Web4.4 Glass transition temperature All polymers will undergo a transition from a glassy to a rubbery state at some temperature. This temperature is the glass transition temperature ( Tg). It coincides with segmental motion of the polymer chains and a 4–5 order of magnitude reduction in modulus. WebApr 30, 2024 · For glass-fibre reinforced PEEK, this crystallisation phenomenon also occurs and happens earlier. Indeed, during tribological tests, the friction coefficient is higher than in the case of pure PEEK. The heat dissipated in the material is, therefore, higher. The glass transition temperature is then probably reached earlier.

Glass Transition Temperature (Tg) of Plastics

WebAug 4, 2024 · The glass transition temperature is the point where the print will begin to undergo internal stress due to thermal contraction. The farther Tg is from room temperature, the more the plastic will shrink. Shrinkage causes the print to warp off of the bed and the layers to split apart from each other.
