This work deals with mechanical properties of thin-walled ceramic moulds for investment casting at the dewaxing stage. The main purpose of this work has been increasing their bending strength, expressed by the modulus of rupture (MOR), and determining their corresponding work of fracture, characterised by the fracture index (FI). An essence of the concept is applying aluminosilicate materials in the fibrous form along with grain silica materials as the reinforcing material for the thin-walled mould matrix.
