1. A bearing laminate comprising:
a metal support layer, the metal support layer having a thickness of at least 0.1 mm and not greater than 2.0 mm;
a foam layer overlying the metal support layer, the foam layer including a polymeric foam having a density of at least 0.2 g/cm3 and not greater than 0.9 g/cm3, a thickness of at least 0.1 mm and not greater than 2.0 mm, a pore volume from 0.4 cm3/g to 10 cm3/g, and an average pore size from 20 microns to 300 microns;
a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix; and
an adhesive layer between the foam layer and the sliding layer, the adhesive layer including a pressure sensitive adhesive or a hot melt adhesive, and each of which comprising an acrylate-based adhesive, an epoxy adhesive, an ethylene-vinyl acetate copolymer, a polyether-polyamide copolymer, or any combination thereof, and
wherein the bearing laminate has a damping ratio of at least 10% and not greater than 50%.
