Title: (EN) Flat plate-like ribbed porous carbon material and manufacturing method therefor
Abstract: front page image
(EN)

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).
