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.
Claims18
An anti-wear composite structure comprising:
- an anti-wear layer having a wear surface opposite an adhesive receiving surface, the wear surface being configured for sliding engagement with a mating surface;
- and
- a layer of thermoplastic adhesive tape applied to the adhesive receiving surface;
- wherein the layer of thermoplastic adhesive tape is configured to removably bond the anti-wear composite structure to a substrate at a temperature of about 138 degrees Celsius (280 degrees Fahrenheit) to about 160 degrees Celsius (320 degrees Fahrenheit).
An anti-wear composite structure comprising:
- an anti-wear layer having a wear surface opposite an adhesive receiving surface, the wear surface being configured for sliding engagement with a mating surface;
- and
- a layer of thermosetting resin adhesive applied to the adhesive receiving surface;
- wherein the layer of thermosetting resin adhesive comprises a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion, having an onset to cure in the ambient temperature band and having a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to the substrate;
- wherein the layer of thermosetting resin has a premature curing temperature of zero degrees Celsius (32 degrees Fahrenheit) below which the thermosetting resin does not prematurely cure.
An anti-wear composite structure comprising:
- an anti-wear layer having a wear surface opposite an adhesive receiving surface, the wear surface being configured for sliding engagement with a mating surface;
- and
- a layer of thermosetting resin adhesive applied to the adhesive receiving;
- a protective layer removably adhered to the anti-wear layer and configured to be removed before or after bonding and before use in a service application;
- a release layer removably adhered to the layer of thermosetting resin adhesive, the release layer being configured to be entirely removed from the layer of thermosetting resin adhesive prior to bonding to the substrate;
- wherein the layer of thermosetting resin adhesive comprises a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion, having an onset to cure in the ambient temperature band and having a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to the substrates;
- wherein the layer of thermosetting resin has a premature curing temperature of zero degrees Celsius (32 degrees Fahrenheit) below which the thermosetting resin does not prematurely cure.
