Abstract:
A nonwoven material is composed of a nonwoven batt of a plurality of bundles formed of carbon fibers. At least some of the bundles have a curved progression that includes a curved vertex area of a first curvature between the bundle ends and at least one bundle end area of a second curvature extending from said one bundle end to the vertex. The first curvature is greater than the second curvature, in particular it is greater by at least 50%.
