GLASS FIBRE STRUCTURE FOR REINFORCING AGGLOMERATED ABRASIVE OBJECTS

摘要

The invention relates to a glass fibre structure coated with a resin composition for reinforcing agglomerated abrasive objects, the resin composition being characterised in that it comprises the indicated amounts of the following constituents, the amounts being expressed in weight percentage of solid materials: between 75 and 98 % of a mixture of at least one novolak having a glass transition temperature which is less than or equal to 60 % and at least one novolak having a glass transition temperature higher than 60 °C; between 0.5 and 10 % of at least one wax; and between 0 and 3.5 % of at least one plasticising agent. The invention also relates to the resin composition suitable for producing the reinforcing structure and the agglomerated abrasive objects incorporating such a structure, especially abrasive grinding wheels.
