Abstract
A racket may include a frame including at least one prepreg layer. The at least one prepreg layer may include reinforcing fibers. The at least one prepreg layer may also include a matrix at least partially surrounding the reinforcing fibers. The at least one prepreg layer may also include graphene material.
Claims26
A racket, comprising:
- a frame including at least one prepreg layer, the at least one prepreg layer including:
- reinforcing fibers,
- a matrix at least partially surrounding the reinforcing fibers, and
- graphene material;
- wherein the graphene material is dispersed throughout the matrix and the graphene material includes at least one of particles or flakes.
