Fabrication of Graphite-Aluminum Composites via Pultrusion.

Abstract

The objective of this program was to establish the feasibility of producing sound rectangular bars by the pultrusion process. Previous work conducted under contract DAAG-46-76-C-0068 identified process problems for non-round sections. Addressed in the present work were: (a) Elimination of rectangular bar twisting during pultrusion; (b) Surface improvement by application of thin aluminum claddings; (c) Incorporation of thin titanium interleaf to the composite; (d) Further evaluations of composite heatreatability without cracking. Rectangular bars of improved geometric uniformity, clad with aluminum and optionally interleafed with titanium were successfully fabricated by pultrusion processing. Twelve bars were delivered to AMMRC for evaluation. It was concluded that the pultrusion technology developed thus far has potential for the future fabrication of clad and/or interleafed, uniaxially graphite fiber reinforced aluminum-matrix, composite structural members.
