abstract Measurements of the dynamical properties are universal method of investigations of the materials behavior exposed to the dynamic sinusoidal variable forces. In the paper the results of the tests of dynamic properties of PA/PP blend and its fiber glass composite have been presented. The blend of 50% PA and 50% PP with 2% of compatibilizer by weight and the composite of that blend with fiber glass were produced on the industrial production line in Polimarky, Rzeszów. The tests were performed by the DMTA method. Tested specimens were bended of the frequency 1 Hz in a temperature range from 173 to 473 K and with a heating rate 2 K/min. In the paper the run of changes of the storage modulus and the loss tangent versus temperature for PA/PP blend and its fiber glass composite has been presented. Key words: blend, composite, dynamic properties, DMTA
