In this study, both a elastic and a viscoelastic constitutive relations are considered for the matrix. Time dependent strains and stresses of the fiber, interphase and matrix are computed and the interaction between the fiber and matrix is examined. Effective Young's moduli for composites are evaluated. Effects of the viscoelastic interfacial layer on the average transverse Young's modulus are also investigated. The Numerical evaluation shows that the effective transverse Young's modulus of fiber-reinforced composites are significantly affected by the fiber volume faction ratio and viscoelastic behavior of the matrix.
