Dynamic Mechanical Analysis (DMA)

Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. Our DMA instrument operates over a wide temperature range (-150 to 600°C) and provides multiple modes of deformation including dual/single cantilever, tension, and torsion. Other fixtures and deformation modes may be available on request.

Applications:

Determination of Tg of highly crosslinked or crystalline materials and composites

Determination of modulus under a variety of conditions

Creep Experiments

Projection of material behavior using Time-Temperature-Superposition Experiments

Material Selection

Determination of curing behavior

Film/Fiber Stress-Strain Measurements

Work We've Done

Glass Transition Temperature

A client needed us to measure the glass transition temperatures of a series of cross linked networks along with any subambient β-transitions that would prove important to their application. We ran a temperature sweep at a constant strain and frequency to measure the two transitions. We were able to assist them in choosing the best material for the application based on the material properties and the application.

In another case, where a client needed data at higher frequencies than mechanically obtainable by DMA a time temperature superpositioning (tTS) study was done to predict the material response at those frequencies.
