To provide a friction material which can show excellent braking effectiveness and does not produce any foreign sound even when its surface is wetted with water upon e.g. automobile washing and is a friction material not suffering from difficulties in prior art and containing potassium titanate fibers excellent in fading resistance.
This material comprises a fiber component, a binder component and a filler component. The fiber component at least partially consists of potassium titanate fibers having a fiber length of 1μm to 1mm and a fiber diameter of 0.2μm to 50μm and nonfibrilated aramid fibers having a fiber length of 0.5-1mm and a fiber diameter of 1-20μm or at least partially consists of potassium titanate fibers having a fiber length of 1μm to 1mm and a fiber diameter of 0.2-50μm and fibrilated aramid fibers having a fiber length of 0.5-6mm and a fiber diameter of 1-20μm.
