Abstract

A composite material includes a ceramic matrix and two different fractions of fiber bundles, namely a reinforcing fiber bundle fraction and a matrix fiber bundle fraction having different average fiber bundle lengths. The fractions of fiber bundles are separated in a total fiber bundle distribution relative to a fiber bundle length by a minimum. A method for manufacturing a composite material and a method for manufacturing elements formed of a composite material are also provided.
