An analytical model is formulated which attempts to account for the axial and the interfacial shear stresses which can develop in hybrid fiber composites due to the mismatch in coefficients of thermal expansion and Youngs modulus. A finite width hybrid composite monolayer with alternating high modulus and low modulus fibers is considered. To properly account for the interfacial shear between fiber and matrix, a modified shear lag model is used, which permits extensional deformation in the matrix in the fiber direction. Typical stresses due solely to temperature changes are calculated, and show steep boundary layer edge stresses at free corners.
