A fiber blend for use in friction materials. The fiber contains a blend of a highly fibrillated fiber, such as a fibrillated polyacrylonitrile fiber and a fiber with a high carbon content, such as an oxidized carbon fiber precursor.

A reinforcement system for mastic intumescent fire protection coatings. Free floating hybrid mesh embedded in the coating is used to reinforce the coating. The hybrid mesh is made from a combination of high temperature and low temperature yarns.

Reinforcement system for mastic intumescent fire protection coatings

A method of manufacturing controlled electrical resistivity carbon fiber sheet products employing a carbonizable starting material, heating and drawing the starting material (if required,) oxidizing the starting material at an elevated temperature of the order of 220 degrees Centigrade to effect molecular aromatic rearrangement of the starting material, carbonizing the oxidized starting material at an elevated temperature in an oxygen free atmosphere within a furnace having an elevated temperature extending over a temperature range to about 1400 degrees Centigrade by soaking the starting material at an elevated temperature for a predetermined period of time to provide a preselected electrical resistivity to the carbonized material. The carbonized material thus treated is formed into end carbon fiber sheet products having the form of paper, woven fabric and the like having a desired electrical resistivity. The starting carbonizable material consists essentially of PAN.
