Composite multilayer material

摘要

A composite multilayer material is described which exhibits relatively high wear and delamination resistance without impairment of the coefficient of friction in the presence of oil. The composite multilayer material contains at least one powder-form polyaramid in its overlay, the content of PTFE or of PTFE together with the other fluorothermoplastics which form the matrix material amounting to 55-90 vol. %, the content of further fillers amounting to 9.5-44.5 vol. % and the content of polyaramid amounting to 0.5-10 vol. %.
