Modulus prediction of a polymer matrix composite reinforced with fly-ash hollow microspheres

  • Based on a self-consistent three-phase model and Mori-Tanaka theory, general expressions are deduced to calculate the effective volume modulus and the effective shear modulus of a composite containing several sorts of hollow microspherical reinforcements. Then, the effective modulus of a polymer matrix composite reinforced with fly-ash hollow microspheres is predicted, as a function of the volume fraction, the average size and the inner pressure of the microspheres. The calculated results agree with experimental measurements satisfactorily, suggesting that the modulus of the composite is determined mainly by the volume fraction and the average size of the microspheres, while the effect of their inner pressure is negligible.
