AIRPOXY is thermoformable, repairable, and bondable smart epoxy based composites for aerostructure
About AIRPOXY
WHAT?
The aim of AIRPOXY is to reduce the production and maintenance costs of composite parts in the aeronautic sector by introducing a novel family of ground-breaking thermoset composites that preserve all the advantages of conventional thermosets, but can also be easily processed and repaired, and even recycled.
HOW?
This is will be achieved by the further development and validation of a family of ground-breaking thermoset resins which present reversible or “dynamic” bonds, recently developed by CIDETEC (patent pending). These dynamic chemical bonds enable a series of “smart” properties, creating a new generation of thermoset composites that preserve their high performance, in terms of easy fibre impregnation and overall stability, while showing new unprecedented features once the composite is completely cured, such as Re-processability, Reparability and Recyclability (3R).
The new generation 3R epoxy composites developed in AIRPOXY will enable:
- High production rates due to new innovative 3R-Thermoforming processes
- More robust and cheaper chemical 3R-Bonding technology
- Easy cost-efficient 3R-Repair method for rejected or damaged parts
- Recycling of manufacturing or end of life (EoL) waste will be possible closing the loop and achieving true sustainability
The developed technology will be moved from TRL3 to TRL5 through two representative demonstrators of aircraft panels.
HOW MUCH?
Thermoforming processes will reduce manufacturing cost of carbon composites parts by 35% in comparison to autoclave manufacturing, reducing processing times from hours to minutes. In addition, a novel welding process will reduce CC bonding costs by up to 50%.
AIRPOXY has received 6,5 Million € of funding from European Union’s Horizon 2020 research and innovation programme under grant agreement N° 769274. The project duration is 42 months.
WHO?
AIRPOXY relies on a multidisciplinary consortium of 11 partners from 6 European countries and is coordinated by CIDETEC.

AIRPOXY Objectives
- Bring the Technology Readiness Level (TRL) of a new family of 3R thermoset resins from TRL3 to TRL5 for aircraft applications
- Reduce manufacturing costs of thermoset carbon composites parts by over 35% in comparison to autoclave manufacturing
- Reduce repair, maintenance and overhaul operations (RMO) costs for reparation or replacement of thermoset carbon composites parts by 50%
- Reduce costs of adhesive bonding of thermoset carbon composites parts by over 50% and increase robustness by 20%.
- Quantify the environmental advantages of the recyclability of 3R carbon composites parts at end of life in comparison to traditional carbon composites parts
- Ensure efficient dissemination and future exploitation of the developed 3R technologies to reach TRL9 after the project’s lifetime
AIRPOXY Approach
AIRPOXY will cover the entire value-chain to solve manufacturing process cost-effectiveness challenges.
To achieve this, AIRPOXY gathers a multidisciplinary consortium of 11 strategic partners from 6 European countries ensuring adequate progress of the technical core activities and the proper validation of the resulting demonstrators.
The AIRPOXY work plan includes two main technical phases:
- Upgrading 3R technologies from TRL3 to TRL4.
- Validation of the technologies in industrial environment to reach TRL5 by manufacturing and testing two demonstrators: 1) a sub-component of a FAN-COWL formed by a skin, a transverse stiffener and a longitudinal stiffener, and 2) a sub-component of a LEADING-EDGE formed by a nose and two webs.
