Innovating for circularity
SOLUTIONS
HealTech™ is a thermoset-based resin system giving FRPs the ability to heal cracks and delaminations in 1 minute by locally heating the part in a range of 100°C-150°C. HealTech™ is suitable for autoclave, out-of-autoclave, and press curing, and in a range of composite processes. CompPair is continuously innovating and creating solutions compatible with extended composite applications.
Composite Solutions
Prepregs
CompPair provides pre-impregnated textiles with various reinforcement types and resin systems adapted to autoclave, out-of-autoclave and press processing. On top of our two current resin systems (CS01 and CS02), the team can support the implementation of bio-based systems, fire resistant and slitted tape systems.
The HealTech™ CS01 system enables the production of healable composites with a high toughness, very low porosities, and very limited exothermal reaction during the cure.

CompPair's healable systems are available for infusion manufacturing, provided as fibre-resin systems. Upon request, custom systems such as bio-based and RTM systems can be implemented.
OTHERS
Our carbon and glass prepregs can be used for tube manufacturing and delivered directly as tubes.
Our carbon and glass systems can be used for continuous sheets manufacturing.
Our healable systems brings an easy repair solution to sandwich panels through the use of adhesive films, repairing dents and delaminations. Compatible cores includes foams such as PET, PVC, XPS or PU, as well as some honeycomb core applications.
With all our resin systems, we can provide monolithic carbon and glass plates that can be used for further processing. The repair of our composites reduces residual stresses and porosities, enabling high precision machining and drilling/milling.
All of CompPair's semi-products can be transformed into the semi-finished part presented below.
Our solutions are designed to provide benefits under static and fatigue damage use cases, while keeping competitive mechanical performances. The CompPair team can support the quantification of specific healing benefits for your application.
Technology
Fatigue damage recovery
The graph above displays the performance of standard composites versus HealTech™ composites, when subjected to fatigue. HealTech™ extends lifetime, reduces failure risks, and keeps constant properties, thanks to regular healing and preventive healing cycles.
Benchmark composites
HealTech™ composites
Static damage recovery
As shown in the graph above, the performance of HealTech™ composites, in response to stress and strain is superior to the performance of benchmark composites. While damaged composites show reduced modulus and strength compared to a virgin sample, healed HealTech™ composites regain initial mechanical properties.
