Properly designed discontinuously-reinforced MMCs have been projected by linear-elastic fracture mechanics to be competitive, on both cost and performance bases, with cross-plied graphite-reinforced polymer-matrix composites and continuously-reinforced MMCs. With respect to the latter, discontinuously-reinforced MMCs achieve considerable advantages in virtue of their lower-cost reinforcements and their fabricability by standard metal-working practices. Discontinuously reinforced MMC billets can also be produced through powder-blending and direct-spraying techniques. SiC short fibers, whiskers, and particulates are typical of the discontinuous reinforcements used in 2124 and 6061 aluminum matrices. 18 references.
