Synopsis : Advanced carbon-carbon composites for spaceplane application have been developed which have high mechanical properties and good oxidation resistant coating. The C/C composites are reinforced with two-dimensional carbon fiber fabrics and coated with multiple SiC layers by chemical vapor deposition. After the evaluation of the mechanical properties, the C/C composites have been exposed to an oxidative atmosphere in a temperature range between 500 and 1700. The C/C composites have exhibited a tensile strength of 323 MPa, tensile modulus of 132 GPa, flexural strength of 417 MPa, flexural modulus of 119 GPa, compressive strength of 264 MPa, and compressive modulus of 129 GPa. The multilayer coating has been found capable of protecting the C/C composite against air oxidation up to 1700. |
