Abstract:
Methods of making a graphite material are provided. A flexible graphite is ground into a powder. The graphite powder is mixed with a resin and the mixture is hot pressed. A second method of making a graphite material is provided where the graphite is ground into a powder; the graphite powder is soaked in a cryogenic liquid; the soaked graphite powder is then expanded; the expanded soaked graphite powder is mixed with a graphite powder; and the graphite powder mixed with a resin are hot pressed. According to a third method, the flexible graphite is ground into a powder; the graphite powder is soaked into a cryogenic liquid, the soaked graphite powder is expanded; and the expanded soaked graphic powder is ground into a fine powder. The resulting graphite powder is mixed with a resin. The graphite powder mixed with the resin is hot pressed. According to a fourth method, graphite flakes are soaked into an acid; the soaked graphite flakes are expanded; and the expanded soaked graphite flakes are precompacted. The precompacted soaked graphite flakes are ground into a powder. The ground precompacted expanded soaked graphite powder is then mixed with a resin. The graphite powder with the resin is hot pressed.
Abstract:
Formable mixture of flexible graphite sheet particles having embedded ceramic fibers extending into the particles from the particle surfaces to increase the permeability of the sheet to resin.
Abstract:
Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties.

Abstract:
This invention relates to a method for producing a lightweight graphite molding excellent in elasticity, which comprises mixing elastic graphite particles as the aggregate with a binder resin in such a manner that the resin adheres to the surfaces of the graphite particles in spiderweb form prior to molding.
Abstract:
The invention relates to a process for producing graphite particles to be used widely as highly functional graphite material, which comprises applying ultrasonic waves to a liquid containing dispersed therein expanded graphite particles to thereby produce fine flaky graphite particles with a high aspect ratio and well-developed anisotropy without forming secondary particles. Moldings of the obtained graphite particles show high electric and thermal conductivities.

Abstract:
A thermal management matrix (1) for an electrochemical cell array including a plurality of electrochemical cell elements, the thermal management matrix at least in part enveloping the electrochemical cell array and being in thermal contact therewith. The thermal management matrix includes mainly expanded graphite, wherein the expanded graphite is arranged in the form of a block- like structure and the block includes at least one layer of expanded graphite having a higher in-plane thermal conductivity than the layers neighboring the layer with higher in-plane thermal conductivity. The thermal management matrix may also include phase change materials as a latent heat storage material.
Abstract:
Monolithic gravity-laid inorganic fiber webs that are greater than about 5 cm in thickness are disclosed. Methods of making and using such webs are also disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a monolithic thick web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.
