Abstract
An epoxide resin moulding composition, comprising PA1 (a) a phenol or cresol novolak epoxide resin, PA1 (b) dicyandiamide as a hardener, PA1 (c) an accelerator suitable for hardening with dicyandiamide, PA1 (d) 20 to 70% by weight of calcium carbonate and PA1 (e) 10 to 60% by weight of glass fibres, the quantity of components (d) and (e) together not exceeding 80% by weight, relative to the total weight of the epoxide resin moulding composition, is suitable with advantage for the manufacture of commutators and slipring bodies.
