Differential scanning calorimetry (DSC)

Using differential scanning calorimetry (DSC) the glass transition is detected as a shift in the heatflow versus temperature curve. With most DSCs software is used to identify this shift. For composites, the shift is sometimes difficult to detect because of the small amount of resin present in a fibre reinforced material. Also if the crosslink density is high, the transition maybe difficult to detect because the heat capacity change is small.
