Abstract
A composite material includes a matrix and carbon fibrous structures. The carbon fibrous structure has a three dimensional network of carbon fibers, each having an outside diameter of 15-100 nm, and has a granular part with which two or more carbon fibers are tied together such that the carbon fibers extend therefrom, and the granular part being produced in a growth process of the carbon fibers. The additive amount of the carbon fibers is in the range of 0.1 to 30% by weight of total weight of the composite material.
Claims14
A composite material comprising a matrix and carbon fibrous structures,
- wherein each of the carbon fibrous structures comprises a three dimensional network of carbon fibers each having an outside diameter of 15-100 nm, wherein the carbon fibrous structure further comprises a granular part, with which two or more carbon fibers are tied together such that the carbon fibers extend therefrom, and wherein the granular part is produced in a growth process of the carbon fibers, and
- wherein an amount of the carbon fibers added to the matrix is in a range of 0.1 to 30% by weight of a total weight of the composite material.
