Abstract
A laminate includes a metal substrate and a sliding layer overlying the metal substrate. The sliding layer can include a polymer fabric. The polymer fabric can include first polymer P1. The sliding layer can further included a melt-processable matrix polymer. The melt-processable matrix polymer can include a second polymer P2. In embodiments, either P1 or P2 is a fluoropolymer. The sliding layer can further include a filler. In embodiments, the total amount of fluoropolymer and filler in the sliding layer is at least 30 vol %.
