An increase of mechanical properties of thin-walled ceramic moulds for the investment casting technology has been the main purpose of the undertaken research work. Partial replacement of grain silica materials with aluminosilicate materials in the fibrous form is an essence of a new concept of structural change of the moulding material. There have been prepared materials of various fibre fraction contained in the matrix and their mechanical properties have been examined, namely their bending strength MORI, work of fracture FI, and the deflection_fmax. An addition of ceramic fibre to the material matrix results in the increase of all the mechanical properties. The fibre fraction ranging from 25 to 50 wt-% is optimal as far as mechanical properties and the spraying technology of building the thin-walled mould are concerned.
