The objective of this program was to develop a graphite/aluminum com posite using epoxy to form an interfacial bond between the fibers and the aluminum. Twenty-two test panels were fabricated and tested for tensile strength and tensile elastic modulus, both in the longitudinal and transverse directions. Although problems were encountered in gripping the longitu dinal tensile samples, strengths of 1490 MPa (216 ksi) and 89.6 MPa (13 ksi) were achieved in the longitudinal and transverse directions, respectively.
