Topic: Plasma polymerization to demold carbon-fiber composites without using release agents.

High-tech for bicycle racing, environmentally responsible production: carbon-fibre composites removed from moulds without use of release agents

Use of carbon-fibre composites makes high-performance bicycles extremely light and strong. To reduce wind resistance, shapes must be designed to be absolutely aerodynamic. Bicycle frames are manufactured in a multi-layering process and then thermally cured in an autoclave.
Release agents are required to then remove these complex individual parts from the moulds. Residues of these release agents remain on the surface after demoulding and then must be removed in an elaborate process.
 Environmentally responsible demolding in modern bicycle production
Openair® Plasma combined with PlasmaPlus® is used to replace these release agents with a plasma polymer nano-coating that securely adheres to the mould. This means that no unwanted release agent remains on the surface when parts are removed from the mould.
In a subsequent step, the finished frames are completely scanned using a robot system and optimally prepared with RD1004 rotating plasma jets for the painting that follows. This also means that environmentally responsible, water-based paint systems can be used without any difficulty.
