High Temperature Compression Testing Of An Advanced Carbon-Carbon Composite In An Oxidizing Atmosphere, Joshua C. Walls

Electronic Theses and Dissertations

Compression testing of an advanced, three-dimensional weave, carbon-carbon composite was performed from room temperature to 2192°F (1200°C) in an oxidizing environment. The material tested is primarily used for missile nose cones and rocket nozzles. A test system and test method was developed for performing high temperature compression testing and techniques were developed for machining the material to minimize fiber damage and maintain accurate tolerances. Test specimens were cut from a block of the test material in the three principal fiber orientations, and off-axis tests were cut at 45" orientations to each principal fiber direction. The specimens were tested by direct …
