In this work, the application of model used to predict the variation of dynamicalmechanical  properties (E’ and E’’) as a function of temperature was analyzed. Vinylesterand polyester matrices were used. Composites with unidirectional and mat glassfibres were prepared by hand lay-up. .The Weibull modules (m) were lower forpolyester than for vinyl-ester indicating that the first one has a more crosslinkedstructure and exhibit a narrower glass transition. For vinyl-ester, activation energy washigher for composites than for matrix.
