Shrinkage restraint forces in oriented PET, PMMA and PET/PMMA blend: Contrasting effects on cooling

Shrinkage restraint forces in oriented PET, PMMA and PET/PMMA blend: Contrasting effects on cooling

We have performed shrinkage restraint force measurements on three shape memory polymers of polyethylene terephthalate (PET), polymethyl methacrylate (PMMA) and a blend of the two at a range of temperatures. Observations are made of the change in stress during temperature rise, hold and cooling. All...
