摘要:
A high strength, low friction engineered material includes a low friction material filling interstices of a metal microlattice. The metal typically comprises 5 volume % to 25 volume % and the interstices typically comprise 75 volume % to 95 volume %, based on the total volume of the metal microlattice and the interstices. The low friction material preferably fills 100 volume % of the interstices. The metal microlattice can be formed of a single layer, or multiple layers, for example layers of nickel, copper, and tin. The low friction material is typically a polymer, such as polytetrafluoroethylene (PTFE), polyamide (PAI), polyetheretherketone (PEEK), polyethylene (PE), or polyoxymethylene (POM). The low friction material can also include additive particles to modify the material properties. The engineered material can be used in various automotive applications, for example as a bearing, or non-automotive applications.

A tolerance ring with functional layers has an annular band and an elastomeric layer. The assembly also may have a low friction layer, which may be bonded, calendared or laminated thereto. The low friction material may completely encapsulate the annular band.

[Problem] As a multi-layered sliding member aimed at applications in high temperature regions, there has been proposed slide sheet components each having a metal mesh component such as an expanded metal or wire mesh and an expanded graphite integrated therewith, but a problem remains in the strength when applied to sliding members such as bearings, allowing only a limited range of applications. It is therefore a subject of the present invention to provide a multi-layered sliding member suitable for applications under high temperatures under which lubricating oils or synthetic resins are not adoptable, and to provide a method of manufacturing the same. [Solving Means] A multi-layered sliding member 7 of the present invention has a metal mesh component 5 such as a expanded metal 50, integratedly bonded to the surface of a back metal 3 while placing in between a porous sintered bronze layer 4 integratedly bonded to the back metal 3, and an expanded graphite 8 formed so as to fill the openings of the metal mesh component 5 and so as to cover the surface of the metal mesh component 5.

摘要:
Procédé de fabrication d'un matériau en feuille présentant un faible coefficient de frottement, à partir d'un empilement d'une nappe de métal déployé et d'au moins un ruban de polytétrafluoroéthylène (PTFE), par compression et chauffage. Il est caractérisé par le fait que l'on procède d'abord à un calandrage de l'empilement (1, 2, 3), puis à un chauffage de l'empilement calandré (1, 2, 3) pour réaliser le frittage du PTFE (1, 3).
