Abstract
It has now been found that highly advantageous three-dimensional, macroscopic assemblages of randomly oriented carbon fibrils can be prepared which have relatively uniform physical properties along one, preferably two and most desirably three-dimensional axis of the three-dimensional assemblage. Preferred compositions prepared according to the methods of the invention have uniform physical properties along at least one dimensional axis and have relatively isotropic physical properties in at least one plane of the assemblage and most desirably are isotropic throughout the entire three-dimensional structure.
