Thermoplastic composite aircraft sidewall panels using recycled carbon fibre

The company of the Cannon Group, Cannon Ergos, is working with Boeing on moulding trials for the feasibility of using recycled carbon fibre (rCF) for the fabrication of aircraft cabin interior sidewall panels. The recovery and reuse of carbon fibre waste during production processes and end-of-life applications, such as automotive and aeronautics, has proved to be economically viable. This supports the implementation of the EU Waste Framework Directive (2008/98/EC) to greatly reduce landfill disposal which is environmentally essential and is also in line with targets set by the EU Circular Economy Package for sustainable production practices.

“For several years, together with sister companies Cannon Afros and Cannon Tipos, we have successfully undertaken numerous projects that offer new life to recycled carbon fibre. By combining various technologies and production processes tailored for each application, we have been able to effectively process recycled carbon fiber whether impregnated with diverse resins, or already integrated within a thermoplastic matrix. The project with Boeing demonstrates the viability of fabricating interior sidewall panels with high-performance thermoplastics reinforced with recycled carbon fibre”, said Mattia Andolfatto, Project Manager R&D at Cannon Ergo.

The project’s latest stage involves Mitsubishi Chemical Advanced Materials (MCAM), a global supplier of high-performance reinforced polymers for which Cannon Ergos has designed, manufactured, and installed a customized and fully equipped thermo-compression unit. This equipment was utilized to produce prototype sidewall panels with the new Kyrontex material. Typical resin matrices utilized for Kyrontex thermoplastic composite aeronautical applications include PA, PEI, PPS, PEEK and PAEK.
