Abstract
A non-asbestos friction material is obtained by molding and curing a composition which includes a fibrous base other than asbestos, a binder and a filler wherein the fibrous base contains no inorganic fibers having a length of at least 5 μm, a diameter of up to 3 μm and an aspect ratio greater than 3, and the binder includes a resin having a flow of at most 27 mm at 125° C. The friction materials having a porosity of 8 to 20% exhibit a good braking performance and stability, are endowed with good resistance to fade and wear, provide enhanced safety and hygiene during production, and have minimal impact on the human body from dust generated during use.
