Abstract
The off-axis notched strength of a plain woven roving fabric CFRP laminate has been studied with emphasis on its fiber orientation dependence and dominant failure mode. Static tension tests were carried out on center hole specimens with different diameters of a hole and different fiber orientations, respectively. The off-axis notch sensitivity of the woven composite was elucidated on the basic of the experimental results obtained. The three-dimensional digital image correlation (DIC) method with two CCD cameras was used to measure full-field displacement filed and its variation during each tension test until rupture occurs. Local strain distribution, which was calculated on the displacement field measured by the 3D-DIC method, was used to identify dominant failure modes that are responsible for ultimate tensile failure in off-axis notched specimens of the woven CFRP laminate. To prediction of the off-axis notched strength of the woven CFRP laminate, applicability of the anisotropic notch size effect law that takes into account both the effects of fiber orientation and notch size was also discussed.
