Abstract
A friction material characterized by using a resin composition for friction materials, the resin composition containing, as a binder, an aromatic imide oligomer having an addition-reactive group at an end thereof. Also described is a resin composition for friction materials, containing: a powder of an aromatic imide oligomer having an addition-reactive group at an end thereof; at least one type of fiber selected from the group consisting of carbon fiber, aramid fiber, glass fiber, ceramic fiber, and metal fiber; and an inorganic filler. The friction material and a resin composition for friction materials have good formability and in which the binder itself has excellent heat resistance and mechanical properties, compared to a friction material using a phenolic resin as a binder.
