A composite that includes an elastomer matrix into which carbon fibrils are incorporated. The fibrils are characterized as having a morphology consisting of tubes that are free of a continuous thermal carbon overcoat and have graphitic layers that are substantially parallel to the fibril axis, or as having a crystalline graphitic structure and a morphology defined by a fishbone-like arrangement of the graphite layers along the fibril axis.

Fibril-filled elastomer compositions

Products containing carbon fibrils having a morphology of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphitic layers, wherein the length of the projection of the graphitic layers on the fibril axis extends along the axis for a distance of at least two fibril diameters. The fibrils are used to form composites, adsorbents and mats.

Carbon fibrils

A volume of carbon fibrils that includes a multiplicity of fibrils having a morphology consisting of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphite layers that are substantially parallel to the fibril axis and a process for preparing such fibrils.
