Embodiment Construction

[0013] According to a first aspect, a method is disclosed comprising the steps of providing a composite tape comprised of a substantially rigid substrate having a major surface and a polymer overlying the major surface of the substrate. The method also includes forming the composite tape with the mandrel compound to form a shaped composite sheet having a shape substantially defined by the shape of the mandrel such that the major surfaces of the composite tape remain substantially in a plane during the forming step.

[0014] see figure 1 , figure 1 is a flowchart illustrating the steps of a chipless or near chipless forming technique for forming composite materials according to one embodiment. according to figure 1 , the process begins by providing a composite tape comprising a substantially rigid substrate and a polymeric coating. In one embodiment, the substantially rigid substrate comprises a metal, a metal alloy, or a combination thereof. Suitable metals for substantial...

Abstract

A process of forming a shaped composite material is provided which includes the steps of providing a composite strip having a substantially rigid substrate with a major surface and a polymer overlying the major surface of the substantially rigid substrate. The process further includes shaping the composite strip with a mandrel to form a shaped composite piece having a shape substantially defined by the shape of the mandrel, wherein during the shaping step the major surface of the composite strip is substantially maintained in one plane.

Description

technical field [0001] This disclosure relates generally to composite materials, and more specifically, to methods of forming shape-set composite materials. Background technique [0002] Composite materials have long been used in a variety of applications. Especially recently, composite materials are used as bearings. In general, a bearing is a mechanical component used to reduce friction. Bearings generally fall into two categories, linear or radial, in terms of the characteristics of the friction force that is reduced according to the bearing. Linear or thrust bearings are used in applications with motion along a straight line, such as moving drawers in and out. Radial or rotary bearings are used in applications involving motion about a central axis, such as a wheel on an axle. In addition, some bearings are designed to handle thrust and radial loads. [0003] Various types of materials can be used depending on the type of bearing desired for adequate friction reducti...
