An elastomeric laminate comprises at least two adjacent cohesive layers, the first layer consisting of a composition based on 10 to 100 phr of a copolymer of ethylene and of a 1,3-diene of formula CH.sub.2═CR—CH═CH.sub.2, the ethylene units in the copolymer representing more than 50 mol % of the monomer units of the copolymer, the symbol R representing a hydrocarbon chain having 3 to 20 carbon atoms, from 0 to 90 phr of a diene elastomer having a content by weight of diene unit of greater than 50%, and a crosslinking system; the second layer consisting of a composition based on a diene elastomer having a content by weight of diene unit of greater than 50% and a crosslinking system. Also disclosed is a tire, in particular a tire provided with a sidewall, comprising this composition.

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

A piston for a heavy duty diesel engine including a composite layer forming at least a portion of a combustion surface is provided. The composite layer has a thickness greater than 500 microns and includes a mixture of components typically used to form brake pads, such as a thermoset resin, an insulating component, strengthening fibers, and an impact toughening additive. According to one example, the thermoset resin is a phenolic resin, the insulating component is a ceramic, the strengthening fibers are graphite, and the impact toughening additive is an aramid pulp of fibrillated chopped synthetic fibers. The composite layer also has a thermal conductivity of 0.8 to 5 W/m.Math.K. The body portion of the piston can include an undercut scroll thread to improve mechanical locking of the composite layer. The piston can also include a ceramic insert between the body portion and the composite layer.

A module mat system with first layer that is joined to a second layer by fusion welding, hot welding, hand welding, seam welding, heat pressing, or other methods know to those having skill in the art. Each layer has a central core with a first cellular structure formed from ribs extending from the interior surface. The cross section of the ribs in the central core of the first layer matches the cross section of the ribs in the central core of the second layer such that when fusion welded together the ribs of the central core of the first layer weld to the ribs of the central core of the second layer.
