The mat aspect of the invention comprises product and method for producing mats comprised of organic matting materials such as cellulose, paper, other wood products, or felt, and reinforcing fibers such as fiberglass, plastics, and other relatively high-strength natural and synthetic fibers, the fibers being incorporated within the matting material during production of the mat. The sheet aspect of the invention comprises product and method for mats of the type described above with added asphalt coatings to improve the water-proofing qualities of the mats.Type: ApplicationFiled: June 29, 1999Publication date: July 10, 2003Inventor: JOHN R. FIELDS

Publication number: 20030114071Abstract: A high pulp content nonwoven composite fabric is disclosed. The composite fabric contains 1) from more than about 0 to less than about 30 percent, by weight, of a nonwoven layer of conjugate spun filaments, the filaments containing at least one low-softening point component and at least one high-softening point component and having at least some exterior surfaces of the filaments composed of at least one low-softening point component; 2) more than about 70 percent, by weight, of pulp fibers; and 3) regions in which the low-softening point component at the exterior surfaces of the filaments is fused to at least a portion of the fibrous component. This high pulp content composite nonwoven fabric may be used as a heavy duty wiper or as a fluid distribution material, cover material, and/or absorbent material in an absorbent personal care product. Also disclosed is a method of making the high pulp content nonwoven composite fabric.Type: ApplicationFiled: September 9, 2002Publication date: June 19, 2003Inventors: Cherie Hartman Everhart, Danial Owen Fischer

Patent number: 6558765Abstract: A fiber reinforced composite wood board is designed particularly for use in the flooring of truck trailers which experience adverse operating conditions such as from heavy loads of lift trucks on the top side and water spray during rainy periods on the bottom side. The composite wood board comprises an edge-glued laminated wood member composed of wood segments with end joints. The wood member is underlaid with a thin layer of fiber reinforced plastic. The top surface of the composite wood board is the same as that of the laminated wood. The fiber reinforced plastic underlay is composed of glass and/or carbon fibers embedded in a polymeric resin such as epoxy, phenolic, vinyl ester, polyester, polypropylene or polyamide resin. Further, the fiber reinforced plastic underlay is substantially bonded to the wood member with a reactive hotmelt adhesive.Type: GrantFiled: December 7, 2000Date of Patent: May 6, 2003Assignee: Havco Wood Products L.L.C.Inventor: Gopalkrishna Padmanabhan

Patent number: 6558766Abstract: A fiber reinforced composite wood flooring is designed particularly for use in van-type truck trailers which experience adverse operating conditions due to heavy lift truck traffic on the top side and water spray during rainy periods on the bottom side. The composite wood flooring comprises edge-glued laminated wood which is underlaid with a thin layer of fiber reinforced plastic. The top surface of the composite wood floor is the same as that of a conventional laminated wood floor. The fiber reinforced plastic underlay is composed of glass and/or carbon fibers embedded in a polymeric resin such as epoxy, phenolic, vinyl ester, polypropylene or polyamide resin. The fiber reinforcement is designed to enhance the mechanical properties of the flooring in the longitudinal and transverse directions of the floor. The fiber reinforced plastic improves the fatigue resistance of the composite wood flooring and prevents water leakage into the trailer through the floor boards.Type: GrantFiled: December 7, 2000Date of Patent: May 6, 2003Assignee: Havco Wood Products L.L.C.Inventors: Gopalkrishna Padmanabhan, Lokeswarappa R. Dharani, James N. Vangilder
