Development of Aluminum-Graphite Composite Shapes.
Abstract
The fabrication of composite panels and cylinders from commercially available aluminum-graphite composite wire was studied. Seven 3 x 3 x 0.1 inch panels of both uniaxial and cross-ply configurations were made and their mechanical properties were measured. Panels with aluminum-graphite faces, pure aluminum faces, and titanium faces were made. Two 12 x 12 x 0.05 inch titanium clad panels were submitted to AMMRC for evaluation. High strengths were achieved in uniaxial panels but degradation was observed in cross-ply panels. Metallographic studies showed that the degradation in cross-ply panels was probably due to fiber misalignment. Studies were conducted on two possible techniques for making cylindrical shapes. The wrapping of aluminum-graphite composite wire (1) around a mandrel, and (2) winding surface treated graphite yarn on a mandrel at room temperature under purified argon followed by vacuum impregnation with liquid aluminum. The work showed both techniques to be promising. (Modified author abstract)
