|---|
| 442101000 | Coating or impregnation is anti-slip or friction-increasing other than specified as an abrasive | 6 |
| 20080254697 | WET TYPE FRICTION MEMBER AND MANUFACTURING METHOD FOR THE SAME - A friction plate | 10-16-2008 |
| 20090036010 | FRICTION MATERIAL WITH SILICON - One embodiment includes a product including a friction material including a mat including a plurality of fibers including carbon fibers, and a silicon component including at least one of silicon carbide, silica, silicon or other silicon-based compounds. | 02-05-2009 |
| 20100056004 | Skid resistant roof underlayment - A flexible, non-skid roof underlayment is provided which is formed from a spunbond nonwoven layer of continuous multiple component filaments and a coating on at least one surface of the spunbond nonwoven layer. The spunbond filaments are preferably formed in a sheath-core configuration with a high strength component in the core and a sheath component having high adhesion to the coating. The roof underlayment has an improved combination of high tensile strength and high coefficient of friction. | 03-04-2010 |
| 20110151735 | INDUSTRIAL FABRIC WITH TRACTION COATING - An industrial fabric used in the manufacture or processing of at least one material web includes a base fabric having a board side and a machine side. The base fabric includes a plurality of spirals extending in a cross machine direction (CMD). The spirals are interconnected together with each other along adjacent peripheral edges to form a spiral link fabric. The base fabric has opposite lateral side edges extending in a machine direction (MD). One or more electrostatic control yarns are positioned within a corresponding spiral and extend in the CMD direction to the lateral side edges. A pair of conductive edge coatings is applied to at least the board side of a respective lateral side edge for a predetermined width. The conductive edge coatings and the one or more electrostatic control yarns form an electrostatic grid. A traction coating covers substantially all of at least the board side of the base fabric, but does not cover the pair of conductive edge coatings. The traction coating has a coefficient of friction greater than approximately 2 on the board side. The industrial fabric has a completely non-marking seam because of its integral nature with the base fabric and the equal amount of traction coating at the seam compared with rest of the fabric. | 06-23-2011 |
| 20150368856 | COMPOSITE FRICTION MATERIALS HAVING CARBON NANOTUBE ANDCARBON NANOFIBER FRICTION ENHANCERS - A textile-reinforced composite friction material is provided by the present invention that includes a nonwoven needlepunched fiber mat, a resin matrix impregnated within and onto the fiber mat, and a carbon nanomaterial dispersed within the resin matrix. The carbon nanomaterial is preferably carbon nanotubes and/or carbon nanofibers. | 12-24-2015 |
| 20160153137 | COMPOSITE FRICTION MATERIALS HAVING CARBON NANOTUBE ANDCARBON NANOFIBER FRICTION ENHANCERS | 06-02-2016 |
