CompPair has developed a unique self-healing technology to reduce maintenance cost, 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.
