【 摘 要 】

This paper presents experimental research which has confirmed the benefits of the new technology of curing polymer matrix for both laboratory and full-scale components, and compares with polymerization in an electrical-heated oven. Strength tests of small size specimens made of organic polymer determined that after microwave heating samples are capable of withstanding 1.3 greater loads than after heating in an electric furnace. Flexural modulus of full-scale specimens of organo-plastic, which were cured in a microwave radiation field showed greater modulus than samples which were polymerized in an electrical-heated oven at 40% and 20% respectively. The microstructure of the samples treated in the electric furnace were found to be porous, inhomogeneous, binding in large portions mixed up with pores spotted, accumulates on the edges and a separate central zones. Polymerization in microwave oven however, gave a microstructure which is more uniform and the binder distributed throughout the volume.
