abstract This paper was written and formulated based on the micromechanical analysis of unidirectional glass fiber reinforced epoxy composite lamina. To simplify the calculations and achieve acceptable results, a few assumptions like idealized packing, the representative volume element (RVE), uniform strain boundary condition, statistically homogeneous unidirectional fiber reinforced composites, etc. are taken into consideration. Translational symmetric transformation was applied and established mathematical models are presented to obtain the values of the effective material properties by means of the simple strength of materials approach so that they can be compared with the semi-empirical model. In addition, a parametric study was carried out to verify the dependency of the fiber and matrix on the overall effective material properties. This will ultimately help to develop the required glass fiber reinforced epoxy composites for their specific applications.
