Abstract
Fiber crimp behavior is an important parameter for processing performance and product quality. This study quantifies the mechanical behavior of a fiber during crimp removal. Single fiber tensile tests are performed on various fibers using a Textechno Favimat. Simultaneously, crimp removal is optically monitored. A methodology is developed to identify the true crimp removal region of the fiber load-extension curve during a tensile test. A mechanical model accounting for the nonlinear load-deflection behavior during crimp removal is also developed.
