Complex 3D-Filament Winding for CFRP and Hybrid Materials

What is the Purpose of Filament Winding?

Filament winding is an automated, high quality production process utilizing an impregnated roving (e.g. carbon fiber or glass fiber) which is laid on a rotating core and thereby forming a composite vessel, pipe or any rotation-symmetric fiber composite part. Innovative and new complex 3D-Winding procedures increase the process possibilities avoiding the need of a rotating core, by which the one shot production of innovative composite frameworks can become reality beyond known limits. By combining local 3D-CFRP-reinforcement with metallic structures and sub structures a better performance at low investment and production cost is achievable.

Which New Opportunities are given by Filament Winding Processes?

Filament winding builds up unidirectional, non-crimp layers by forming high performance composite parts directly from the fiber coil. This characteristic enables low cost composite solutions due to lowering scrap costs and a minimal use of CRFP with high productivity. Process variables such as geometry, filament deposit path, filament spread have to be coordinated to achieve maximum efficiency.

The possibilities of 3D-Winding exceed standard winding procedures by far. Current 3D-Filament-Winding methods are neither limited to rotationally symmetrical or lost core designs. Through extensive process and tool know-how innovative winding solutions for the construction of CFRP-Components with low material usage and optimal load handling are being developed by CIKONI composites innovation.
