Research into the elasticity and dumping factors of the polymer composites reinforced with glass, carbon and aramid fibers

Main theological parameters of the laminar polymer composites reinforced with glass, carbon and aramicle fibers were investigated by the author in an experimental way. The methods of analyse of free torsional vibrations of the composite elements were applied. The results were as follows:

– comparison of the rheological properties (elasticity and dumping factors) between tested composites

– comparison between manufacturers catalogue data on the shear modulus G and the results of experiment

– aproximation of the relation between shear modulus G and elasticity modulus E.
