As a continuation of our previous work, which concerned the relationship between curing degree and
key neat resin properties, an experimental study was carried out to evaluate the applicability and
limitations of the results of the characteristic neat resin properties on polymer matrix composites. The
glass transition temperature, storage modulus and fracture energy of a unidirectional carbon fiberreinforced epoxy laminate were studied as a function of the degree of cure. Using dynamic mechanical
and fracture mechanics tests a good correlation between the key neat resin and laminate properties was
established.
