Resin Molding and Rheology, 22nd Session: "Measurement of the Elastic and Viscous Components of Resin"
In the resin molding process, liquid testing measurements are common! Introducing the behavior of pure elastomers and pure viscous materials.
Resins possess both elastic and viscous components, and in this column, we will explain the measurement methods for this property. Dynamic viscoelastic devices apply a steady-state sinusoidal strain to the specimen and measure the response stress, investigating the behavior of the viscoelastic material from the phase difference between the two. For solid testing, both ends of the sample are fixed, and a longitudinal sinusoidal wave is applied. When the sample is in liquid form, such measurements cannot be performed in this manner, so the sample is placed in a container and a sinusoidal wave in the rotational direction is applied. Since the molding process of resins includes a molten state, measurements for liquid testing are common.
