Thermoplastic composites maker Rein4ced files for bankruptcy
Rein4ced, the Belgian thermoplastic carbon fibre and composites manufacturer, has filed for bankruptcy, marking a serious setback to European carbon fibre frame and component production.
In a LinkedIn post, Rein4ced co-founder Michaël Callens said the company "ran out of options" at the end of December and confirmed the bankruptcy filing, adding that the team had pushed thermoplastic composite technology forward but lacked the time to "show its potential in other products and markets", such as aerospace and defence.
Rein4ced was founded to bring carbon frame manufacturing to Europe and reduce reliance on Asian supply chains, and secured backing from institutional investors to open its automated plant in Herent, Belgium, in 2019. In 2020, it won a flagship deal to produce carbon frames for Accell Group, the company behind brands such as Lapierre, Haibike and Raleigh, and last year it collaborated with Focus on the Jam² Next thermoplastic carbon fibre mountain bike.
Rein4ced's financial results from 2024 show the business never reached profitability. It reported losses of some US$25.8 million from 2021 to 2024, and its assets decreased from US$9.8 million in 2021 to US$68,000 in 2024, while its revenue stayed low or non-existent. In the five years of operating, the company also had several leadership changes and capital injections, the last of which was US$817,000 in November 2025.
