Research Advances in Microwave Curing Thermoset Resins

The research progresses in microwave curing thermoset resins and their matrix based composites are reviewed,and the following topics,such as the comparative study of microwave curing,heat curing,technology on microwave curing of thermoset resins and thermoset resins modified by fillers and fibers are discussed in details.The results show that microwave curing basically is the same as thermal curing,however,microwave quickens the cure process obviously without posing damages to curing system;thermoset resins can be cured well through adding inorganic,metal particles and fibers to alter the dielectric properties of the system,and controlling microwave process properly.In addition,the principle of microwave heat-effect,the development and application of microwave heating are prospected.
