Fatigue of Boron-Aluminum Composites.
Abstract
The mechanisms of fatigue failure in composites of boron-6061 aluminum under oscillating tensile loads were determined and a phenomenological model of fatigue failure is outlined. A linear relationship between fatigue limit and filament content is suggested as an interim criterion for the specification of minimum acceptable composite fatigue properties and for use in the design of structures. Unidirectional filament reinforcement was less effective under cyclic loads then under static loads, and the low-cycle resistance of the composites was sharply reduced when SiC-coated filaments were used as the reinforcements.
