Filament Winding

Specially formulated adhesives are available for filament winding applications or for wrapping components such as hybrid rotor shafts for electric motors and high-voltage arresters. These adhesives are designed for materials such as CFRP (carbon fiber reinforced polymer) or GFRP (glass fiber reinforced polymer).

Filament winding process can be realized quickly and easily with UV adhesives. Hoenle offers a wide range of fast curing adhesive technologies that have unique properties to better meet the challenges of electric motor assembly. Adhesive properties include a wide range of elongation values, high Tg values for reduced movement and improved elasticity to meet the operational requirements of the stator, rotor and magnets under high temperatures, shock and vibration. The Hoenle adhesive portfolio is broad and includes 1- and 2-component epoxy resin adhesives as well as UV-, light- and dual-curing adhesives. They are particularly suitable for the various assembly and coating applications associated with the assembly of electric motors.
