Abstract
An anti-wear composite structure includes an anti-wear layer that has a wear surface opposite an adhesive receiving surface and a thermosetting resin applied to the adhesive receiving surface. The thermosetting resin includes a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion. The thermosetting resin has an onset to cure in the ambient temperature band and has a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to a substrate.
Claims21
A method of applying an anti-wear composite structure to a substrate, the method comprising:
- providing an anti-wear composite structure comprising an anti-wear layer having a layer of thermosetting resin applied to an adhesive receiving surface of the anti-wear layer, and a wear surface opposite the adhesive receiving surface, the wear surface being configured for sliding engagement with a mating surface;
- maintaining the anti-wear composite structure at a temperature below an ambient temperature band of 72 degrees Fahrenheit plus or minus 15 degrees Fahrenheit before installation to prevent premature curing of the layer of thermosetting resin;
- adhering the layer of thermosetting resin to the substrate via pressure-sensitive adhesion at the ambient temperature band;
- applying pressure to the anti-wear composite structure;
- and
- heating the anti-wear composite structure to a temperature sufficient to cure the layer of thermosetting resin and mechanically and chemically bond the layer of thermosetting resin to the substrate.
