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 ...

Sample preparation: A flat disc of about 10 mg weight was cut out from the basic material and cooled from room temperature to -100 °C at 5 K/min DSC measurement: Heating was carried out from -100 °C ...

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 ...
