| Abstract: | Measurements of the residual stress distributions are beneficial to understanding the microscopic deformation and fracture behavior of composites and to manufacturing composites with higher properties. The present work is measurements of the residual stress distributions of the Al matrix near both single SiC continuous fiber and a bundle of SiC continuous fibers in SiCf/Al model composites using micro X-ray beam. Both the hoop residual stresses perpendicular to the radius of the fiber and the radial stresses parallel to the radius of the fiber were measured. The results were compared with those from the finite element method. |
