Two-dimensional problems involving anisotropic piezoelectric composite wedges and spaces were studied. The Stroh formalism was used to obtain the basic real-form solution in terms of two arbitrary constant vectors for a particular wedge. Explicit real-form solutions were then obtained for a composite wedge which was subjected to a line force and a line charge at the apex of the wedge, and to a composite space which was subjected to a line force, line charge, line dislocation and an electric dipole at the center of the composite space. In the case of the composite wedge, the surface traction on any radial plane, and the electric displacement normal to the radial plane, vanished everywhere. In the case of the composite space, these quantities did not always vanish but they were invariant with respect to the choice of the radial plane.
