6 FAQs about [Determination of storage modulus of silicone rubber]
What is the storage modulus E′ of silicone rubber?
As shown in the figure, the value of the storage modulus E′ of the silicone rubber specimen varies from 0.13 to 24.59 MPa with temperature and frequency. The variation law of the storage modulus E′ of the material with temperature and frequency is consistent with the results of Sawai , Placet , and others.
How do you measure the properties of silicone rubber?
These properties can be evaluated through measurement of the glass transition and melting temperatures using thermal analysis, in addition to the crystallinity and elastic modulus. This report introduces DSC and DMA measurements of silicone rubbers that were slow- and quench-cooled from room temperature to -150 °C.
How does test frequency affect the storage modulus of silicone rubber?
In general, for viscoelastic solid materials, the storage modulus E′ increases with the increase of test frequency . As the test frequency increases, the molecular chain segment motion of the silicone rubber specimen lags behind the change in external force and the internal consumption decreases.
Do dynamic viscoelastic properties of silicone rubber have a temperature-frequency dependence?
5. Conclusions In this work, the dynamic mechanical thermal analyzer was used to test the frequency spectrum scan of silicone rubber material in the range of different temperatures (−35 °C to 60 °C) levels, and the test showed that the dynamic viscoelastic properties of silicone rubber have obvious temperature–frequency dependence.
How can mechanical properties of silicone rubber be regulated?
The mechanical properties of silicone rubbers can be regulated by designing the cross-link density and cross-linking structure, and altering the molar contents of vinyl in the side groups of methyl vinyl silicone rubber (MVQ) leads to different cross-linking structures and cross-linking densities in the vulcanized rubber.
Does temperature affect the mechanical properties of silicone rubber?
Many constitutive models have been proposed to display the complicated behavior of silicone rubber, which includes hyperelasticity , viscoelasticity , and visco-hyperelastic behavior . It was found that the mechanical properties of rubber are affected by temperature and time.
