| Abstract: | Plasticdeformation of uniaxially oriented polyethylene (PE) fiberhas been examined by small and wide angle synchrotron X-ray scattering.Morphology changes of the lamellar stack with deformation beyond yieldinghave been characterized and quantified. Atomistic simulations of tensiledeformation of the lamellar stack in the longitudinal direction comparefavorably to the experimentally observed morphological changes inthe PE fiber. Experimental deformations at 100 °C exhibit responsescomparable to those observed by simulation of deformation with constanttotal volume at 77 °C and a strain rate of 5 × 106s–1. Experimental deformations of the PE fiberat 25 °C were found to be comparable to simulated tensile deformationwith constant lateral dimensions at 77 °C and a strain rate of5 × 107s–1. Cavitation in the interlamellarregion was found experimentally in the PE fiber deforming at roomtemperature as predicted by simulation with constant lateral dimensionsat the higher strain rate. Melting, recrystallization, and removalof entanglements observed in the PE fiber deformation at 100 °Cagree with the simulation results of a constant volume deformationat the slower strain rate. The ability to define the deformation behaviorof PE at room and at high temperatures through simulation offers uniqueopportunities to examine how the interlamellar amorphous topologyaffects PE deformation.
