Carbon fiber sheet materials having improved dimensional stability and ease of handling are provided. The sheet materials include a carbon fiber network and an adhesive polymeric material adhered to at least one surface of the carbon fiber network. The invention further provides methods of making the carbon fiber sheet materials, as well as electrodes and electrical energy storage devices which include the carbon fiber sheet material as a component thereof.

The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim. A second facing sheet may also be mechanically integrated into an opposed surface portion of the cement core and contain a melt blown polymer web joined to one face. The present invention further includes a method of making the glass fiber facing sheet of the invention and a method of making a smooth cement board containing the glass fiber facing sheet of the invention.
