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 become 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. 25 refs., 13 figs., 1 tab
