Abstract

An analytical method has been presented in this study to predict the flexural modulus of misaligned short-fiber-reinforced polymers (SFRP) by taking into account the effects of fiber-length and fiber orientation distributions. The fiber-length distribution (FLD) and the fiber-orientation distribution (FOD) were modelled by using two probability density functions as done previously. The laminate analogy approach was used to derive the expression for the flexural modulus of SFRP as a function of the FLD and the FOD. The cases of uniform FOD, continuous FOD and layered structure were considered. The effects of the FLD (and hence the mean and mode fiber aspect ratio) and the FOD on the flexural modulus of SFRP have been discussed in detail. This theory was then applied to some existing experimental results and the agreement was found to be satisfactory.
