Dynamic viscoelastic measurement of polyurethane rubber.

It is also possible to create master curves in tensile, shear, and bending modes other than compression mode!

We would like to introduce the quality technology of AITES Co., Ltd., specifically regarding the dynamic viscoelasticity measurement of polyurethane rubber. DMA is an analysis that applies periodic vibrational loads to polymer materials and measures elasticity and viscosity as a function of temperature from the resulting stress and phase difference. In this instance, we conducted measurements using cylindrical rubber samples in compression mode. The measurement results indicate that the glass transition temperature is -15.7°C, as shown by the temperature dispersion curve of Tan δ, and we created a master curve based on the time-temperature superposition principle. Please feel free to consult us when needed. 【Methods of Applying Load】 ■ Tension ■ Compression ■ Bending with both ends supported ■ Free-supported three-point bending ■ Shear (sliding) *For more details, please refer to the PDF document or feel free to contact us.

Dynamic viscoelasticity measurement of CFRP

We present the results of DMA measurements conducted on CFRP made of plain-woven carbon fiber with an epoxy resin matrix!

We would like to introduce the dynamic viscoelastic measurement of CFRP conducted by our company using the bending mode. When performing dynamic viscoelastic measurements using DMA, CFRP is generally highly elastic, and it is considered that measurements using the bending mode are suitable due to its applications. The deformation modes of DMA can measure in any mode as long as the size requirements are met, but it is ideal to select appropriate conditions based on the material's shape, elastic modulus, and the purpose of the measurement. If you have a subject for which you would like to measure dynamic viscoelasticity, please feel free to consult us. 【Measurement Modes】 ■ Tensile ■ Compression ■ Bending (two-point/one-point/three-point) ■ Shear *For more details, please download the PDF or feel free to contact us.
