Abstract
AbstractIn the present study, the effect of atomic oxygen (AO) exposure, as a simulation of low earth orbit, on the flexural properties and prefailure damage mechanisms of a series of short glass fiber/mica/epoxy composites under three‐point bending were elucidated using acoustic emission (AE) techniques. The incorporation of mica in the composites was shown to increase the resistance to AO as measured by the weight loss, ashing rate, and reaction efficiency. Furthermore, as the mica content increased, the resistance increased such that the all‐mica composite had over one order of magnitude lower ashing rate and reaction efficiency than did the all‐glass‐fiber composite. This increased resistance was caused by the mica particles preferentially orienting parallel to the surface of the composites, creating an inorganic barrier to attack. The AO‐induced erosion was found to have an insignificant effect on both the flexural properties and prefailure damage mechanisms because the erosion was confined to the epoxy surface only and did not affect the bulk.
