heal.abstract | Theoretical expressions for the prediction of the elastic moduli and thermal expansion coefficients in fiber-reinforced composites were developed. The concept of interphase between fibers and matrix was used for the development of the model. This model considers that the composite material consists of three phases, that is, fiber-interphase-matrix-interphase-fiberinterphase- matrix. The latter is the part of the polymer matrix lying at the close vicinity of the fiber surface. In the present investigation it was assumed that the interphase is inhomogeneous in nature with continuously varying mechanical properties. Different laws of variation of its elastic modulus, Poisson ratio and thermal expansion coefficients were taken into account in order to define the overall moduli of the composite. The results obtained were compared with the respective values of other models as well as with experimental data. | en |
