Dynamic Mechanical Analysis (DMA)

dynamic mechanical testing DMA for advanced composite materials for stress, strain, temperature, time IMR Test Labs has some of the most experienced advanced composite materials (ACM) testing technicians and scientists in the industry.  Their extensive knowledge of Dynamic Mechanical Analysis (DMA) can help you make data-driven decisions on the production and utilization of your advanced composite materials, especially in aerospace applications. Our lab features a state-of-the-art TA Instruments Q800 Dynamic Mechanical Analyzer. The non-contact linear drive technology of the DMA provides precise control of stress, as well as air bearings for low friction support.  IMR has become a leader in testing, measuring and analyses of the mechanical properties of non-metallic materials as a function of time, temperature, and frequency.  Our customers appreciate our thorough, concise reporting, as well as having the ability to talk directly with our technicians to discuss your product's testing protocols and results.

IMR's extensive menu of Dynamic Mechanical Analysis testing includes glass transition (Tg) temperature and secondary transition measurements, orientation determinations caused by processing, cold crystallization testing, properties of filler effects in composites, creep testing, stress relaxation, transient, dynamic oscillatory, stress/strain, phase difference and material stiffness testing. 

If your materials have to perform under extreme temperature conditions, the IMR DMA team is adept at determininig the viscoelastic properties of your samples as they are deformed under a controlled stress or strain. Our lab technicians can utilize the Q800 Dynamic Mechanical Analyzer to test samples between a temperature range of -150 to 600 ⁰C, a force range of 0.0001 to 18 N, and a frequency range of 0.01 to 200 Hz.
