Discontinuous Graphite Fiber Reinforced Al 520 Matrix Composite for Structural Reactive Material

Discontinuous graphite fiber reinforced aluminum magnesium matrix composite with microscopically dispersed add-on oxidizer coating is proposed for the application of enhanced lethality munitions. The composite with the coating is light-weight and reactive, which will generate high reaction temperature and a large amount of reaction heat. The composite also has sufficient mechanical strength for many structural applications. And more importantly, the dynamic behaviors of the composite are inline with the requirements and applications of reactive materials. Upon impact, the composite is fractured into small fragments due to the presence of graphite fibers. These small fragments can react easily and quickly. During Phase I, MMCC will team up with University of California, San Diego to study the constitutive behavior of this composite.
