"WebNote that the Halpin-Tsai and Nielsen equation for longitudinal Young’s modulus share the same formulation as that of rule of mixture. In composite system less stiff polymer matrix is replaced by stiffer fiber material. Thus it is obvious that as fiber percentage increases the composite become stiffer and gives higher Young's modulus. " - Buckypaper polymer composite halpin tsai
