Abstract:

A fatigue test of one grade of pyrolytic graphite at room temperature is described, and the resulting preliminary S-N curve is presented. This is the first such data obtained as far as is known. Also described is a test of pyrolytic graphite hemispheres in the Janus Arc Tunnel, a unique facility which can simulate closely glide re-entry heating. The thermodynamic capability of both the tunnel and the material was thereby demonstrated.
