CompPair has developed a unique self-healing composite technology to reduce maintenance costs, reduce manufacturing defects and extend the lifetime of composites. The result of 12 years of research at EPFL in Switzerland, HealTech™ is a new type of resin giving composite materials the ability to heal cracks and delaminations in a few minutes. Made with HealTech™, composite structures can be fully repaired on site as the parts stay structural during healing.
Delaminations and porosities are healed autonomously in 1 to 5 minutes by heating the part at a temperature between 100°C and 150°C.
Parts can be repaired more than 60 times without losing their mechanical properties nor their healing capability.
The products from CompPair have a standard drapability, tack and curing process and are easily processed.
CompPair technology meets benchmark composite performances and stays structural during healing, no mold or pressure needed. CompPair composites have a toughness (i.e. crack resistance) in average 30% higher than benchmark ones.
CompPair technology allows a better recycling of the fibers, keeping most of their properties.
Repaired parts recuperate 100% of their mechanical properties while keeping their weights and profile unchanged.

CompPair wishes to offer prepregs with the lowest impact on the planet. To reduce the impact of the fibres in semi-product prepregs the company is providing sustainable fibre options.
When a composite part made with HealTech™ prepregs has been damaged, the repair is simple and fast.
Standard tools needed for a 2 minute in-situ repair:
Repair method:
Impact damage representative of a real part application
Impact fully healed in 3 minutes simply using a heat gun
