The Swiss engineering and technology company CompPair Technologies (hereinafter referred to as CompPair) was founded in 2020. The company is committed to researching and developing self - repair technology for composite materials. This technology is an innovative thermosetting resin technology that can quickly repair the damaged parts of fiber - reinforced composite materials by heating.

CompPair is a spin - off company from the Swiss Federal Institute of Technology in Lausanne, founded by Amael Cohades and Robin Trigueira. Amael Cohades is the CEO of the company. He holds a doctorate in materials from the Swiss Federal Institute of Technology in Lausanne, has authored 18 papers, and has served as a consultant for the JEC Group, an internationally leading composite materials network. Robin Trigueira is the CTO of the company. He holds a master's degree in materials science and engineering from the Swiss Federal Institute of Technology in Lausanne and has served as a research assistant in the Advanced Composite Materials Processing Laboratory at the Swiss Federal Institute of Technology in Lausanne.

Composite materials are widely used in industries such as aerospace, wind energy, and sports. Currently, the global market size reaches 100 billion US dollars. However, the use of these materials shows obvious wear and tear. Their repair and replacement may lead to problems such as equipment downtime or unsatisfactory repair effects. There is also no effective way to recycle the discarded composite materials due to performance degradation. It is estimated that by 2026, the losses caused by the wear and tear and discarding of composite materials will reach 22 billion US dollars. Currently, the trend in the composite materials industry is shifting from mainly focusing on recycling to emphasizing repair and maintenance. As a more sustainable and practical solution in the short and medium term, the market size of composite material repair is estimated to exceed 20 billion US dollars.

CompPair has developed a self - repair technology for composite materials. This technology allows the damaged parts of composite materials to quickly self - repair through heating, restore their initial performance, and extend their service life. Currently, it has been applied in multiple fields such as aerospace, outdoor sports, and high - end consumer goods.

CompPair has developed a proprietary technology, HealTech™, which is a thermosetting resin technology. It enables fiber - reinforced composite materials to activate the resin in the damaged area through local heating (100°C - 150°C) and undergo a phase change, allowing the cracks and scratches to re - bond and fill. After cooling, the material returns to its initial performance state. It is suitable for autoclave curing, non - autoclave curing, and press curing processes and is compatible with various composite material manufacturing processes.

HealTech™ can significantly improve the performance, service life, and repair speed of composite materials. This technology can increase the crack resistance of composite materials by 30%, enhancing the toughness and strength of the materials; it can increase the material damping by 80%, enabling the materials to maintain stable performance throughout their entire service life cycle. HealTech™ allows fiber - reinforced composite materials to complete self - repair within 1 minute, which is 400 times faster than the conventional repair technology in the industry. Its repair rate is as high as 100%, and the number of self - repairs can reach more than 60 times. It is suitable for various problems such as delamination, micro - cracks, and scratches.

With the HealTech™ technology, CompPair currently mainly provides pre - impregnated textiles, liquid molding products, and some semi - finished products such as sandwich panels and pipes. Its pre - impregnated textiles can use a variety of reinforcing materials, such as carbon fiber, glass fiber, recycled carbon fiber, and natural fiber. They are suitable for autoclave, non - autoclave, and press processing, featuring high toughness, extremely low porosity, and extremely low heat release during the curing process. Its liquid molding products are mainly provided in the form of HealTech™ fiber resin.

CompPair's technologies and products can be applied in multiple industries such as aerospace, outdoor sports, and high - end consumer goods. In the aerospace field, CompPair has cooperated with ESA (European Space Agency) to jointly develop aerospace pre - impregnated products for low - temperature applications and explore the application of self - sensing and repair technologies in the space field; the company has also cooperated with the glider company Altus to develop wheel covers, solving the problems of easy damage during take - off and landing and waste caused by frequent replacement. In the outdoor sports industry, CompPair has cooperated with Decathlon and Salomon in the development of materials for sports shoe soles, ski boards, etc., and has cooperated with ZESST and Gunboat to develop components such as hydrofoils and sandwich panels for marine boats. In the high - end consumer goods field, the dials, decorations, and bezels of the Swiss watch brand ID Genève all use the company's pre - impregnated products.

In March 2021, CompPair completed a seed - round financing of 950,000 Swiss francs, with investors being Thomas Rauber and Christian Fischer. In December 2023, the company completed a new round of financing, with investors including institutions such as InnoSuisse and Eurostar. In the future, the company will continue to improve its technical capabilities and continuously expand its customer base in the composite materials industry.
