A method of making a coated abrasive article and the product thereof, involving the steps of: providing an endless spliceless backing loop substrate; applying fibrous reinforcing material onto a major surface of the endless backing substrate by applying of a first binder precursor to the fibrous reinforcing material such that the first binder precursor bonds the fibrous reinforcing material to the endless backing substrate to form a reinforcing fiber layer; further solidifying the first binder precursor; and forming an abrasive coating on the surface of one of the fiber reinforcing layer, or alternatively, the exposed surface of the backing substrate.
Disclosed is a transfer belt for an electro-photographic apparatus, comprising a seamless reinforcing layer made of a continuous string, and a semi-conductive rubber layer formed on the reinforcing layer.
A continuous fiber reinforced thermoplastic pipe coupling is disclosed having improved resistance to applied stress when used with pipe lengths being joined together. The fiber reinforcement is aligned during placement in a particular manner and placed at a predetermined fiber angles dictated mechanical forces being applied such as by internal fluid pressures in the coupled pipe lengths.
The present invention relates to a power transmission striated belt including an elastomeric matrix (21) and a lengthwise supporting structure consisting of polyamide 4.6 twisted strands (20). The supporting structure (21) is selected so that the stress-elongation diagram of the belt exhibits an average slope ranging from 12 to 20 daN/% of elongation per width centimeter. The twisted strands are wound with an almost null nominal tension, and the curing operation and the cooling operation after curing are carried out without any belt tensioning.
A belt for polishing a workpiece such as a semiconductor wafer in a chemical mechanical polishing system includes a polymeric layer forming an endless loop and having a polishing surface on one side of the endless loop. The belt is manufactured by molding a polymeric material such as urethane in a cylindrical mold. The belt is thus made from a single layer, reducing weight, size, cost and maintenance requirements.
An impact beam as subject of the invention comprises a polymer matrix and a metal reinforcing structure for impact reinforcement, which metal reinforcing structure comprises at least one woven fabric. The woven fabric comprises metal cords being essentially parallel to each other, and the metal cords are bond to the polymer matrix, so that a load can be transmitted directly between the polymer matrix and the metal cords.
