abstract = "Polytetrafluoroethylene (PTFE) is semi-crystalline in nature with its linear chains forming complicated temperature and pressure dependent phases. Experimental studies on pressure-induced phase transitions using shock-loading techniques and the resulting changes in crystalline structure are presented. Disks of pedigreed PTFE 7C have been shock loaded in momentum trapped assemblies using a 80 mm gas launcher, and recovered in a density graded polymer network. Experiments were performed with impact pressures from 0.4 to 0.85 G Pa to investigate the material response above and below the phase II to phase III crystalline transition. Recovered samples were planar with residual strains of 1.3\%. Changes in crystalline structure of the recovered materials were quantified using dynamic scanning calorimetry (DSC) and density.",
