Abstract

High strength reinforcing fibres, (I) having length >=10 mm and modulus of elasticity >=1 x 104 kp/mm2, are incorporated in abrasive discs contg. abrasive grains, resin-esp. thermosetting resin binder and filler. The fibre reinforcement may consist of mono-crystal whiskers and/or polycrystalline metal whiskers and/or B fibres, partic. synthetic, inorganic fibres. Fibre adhesion in binder matrix is improved by providing the fibres with a surface coating having a high chemical and/or physical affinity to binder, e.g. by oxidn. Thus, the fibres may be high-strength C fibres, oxidised on surface, or may consist of drawn metal wires, esp. of higher alloyed C steel coated with a primer. Working velocity can be increased without increasing vol. proportion of reinforcing material in abrasive disc.
