The present invention relates to ceramic matrix composites containing ceramic fibers, improved fracture toughness and others for industrial and aerospace applications requiring low thermal weight and excellent thermal and mechanical properties. Of composite materials with the following characteristics: Silicon carbide and chemical composition M n + 1 AX n (M is a transition metal selected from Ti, V, Cr, Sc, Zr, Nb, Mo, Hf or Ta; A is Al, Si, P, In a ceramic matrix comprising a MAX phase compound having a group A element selected from S, Ga, Ge, As, Cd, In, Sn, Tl or Pb; X is C or N; n is an integer from 1 to 3) A composite material containing continuous silicon carbide fibers, impregnating a porous fiber preform containing silicon carbide fibers with a slurry containing silicon carbide particles and MAX phase precursor 102 and then impregnating a melt containing silicon. A ceramic matrix composite material manufactured to 104. [Selection] Figure 1 |
