The concept of fracture mechanics is applied to analyze the brittle fracture of unidirectional composites. The analytical prediction based on the newly developed S c -theory agrees well with the experimental data on Scotchply 1002 where crack propagation occurs along the fiber direction. The S c -theory represents a departure from the classical stress-intensity factor K c concept in that it is designed to treat the mixed mode fracture problem while the K c -theory is limited to Mode I crack extension.
