Abstract
Abstract A slide bearing laminate and method for producing the same, wherein a low-friction composite facing or layer is secured to a carrier or foundation strip by a bonding procedure. The composite facing comprises textile material having a low-friction component on one side and a glueable component on the other side, which latter is bonded to the carrier strip. The adhesive or bonding agent preferably occupies the interstices of the composite facing, and is especially formulated to resist failure by being mixed not only with friction and heat-conducting filler elements but also with fibrous fillers which particularly contribute to the failure resistance.
