Delta Core

The composite Carbon Nanotubes design was taken as a basis by the laboratories of the Fraunhofer Technology Development Group, where the arrangement of the molecules was further enhanced. The main innovation of the Delta Core material is the delta-shaped arrangement of the individual molecules, which permits a more finely meshed network. The tube structure is retained; it is simply made more compact and solid. The Delta Core material can be processed very finely, and thanks to optimised racquet production processes, it can be used throughout the racquet frame.
