Abstract: 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.

Abstract: The teachings herein relate to tubes formed of a composite material and improved methods for forming the tubes. The composite material includes metallic layers and a core layer interposed between the metallic layers. The core layer preferably reduce the transmission of sound and or heat between the two metallic layers.

Abstract: A laminate structure and method of welding the laminate structure 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 made of an adhesive material also described as a viscoelastic adhesive material. 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. The adhesive core includes a plurality of electrically conductive filler particles dispersed in the adhesive materials. The filler particles are made of a first filler material and at least a second filler material which is a different material than the first filler material.
