Metravib DMA+1000/2000

The capabilities of the new Metravib DMA+ 1000/2000 truly break new ground in field of Dynamic Mechanical Analysis. The frequency range of the system extends from 10-5 to 1000 Hz and the force range is +/-1000 N. The addition of the Multitest software adds the capability to do fatigue testing. The addition of the microscope adds the capability to do crack grow testing. And, the addition of the HFC 200 adds the ability to do coupled calorimetry. Edu Ruiz, et al of Ecole Polytech in Montreal recently used this technique to simultaneously measure modulus, cure, and shrinkage on pre-pregs and thermoset resins. Of course, all of this is in addition to the standard DMA geometries; three point bend, single & dual cantilever, planer shear, film shear, tension and compression, etc.
