In this paper, stresses around an interface crack in carbon-fiber-reinforced plastic composites are analyzed. It is assumed that the material properties of the carbon fiber obey anisotropy, while those of the plastics obey isotropy. Boundary conditions are reduced to four simultaneous integral equations. To solve the equations, the differences of the crack surface displacements are expanded in a series of functions which are zero outside of the crack. The unknown coefficients which are accompanied in that series are solved with the aid of the Schmidt method. Neither oscillating stress singularities nor material overlaps appear in this solution, and physically acceptable stress intensity factors are obtained.
