Abstract: The composites involving unsaturated polyester resin (UPR) and nanometer ceria (n-CeO2)were prepared by ultrasonic and three-roll muller mixing method. Compared with un-grinding, the tensile strength of n-CeO2/UPR composites prepared by grinding, increased by 31.8%, and nanometer particles had better dispersion in the composites. Through the postcure treatment of n-CeO2/UPR composites, infrared spectra showed that the composites had the best performance with the treatment at 60℃ by two hours, and compared with strength of samples at room temperature, the tensile strength increased by 53.6%. When the content of n-CeO2 is 2 wt %, the tensile strength was improved, which increased by 9.7%, compared with pure UPR.
