    Abstract

    The characterization of graphite/metal tubing will be discussed. Both destructive and nondestructive testing will be addressed. Test procedures to be discussed will include nondestructive (ultrasonic) modulus determination, longitudinal tension testing, short column compression testing, the hydrostatic burst (transverse) test, and thin-wall tube torsion test. The test fixtures and techniques used for these tests will be described, and typical test results for pultruded graphite/metal tubing will be presented. The use of these procedures to determine four of the five elastic constants and failure strengths necessary to characterize a transversely isotropic material in plane stress laminate analysis will be also discussed. Directions for future research in the testing area will be presented.
