Novel Processing Apparatus to Control Multiscale Morphology in Ultra High Molecular Weight Polyethylene Fibers

Abstract

This work focuses on the use of a novel apparatus to study gel-spinning of ultra-high molecular weight polyethylene (UHMWPE). This device was designed to control the extensional flow and timescale of the spinning process through temperature, relative velocities, and gel composition. This work examines the effect of flow kinematics on the as spun fiber’s (ASF) properties. Flow kinematics are observed in situ using a laser micrometer to measure deformation of the fiber during spinning. Our results indicate that the maximum strain rate during spinning is the key processing parameter that determines the final crystalline properties of the ASF.
