The Fabrication And Performance Of High Temperature Carbon-Carbon Composites Containing Tantalum Filler

In this study, a fabrication process for manufacturing carbon-carbon (C/C) composite is used to make ultra-high temperature resistant material. Tantalum filler powders are embedded in the composites during the material densification using liquid resin re-infiltration techniques. The C/C ablation performances and oxidation rates are investigated after exposure to an oxyacetylene flame and high temperature air oven respectively. SEM is used to characterise the C/C before and after high temperature testing. The mass and liner ablation rate for tantalum-impregnated C/C was found to be superior to the as-prepared C/C composite materials.
