초록
In this study, glass fiber-reinforced vinyl ester (VER/GF) composites were preparedfrom VER/GF prepreg by vacuum bagging process. The post-curing of VER/GF compositeswere performed by electron beam irradiation with a variety of absorbed doses. The mechanicalproperties of VER/GF composites were dependent on the absorbed dose. The analytical resultsshow that the post-curing by electron beam resulted in the enhancement of the flexural strengthand modulus, tensile strength and modulus, and thermal stability. The mechanical properties ofVER/GF composites post-cured by electron beam were superior than those of VER/GF compositespost-cured by heat treatment. Therefore, post-curing by electron beam irradiation is an effectiveand powerful method to the mass production of VER/GF composites.

The mechanical properties ofVER/GF composites post-cured by electron beam were superior than those of VER/GF compositespost-cured by heat treatment.
