In this project, the characterization of the microstructures, damage and fracture behavior of CFRP using state-of-the-art X-Ray Computed Tomography (XCT) was investigated experimentally in order to develop an innovative multiscale fracture mechanics (MustFrame) framework and associated computer codes for accurately modeling the damage and fracture in these materials in order to critically evaluate the reliability and performance of small- to large-scale engineering structures and systems. The ultimate aim is optimize microstructures and structural designs for better quality, greater reliability and lower cost. The funded research led to three PhD theses.
