In view to produce  near-net shapes of  ultra-high temperature ceramics  with complex geometries, ZrB2-SiC composite  laminates were produced by tape casting process using an aqueous system with acrylic latex emulsion as binder and plasticizer.  The co-dispersion of ZrB2 and SiC slurries in aqueous media was studied and characterized in terms of zeta potential and rheological measurements. A well-stabilized suspension with high solid concentration (up to 49 vol%) was prepared with 1.0 wt% of polyethyleneimine as dispersant.  Crack-free and flexible green tapes with a maximum thickness of approximately 600 µm were obtained with a binder content of as low as 3.0 wt% in relation to ceramic powder. The green tapes were then used to produce multilayer samples with different shapes and  composition gradient. Laminates were submitted to burn out at 500 °C in inert atmosphere and pressureless sintering at 2000 °C/2h in argon atmosphere.  Laminates were characterized by density, microstructure, mechanical properties and crystalline phases. Ablation performance was tested by supersonic plasma wind tunnel under different heat fluxes and compared with the same composition monolithic samples. The tests were performed at low pressure in reactive air plasma using a DC non-transferred arc plasma torch with heat fluxes of 0.52 MW/m2 to 2.2 MW/m2.
