Abstract:
1. A process of continuously producing a more isotropic, electrically conductive composite composition, said process comprising: a) continuously supplying a compressible mixture comprising exfoliated graphite worms and a binder or matrix material, wherein said binder or matrix material is in an amount of between 3% and 60% by weight based on the total weight of the mixture; b) continuously compressing said compressible mixture at a pressure within the range of from about 5 psi or 0.035 MPa to about 50,000 psi or 350 MPa in at least a first direction into a cohered graphite composite compact; and c) continuously compressing said composite compact in a second direction, different from the first direction, to form said composite composition in a sheet or plate form.
