【Abstract】 To predict the shrinkage rate of nano-meter CaCO3/POE/PP composite, the samples of the materials were collected from the experiments, in which the composites were prepared with different content of nano-meter CaCO3 at the same molding condition. A GM ( 1, 1) model was proposed to forecast the shrinkage rate of the composites with different content of nano-meter CaCO3. The calculated results were close to those from the experiments and the sample error was within the range of the engineering permissibility, which confirmed the feasibility of the model.更多还原
