Summary The development of the stress intensification factor ( K IC ) and the fracture strength (σF) have been determined for a range of composite products. Changes in K IC resulting from storage are equated to the progression of polymerization and the loss or gain of plasticizer. The inherent flaw size, relating toughness to strength, varies in a manner which is more consistent with a matrix dependence than upon any quantifiable filler parameter.
