Tensile clamps are designed for uniaxial deformation of films and fibers. The sample chamber mounts directly to the DMA. The motor can deliver reproducible forces over a wide range and the force can be changed rapidly, enabling a broad spectrum of material properties to be measured. The Online Industrial Exhibition. This mode is ideal for soft materials such as gels, pressure sensitive adhesives, and high viscosity resins. This mode can also be used to make measurements of expansion or contraction, and tack testing for adhesives. This field-proven design provides for efficient and precise temperature control over the entire temperature range in heating, cooling, and isothermal operation.
This enables the system to capture a broad spectrum of material properties with the highest level of sensitivity and accuracy. This new capability unlocks complete material characterization under virtually any set of test conditions. Faster electronics, all new digital signal processor DSP controls, and an enhanced drive system allow for an all-new type of strain control in the DMA The result is the most stable platform for mechanical characterization of materials even under extreme conditions.
As the relative humidity is increased The DMA is the only commercial Dilm instrument to feature a temperature-controlled force and displacement transducer, providing unparalleled measurement stability and accuracy. Temperature-Controlled Transducer The transducer is temperature-controlled to eliminate drift associated with temperature changes from the sample or laboratory environment.
In oscillation experiments, the instruments use a variety of methods for applying a static load to prevent buckling and unnecessary creep. Dual cantilever is especially ideal for measuring the cure of supported thermosets. Tensile folm are designed for uniaxial deformation of films and fibers.
Tension Tensile clamps are designed for uniaxial deformation of films and fibers. Compression is suitable for low to moderate modulus materials e. Visual guides aid in aligning film samples and integrated supports simplify fiber testing. Parallel plate compression measurements are most suitable for low to moderate modulus materials such as foams and elastomers.
A new self-aligning mechanism ensures etnsion parallelism of upper and lower plates, enhancing strain and force uniformity while simplifying user interaction and improving modulus accuracy and precision. This comprehensive set of information is invaluable for method development, procedure deployment and data validation.
The new DMA Express interface is designed specifically for new users and those with simple, well-defined experimental requirements it presents test setup details in easy-to-choose, self-contained forms. Second, tensile test devices work primarily outside Open the catalog to page The advanced data collection system automatically saves all relevant signals, active calibrations, and system settings.
In many applications, the inelastic, or viscous component, is critical. The GCA uses cold nitrogen gas generated from controlled evaporation of liquid nitrogen. Go beyond conventional DMA testing and program experiments that mimic complex real-world conditions through an unlimited combination of 23 available steps.
Film Tension Clamp Calibration
The standard compression kit includes parallel plates of 15 mm and 40 mm diameter, ideally designed for bulk measurements of moderate to low stiffness samples. The motor can deliver reproducible forces over a wide range and the force can be changed rapidly, enabling a broad spectrum of material properties to be measured.
Open the catalog to page 8. View brochure Contact Us. DMA differs from other mechanical testing devices in two important ways. The critical drive components of the DMA are mounted within a high-stiffness aluminum casting that is rigidly mounted to an FEA-optimized instrument frame.
For routine use and common test types, DMA Express shortens training time, reduces the possibility for mistakes in experimental design, and inspires confidence. This mode is ideal for soft materials such as gels, pressure sensitive adhesives, and high viscosity resins. A comprehensive set of relevant tools are available for real-time data analysis, even during experiments.
Available in sample lengths of 8 mm, 20 mm, and 35 mm, the cantilever clamps can be used in single or dual configurations. First, typical tensile test devices focus only on the elastic component.
It is designed for use with the Q Dynamic Mechanical Analyzer. Open the catalog to page 5. In oscillation experiments, the instrument uses constant and variable methods to apply a static load that prevents buckling and unnecessary creep. This mode can also be used to make measurements of expansion or contraction, and tack testing for adhesives.
Shear Sandwich Two equal-size pieces of the same material are sheared between a fixed and moving plate for the measurement of shear modulus, G. Systems without this design feature suffer from poorly controlled deformation in unsupported designs, or diminished sensitivity where spring guidance is employed. The transition temperatures of loose powders can be difficult to measure by mechanical techniques. With this new capability, the DMA can perform a complete material characterization protocol under a diverse test conditions in a single experiment, or apply mechanical conditioning immediately followed by characterization.
The penetration kit is designed for higher stiffness materials and local measurements through the use of smaller probes: The slide is guided by eight porous carbon air bearings. The DMA offers your choice of two dedicated environmental systems: Compression In this mode, the sample is placed on a fixed flat surface and an oscillating plate applies force. It can also be used to measure expansion or contraction, tack testing for adhesives, compression set of rubber o-rings, and much more.
It utilizes state-of-the-art, non-contact, linear drive technology to provide precise control of stress, and air bearings for low friction support. Q Technology Drive Motor Optical Encoder The Q uses a non-contact, direct drive motor to provide the oscillatory or static force required.
DMA – TA Instruments
The powder accessory for the DMA is used with the dual cantilever clamp to observe transition da of loose powdered materials by DMA, combining the enhanced sensitivity of mechanical analysis with the simple sample preparation of powder characterization techniques.
The motor is constructed of high performance composites that ensure low compliance and is thermostated to eliminate heat build-up even when using large oscillation amplitudes and high deformation forces.
Only TA offers clamps that are ready to use out of the box without complex assembly procedures inherent to competitive designs. Stable, responsive peltier elements precisely control sample temperature while calibrated digital mass flow controllers deliver pre-heated gas of the prescribed ratio to achieve the target humidity. PEM properties can significantly change as functions of time and exposure to elevated temperatures and humidity, as water is the primary by-product of the electrochemical reaction of the fuel cell.
