Drone blades

Drone blades via Thermoforming

High-performance drone blades are produced by Thermoforming a TAFNEX™ Sandwich Panel with a foam core. In this process, the foam core and carbon fiber composite skin are usually integrated together rather than beforehand. By utilizing low-density foam cores, the resulting drone blades are exceptionally lightweight yet capable of enduring the forces and environmental conditions they encounter.
 

Improved collision safety through ductile failure behavior

TAFNEX™ Drone blades, made entirely from thermoplastic materials, respond to crashes with plastic deformations rather than brittle failure. This results in very small debris that disperses over a minimal area. Additionally, the fracture surfaces are not sharp-edged, making these blades significantly safer for people nearby in the event of an accident compared to thermoset carbon drone blades.
 

Drone blades via Injection Molding

In addition to press forming, TAFNEX™ Drone blades can be produced via Injection Molding using a TAFNEX™ Compound, which can include in-situ foaming. Ideal for high-volume production, this method also enables advanced design features – such as integrated leading-edge serrations for noise reduction. The injection-molded blade's mechanical performance can be boosted, if required, by adding local or full reinforcement with TAFNEX™ UD Tape.
