Estimating the term…
A wet friction material and its manufacturing method are provided. The wet friction material has a substrate having a surface and a very superficial layer. The very superficial layer is provided on the surface of the substrate and contains resin and fibers. The resin and the fibers are heated by one of a laser beam, a heating plate and a heating roller so as to thermally change the very superficial layer in a short period of time. Such manufacturing method is capable of evenly carbonizing the resin and the fibers of the very superficial layer of a friction surface of the wet friction material so as to flexibly deal with a variety of size of products.
A wet friction material comprising:
A manufacturing method of a wet friction material comprising the step of heating resin and fibers contained in a very superficial layer provided on a surface of a substrate by one of a laser beam, a heating plate and a heating roller so as to thermally change the very superficial layer in a short period of time.
