  • This paper aims to observe the micro-mechanical behaviour of tow geometry during deformation of dry woven carbon-fiber fabric. With the increment of shear angle fabric experiences 'lock-up'phenomenon. In this paper, deformation of micro-mechanical parameters such as tow interval, change in tow amplitude and wavelength are investigated. To observe the micro-deformation of the fabric structure, appropriate specimens from bias extension and biaxial tests are sectioned and observed under the microscope. It was found that different loading conditions cause geometric deferences in the tow architecture.
