AB In this work, an estimation of the reinforcement factor [epsilon] of the Halpin–Tsai equations used to calculate the transverse stiffness E[subíndice 2] is provided. An improved estimation of the value [epsilon]=2 originally proposed by Halpin and Tsai is given through a set of finite element analyses that consider randomly distributed unidirectional fibers for different volume fractions. The analysis overcomes the original hypothesis of a square array distribution of fibers in the transverse plane. It is concluded that a value of [epsilon]=1.5 is a better estimation for the usual volume fractions found in practice for a unidirectional lamina of fiber reinforced composites.
