Hollow‐fiber membranePolytetrafluoroethylene membranePorous structureStress‐strain curveStretching parametersPolytetrafluoroethylene (PTFE) porous hollow-fiber membranes were prepared by a method involving billet preform, paste extrusion, stretching, and sintering. The influence of stretching parameters including...
In addition to those properties, we also keep stress strain curves and we can also like measure like tensile modulus, which is also called like elastic modulus. We can also measure yield point. It's the point actually where the material starts, like yielding where actually from like a plasti...
In addition to those properties, we keep stress and strain curves and also measure tensile (elastic) modulus, yield point where the material starts yielding from the plastic to elastic region, and toughness in the area under the curve. In addition to those standard ASTM test methods, we also...

It is of great interest that no initial cyclic stress strain curve was observed under cyclic compression at peak holding time. This indicates that creep recovery due to anelastic relaxation decreases the ratcheting rate of PTFE material under compressive creep-fatigue conditions. This research provides...
