Summary

Numerous theories have been developed over the last three decades for explaining the toughening behavior of discontinuous fiber-reinforced brittle matrix composites. The issue is the practical engineering utility of these theories. Upon compiling a table of fiber parameters that are identified in the predominant toughening mechanisms, a number of important features becomes evident for achieving high toughnesses. First, all of the mechanisms indicate that a high-fiber volume fraction is desirable. Second, residual stresses appear to influence all of the composite-toughening mechanisms. Third, the highest fiber tensile strength is preferred. Finally, fiber diameter and fiber-matrix interfacial shear strength are also important, but both are composite system- and toughening mechanism-specific.
