| dc.description.abstract | This thesis presents an analysis of Equal Channel Angular Extrusion (ECAE) of polymers, a unique process that controls the state of strain and molecular network orientation during a solid state extrusion. The goal of this research is to test the feasibility of the ECAE process by: a) designing and building a system to extrude thermoplastic sheets, b) numerically predicting the stress and strain distribution in the process, and c) testing and comparing the extruded product with the expected results. The test methods performed are the use of the optical polariscope to measure the birefringe angles and the use of ultrasonic testing of materials to measure elastic moduli. Extrusion variables that affect the extrusion process, such as extrusion temperature and extrusion rate, are investigated in order to determine extrusion process controls. | en |
