“…The fiber/matrix interphase guarantees the stress transfer from the "weak" matrix to the "strong" fiber and from fiber to fiber through the matrix, as well. The term interphase, meaning a finite interlayer with distinct physico-chemical properties between the fiber and matrix, has been introduced in the 1970s [1]. The interphase controls the interactions between fiber and matrix and thus also the mechanical property profile of structural composites.…”

“…At this point, we should note that since the interphase is an altered matrix and thus there is no addition of other materials in our final model, the radii a,b,c,d of the 4 -phase model introduced in the previous Section, also appear in the proposed 7 -phase model and now have just been renamed as 1 r 3 r 5 r 7 r respectively. Hence, in the above relations we have expressed the interphase radii of the 7 -phase cylindrical model in terms of the radii b,c,d of the 4 -phase one, which does not contain any intermediate phase.…”

“…Some of them take into account the existence of an intermediate phase, developed during the preparation of the composite material and which plays an important role on the overall thermomechanical behavior of the composite. In a model developed by Theocaris et al [1,2] this intermediate phase has been considered initially as being a homogeneous and isotropic material. In a better approximation [3] a more complex model has been introduced, according to which the fiber was surrounded by a series of successive cylinders, each one of them having a different elastic modulus in a step-function variation with the polar radius.…”

“…In a simplified approach which was adopted in previous papers [7,8], this natural intermediate phase was assumed to be a homogeneous and isotropic material, whereas in another groups of studies [9][10][11] more advanced and prominent models were introduced, the main feature of which was the fibre to be occupied by a series of successive coaxial cylinders, each of which has a different stiffness in a step-function variation in terms of polar radius. Further, a valuable experimental study towards the estimation of mechanical and thermal properties of unidirectional fibrous composite materials was carried out by Clements and Moore [12] whereas a theoretical and experimental investigation of mechanical properties of polymeric particulate and unidirectional fibrous composites by the interphase concept was performed in a previous paper [13].…”
