From Marshmallows to Space Shuttles You certainly know what a delicious gummy bear, a fluffy marshmallow, a high-performance tire and a rubber gasekt in a space shuttle have in common. These products are all the result of complex research processes. A successful introduction onto the market is always preceded by a great deal of testing to determine suitability in day-to-day applications. How are your products influenced by different temperatures, humidity levels, under pressure, under strain and under dynamic stress or a combination of these factors? The absolutely reliable and...

The NETZSCH Analyzing & Testing product range provides dynamic mechanical testing systems for a wide range of materials. Requirements for mechanical testing can be different. The development of highly sophisticated passenger tires requires information about dynamic material properties across a frequency range of over 100 kHz. Completely different requirements must be fulfilled by a truck tire. Here it is important, for example, to keep self-heating as low as possible and to achieve a long life time of the tire. The dynamic mechanical analysis with pulsed loads on the sample provides...

Modular Compatibility Dynamic Mechanical Analysis (DMA) The methods of dynamical mechanical (thermal) analysis (DMA, DMTA) are trendsetting technologies in the past and future in the field of material development and design. Dynamic mechanical analysis is an off-resonance method working with forced oscillations (see figure). First, a static load is applied to the test specimens. As a second step, a sinusoidal mechanical oscillation in a frequency range of 0.0001 Hz to 100 Hz is superimposed. In the case of pure elastic materials (e.g., perfectly elastic spring), the sample response to a...

Today, materials research and quality control today would not be complete without the technique of DMA - our DMA GABO EPLEXOR® systems. They are of absolute relevance and indispensable in determining the viscoelastic and thermal properties of materials with respect to the stimulating frequency, temperature, stress, strain and thermal history. The DMA GABO EPLEXOR® systems were developed to analyze synthetic materials (such as elastomers and polymers), reinforced plastics (CFRP and GFRP), metals, glass and ceramics, liquids, prepregs and paints, as well as even food and organic materials...

Application: Glass Transition of a Glass Fiber-Reinforced Polyamide The plot shows the temperature dependences of the storage modululs E’, and the mechanical damping factor, tanδ, of a 4 mmthick glass fiber-reinforced polyamide, PA66/GF, between room temperature and 140°C. The measurement was carried out in tensile mode, which requires a dynamic force amplitude of ±1000 N. This can be achieved by the floor-standing DMA GABO EPLEXOR® systems. With increasing temperature, E’ decreases continuously, whereas tanδ exhibits a maximum at approx. 75°C; this can be attributed to the glass transition...
