CompPair, a pioneer in healable composite technologies, is proud to announce a cooperation agreement with Diab, a global leader in high-performance core materials. The partnership focuses on healable sandwich structures, combining Diab\u2019s Divinycell core materials with CompPair\u2019s HealTech\u2122 ultra-fast composite repair technology. These solutions make it possible to recover from impact and target both exterior and interior aerospace applications, and a wide range of industrial and mobility solutions, improving durability and significantly reducing repair time and maintenance costs.<\/p>\n

This partnership combines Diab\u2019s 75 years of expertise in high-performance foam cores with CompPair\u2019s innovative HealTech\u2122 healable semi-products. Diab, a Swedish company, has long led the development and commercialisation of foam core materials for composite sandwich panels, while the Swiss company CompPair brings extensive experience in healable composites and their integration with various core structures. Since 2025, the two companies have collaborated to combine CompPair\u2019s healable skins with Diab\u2019s foam cores for applications where durability, repairability, and performance are essential.<\/p>\n

\u201cOur combined technologies unlock new levels of value for the composites industry,\u201d said Kai Arendholz, Group Business Development & Innovation Manager at Diab. \u201cWe are excited about the possibilities this brings to both aerospace structures as well as industrial and mobility applications.\u201d<\/p>\n

The collaboration has already validated the healing value of CompPair\u2019s HealTech\u2122 solutions and their compatibility with a wide range of sandwich structures using Divinycell foam cores, including HT (PVC), F (PES) and PR (PET) categories. Typical applications include aircraft interior panels, aircraft fairings, radomes, and sandwich body panels for trucks and caravaning. Common impact scenarios include hail and luggage impacts as well as tool drops, occurring during manufacturing or in service. The different use cases and healing methods have been validated through impact testing at various energy levels, mechanical testing and fire testing in line with industry requirements.<\/p>\n

Across these use cases, the material systems demonstrated strong and consistent technical performance, including effective healing behaviour, reliable skin adhesion with cohesive foam failure, and robust flammability performance. The ultra-fast repair procedure enables rapid restoration of structural performance, significantly reducing maintenance costs, downtime, and operational disruption, while also delivering environmental benefits through extended component lifetime.
\n\u201cThis partnership shows the powerful synergy between material innovation and repairability,\u201d said Ama\u00ebl Cohades, CEO of CompPair. \u201cTogether with Diab, we are pushing the boundaries of composite performance and durability.\u201d<\/p>\n

Highlighting the customer value, Bertrand Gresle, Sales Account Manager, added, “We are proud to partner with Diab, combining its proven track record of excellence with our healable composite solutions to answer the strong market demand and deliver tangible value to customers across multiple applications.\u201d
\nLooking ahead, Diab and CompPair will continue to advance new commercial applications of healable composite solutions, unlocking greater operational efficiency and enhanced material performance.<\/p>\n
