A composite structural laminate plate suitable for building maritime vessels or for building civil structures such as double hull oil tankers, bulk carriers, barges decks for roll-on roll-off ferries, orthotropic bridge decks or for building any structural application in which the traditional method of construction uses stiffened steel plates. The laminate has two facing metal layers that are structurally bonded to a polyurethane elastomer core which may have steel or rigid foam void sections embedded within. The laminate provides equivalent in plane and transverse stiffness and strength, reduces fatigue problems, minimizes stress concentrations, improves thermal and acoustical insulation, and provides vibration control. The laminate provides a structural system that acts as a crack arrest layer and that can join two dissimilar metals without welding or without setting up a galvanic cell. For applications like double hull oil tankers, the structural system provides an impact resistant structure that isolates the innermost hull skin from cracks, thereby preventing a loss of cargo such as oil into the environment, when accidental or groundings occur and the outer hull is pierced, penetrated, or ruptured.

An artificial foliage structure with wire cores embedded in its leafy parts causing these parts to “spring back” upon removal of compressive loading acting thereupon. These wire cores may be made of hard, springy steel such as piano wire or small diameter spring wire. Thicker, woody limbs and branches have embedded therein heavier wire cores that are sufficiently soft to be given a set solely by manually applied bending force.

A plain bearing is described having a bearing metal layer, supported by a support shell, made of an aluminum or copper alloy and having a lead-free running layer, possibly applied to the bearing metal layer over an intermediate layer, made of a zinc matrix having at least one further alloy element. To achieve good tribological properties, it is suggested that the zinc matrix of the running layer contains 1 to 49 wt.-% bismuth as an additional alloy element.

Methods of producing composite products formed between at least two different metal structures in a side-by-side configuration are provided. The method includes providing at least two structures made of different materials that are not compatible for welding or conventional cladding processes. A geometric profile is provided in at least one of the edges of the first structure, and a corresponding mirror image of the geometric profile is provided in a corresponding edge of the second structure. The two structures are positioned together so that the profiled edge or edges form a complimentary composite structure and are then solid-phase bonded to form a composite product. The process may be repeated with additional structure at either end of the first or second structure to achieve multiple side-by-side products. The methods and corresponding products provided herein yield edge to edge products suitable for various electrical connection type applications.
