible innovation.

Climate Week 2025: From inspiration to action

Climate Week 2025 reinforced a clear message: collaboration and action are essential. At the Swissnex Planetary Embassy, discussions challenged us to rethink humanity’s role within planetary boundaries. At The Nest Climate Campus, CompPair’s CEO Amaël joined a panel hosted by Action Speaks and The Biomimicry Institute, exploring how nature-inspired innovation can drive resilience and regeneration. At CompPair, biomimicry is more than a concept, it’s embedded in our healable composites, designed to regenerate, reduce waste, and make circularity tangible.

Enabling healable composite manufacturing with slit tapes for space applications

In 2025, CompPair made major strides in space-ready healable composites, successfully concluding an ESA Open Space Innovation project focused on HealTech™ slit tapes for cryogenic tanks. Over 18 months of development and testing, we demonstrated compatibility with demanding space requirements, including resistance to cryogenic microcracking, ultra-fast healing of damage, and validated outgassing performance. These results pave the way for lighter, liner-less Type V pressure vessels and mark an important step towards more durable, reusable composite structures for future space missions.

Repairability gains momentum in the RV industry

Hail damage remains the leading cause of motorhome repairs, driving high costs and long downtimes. HealTech™ offers an alternative: GRP sandwich panels that heal dents and microcracks in minutes using heat, reducing repair costs by up to 40×.

CompPair recently joined a Repair Committee meeting organised by the Caravaning Industrie Verband e.V., contributing to discussions with manufacturers, insurers, and repair experts on how repairable materials can transform the industry.

Events & Public Appearances

• At SAMPE Europe (Amsterdam), our CEO Amaël Cohades presented healable composite structures for tank applications, highlighting durability and sustainability benefits.

• At Space Tech Expo Europe, Bertrand Gresle and Cecilia Scazzoli engaged with the space community on regenerative composites for extreme environments.

• CompPair joined key discussions at the Aviation Forum, exploring solutions to reduce downtime and extend component lifetimes.

  In Brussels, our Sustainability Manager Eléonore Wild represented CompPair at the EuCIA General Assembly, contributing to the European Circular Composites Alliance and advancing circular business models across the industry.

As the year comes to a close, we’d like to sincerely thank our partners, customers, collaborators, and community for the trust, energy, and ambition you’ve shared with us throughout 2025. We’re heading into 2026 with momentum, conviction, and exciting developments ahead. Until then, we wish you a restful festive season and a bright, impactful start to the new year.
