Abstract: Compression modulus is one of the key mechanical properties of epoxy resin composites filled with hollow glass microspheres, the prediction of compression modulus has certain engineering research significance. In this paper, the compression modulus of epoxy resin composites filled with different volume fraction of hollow glass microspheres were experimentally investigated, followed by the comparison with the predicted values using Nielsen model and the linear model as well as the square law summation model. The results show that the theoretically predicted values using linear model exhibit the lowest error for samples with volume fraction of hollow glass microspheres exceeding 30%. However, for samples with lower volume fractions, the predicted values deviate significantly due to the obvious misattribution of glass microspheres. In contrast, the Nielsen model provides relatively accurate predictions for samples with lower volume fraction of hollow glass microspheres. Among the three models, the square law summation model exhibits the largest deviation in estimating the compression modulus of epoxy resin composites filled with hollow glass microspheres.
