WASHINGTON, D.C., March 21, 2017 -- Polymers are used for myriad applications today, and perhaps the most important property that dictates which polymer is chosen for a given application is its "glass ...

Glass transition temperature (T g) is usually measured in relation to material stiffness, or modulus, and may also be known as the principal relaxation. The glass transition temperature of a thermoset ...

Polymer matrix composites (PMCs) exhibit impressive stiffness and strength properties that are commonly attributed to the reinforcing fibers. However, for many important mechanical properties, the ...

WASHINGTON, D.C., March 7, 2017 -- Glasses are not, perhaps surprisingly, technically solid in a crystalized form, but are substances frozen in a liquidlike structure. Many fundamental questions ...

The glass transition of polymer materials is a crucial factor that affects material properties. Typically, this transition is analyzed using Differential Scanning Calorimetry (DSC). However, sometimes ...

As anyone who extrudes plastic noodles knows, the glass transition temperature of a material is a bit misleading; polymers gradually transition between a glass and a liquid across a range of ...

Polystyrene has a glass transition temperature of about 100 C -- at room temperature it behaves like a solid material. But as its temperature approaches the glass transition temperature, polystyrene’s ...
