Abstract

Microstructure and mechanical properties of fibrous $A1_2O_3-(m-ZrO_2)/t-ZrO_2$ composite were investigated depending on the dimensional array. By the change of stacking arrangement of fibrous filaments, 2 and 3-dimensional fibrous composites were successfully obtained without bulk defects such as shrinkage cavity and cracks. The maximum mechanical properties were achieved In the 3-dimensional array composite, due to the fine fibrous and dense microstructure control, in which the values of vickers hardness, fracture toughness and bending strength were about 1507 Hv, $7.2MPa{\cdot}m^{1/2}$ and 650 MPa, respectively.
