Dynamic-Mechanical Analysis Laboratory
In DMA laboratory moduli and damping of polymeric materials (both depending on the viscoelastic properties) are studied. DMTA measurements can be performed in isothermal as well as non-isothermal conditions and under cyclic stress while a certified frequency is applied. The test is carried out in different modes including single cantilever bending, dual cantilever bending, 3point bending, tension, shear and compression. The changes in the storage and loss moduli and damping factor (tan δ) are measured as a function of time, frequency or temperature.
