AB  - Microwave curing technology has been widely used in resin and its composite 
      materials. In order to study its effect for curing unsaturated polyester resin 
      (UPR) composites containing calcium carbonate (CaCO(3)) filler, this paper first 
      investigated the influence of microwave power and microwave irradiation time on 
      the curing characteristics of UPR. Then, CaCO(3) particles were added to the UPR 
      to investigate the microwave curing effect of the UPR composites containing the 
      CaCO(3). The results showed that microwave irradiation could heat the UPR sample 
      evenly, and rapidly cause the chain growth reaction, thus greatly shortening the 
      curing time. The curing degree and products of the samples after microwave curing 
      were consistent with that of the thermal curing. The addition of CaCO(3) 
      particles could increase the heating rate of the UPR composites, which would 
      accelerate the curing rate of the UPR. However, higher microwave power could lead 
      to pore defects inside the UPR composites with higher CaCO(3) content, resulting 
      in a lower strength. Thus, the compactness of the samples should be improved by 
      reducing the microwave power and prolonging the microwave treatment time.
