A laminate structure and method of forming is provided. The laminate structure includes a first metal sheet having a first thickness, a second metal sheet having a second thickness, and an adhesive core having an adhesive thickness. The adhesive core is disposed between and bonded to the first and second metal sheets. The first and second metal sheets are made of an aluminum based material and the adhesive core is made of an adhesive material also described as a viscoelastic adhesive material. The laminate structure is configured such that a ratio of the sum of the first and second thickness to the adhesive thickness is greater than either to one (8:1). The laminate structure including the viscoelastic adhesive core is characterized by a composite loss factor at 1,000 Hertz which is continuously greater than 0.1 within a temperature range of 25 degrees Celsius to 50 degrees Celsius.

Laminate including aluminum sheets

The teachings herein are related to assemblies, such as oil pan assemblies, including a laminate bottom portion and a nut attached to the laminate bottom portion. The nut may provide a sealable opening to a cavity of the assembly. The laminate bottom portion preferably includes a polymeric layer sandwiched between two metallic layers. The nut preferably is a clinch nut.

Oil pan assembly including laminate and clinch nut

A laminate sheet including a weldable margin is formed by laminating metal sheets having a core layer disposed therebetween. The core layer is formed of a core material which includes one or more of a viscoelastic, adhesive and acoustic material. The core layer is selectively distributed such that the laminate sheet includes an adhered region providing a laminate structure, and a non-adhered region including a weldable margin. The non-adhered region is adjacent an edge of the core layer and is characterized by a gap between the first and second metal sheets and by an absence of the core layer in the gap. The non-adhered region defines a weldable margin adjacent a core edge configured such that a weld is formable in the weldable margin without heat affecting the core layer. The laminate sheet can be joined by fasteners installed in the non-adhered region.

The teachings herein relate to improved composite materials offering weight reduction which are capable of withstanding automotive paint bake ovens.

Composite materials, vehicle applications and methods thereof

Disclosed herein are articles having an edge that is partially, or entirely sealed with one or more coatings including a polymeric material. The article may include a coating selected so that one surface (e.g., a face surface) has a desired property (e.g., an appearance, such as a chrome appearance), and a second surface (e.g., a different face surface, or an edge surface) is covered with a different material, where the different coatings provide protection to at least the edge surface. Also disclosed are coating materials including a tracer component. Also disclosed are methods for coating a substrate. Also disclosed are methods for confirming the presence of a coating, particularly on an edge surface.

Composite materials having a coated edge and methods thereof

The present invention provides a bimetal laminate structure and improved method for manufacturing the same. The method includes: applying a layer of adhesive to a metallic substrate; and laminating a decorative metallic sheet to the metallic substrate in such a manner that substantially all surface defects and all read through appearance along an outer surface of the decorative metallic sheet are eliminated. The resultant bimetal laminate includes a decorative metallic layer consisting of a first metallic material, and a metallic substrate consisting of a second metallic material that is different from the first metallic material. The metal substrate has a thickness that is greater than the thickness of the decorative metallic layer. An adhesive layer is disposed between, and spans substantially the entirety of the decorative metallic layer and metallic substrate to rigidly attach the same.

Bimetal laminate structure and method of making the same

A damped windage tray for an engine including a windage tray formed from a laminate. The laminate operates to damp vibrations of the windage tray. The laminate includes a first constraining layer, a second constraining layer and a viscoelastic damping layer disposed between the first and second constraining layer. The viscoelastic damping layer spans substantially the entirety of the first and second constraining layers. Additionally, a method of forming the windage tray is provided.

Damped windage tray and method of making same

A coated metal article includes a ferrous metal substrate, and an abraded metallic coating on the substrate, wherein the abraded metallic coating has a substantially uniform patterned appearance which simulates the surface appearance of polished stainless steel. A top coating, which may be a relatively thick PVC coating or a thin coating of polyester, epoxy, or acrylic, may overlie the abraded metallic coating on an obverse side of the substrate. The metallic coating may be a Zinc-Nickel alloy and a pre-treatment coating may be applied beneath the top coating. A primer coating may be applied beneath the PVC top coating.
