The investigation of properties of investment casting moulds reinforced with ceramic fibre

Increasing of strength and permeability of the thin-walled investment casting ceramic moulds was the main goal of this work. Its essence is a new concept of the mould reinforcement, i.e. the full or the significant replacement of grain silica materials by fibrous aluminosilicate materials. An addition of ceramic fibre increase the permeability and green strength value of the ceramic shell mould material which allows for safe burning out of the pattern set.
