The problem of orthotropic bi-materials semi-infinite interfacial crack was studied, by constructing new stress functions and using composite complex functions methods of material fracture on z_J plane. It overcame oscillation singularity of stress and existing theoretical solution.When secular equations' discriminations are Δ_1 >0 and Δ_2 >0, the theoretical solutions to the stress fields and the displacements fields of semi-infinite interface crack between two dissimilar orthotropic composite materials near the crack tip are obtained.
