Abstract
A ribbed porous carbon material (1) is a one piece molded product containing carbon fibers (5) and having a rib portion (2) and a web portion (3), in which the carbon fibers (5) are oriented in the rib portion (2) along the direction of the thickness of the web portion (3), while the carbon fibers (5) are oriented in the web portion (3) along the direction of the plane of the web portion (3) and along the direction perpendicular to the rib portion (2).
Claims16
A ribbed porous carbon material containing carbon fibers and having a rib portion and a web portion, in which the carbon fibers in the web portion are oriented along a direction of a plane of the web portion and along a direction perpendicular to a longitudinal direction of the rib portion, and wherein the carbon fibers in the rib portion are oriented along a direction of a thickness of the web portion.
A ribbed porous carbon material as in claim 11, wherein a specific electric resistivity of the web portion along a direction of a thickness thereof is not greater than 40 m.OMEGA.. cm.
A ribbed porous carbon material as in claim 11, wherein a ratio of a specific electric resistivity of the web portion along a direction of a thickness thereof to a specific electric resistivity of the rib portion along a direction of a height thereof is not less than 1.2.
A ribbed porous carbon material as in claim 12, wherein a ratio of a specific electric resistivity of the web portion along a direction of a thickness thereof to a specific electric resistivity of the rib portion along a direction of a height thereof is not less than 1.2.
A ribbed porous carbon material as in claim 11, wherein a ratio of a bending strength of the web portion along a direction parallel with the longitudinal direction of the rib portion to a bending strength of the web portion along a direction perpendicular to the longitudinal direction of the rib portion is from 1.2 to 10.
A ribbed porous carbon material as in claim 11, wherein the rib portion and the web portion are integrated into one-piece molded product.
