Abstract

Aluminum alloys are important light metals for weight reduction in cars and aircrafts. However, aluminum alloy applications are limited when the aluminum alloy strength is not sufficient. The mechanical properties of Al5052 can be improved by using carbon fiber reinforced aluminum composites fabricated using multiple-pass friction stir processing (FSP). The mechanical properties and microstructures of the composites are investigated with the composite having 18.9% higher tensile strength and 19.7% higher elongation rate than the matrix. The microstructure observation indicates that the carbon fibers are uniformly dispersed in the matrix. Fractography results show pulled-out carbon fibers in the inner surfaces of dimples. The strengthening of the composites is due to load transfer to the homogeneous carbon fibers.
