Microwave processing of polymers and composites - Fundamentals and applications

    Research output: Research - peer-reviewArticle

    Abstract

    Research has been conducted to investigate the mechanism of microwave enhancement of reaction rates. One approach is the comparative study of microwave curing of three epoxy systems to test the existence of "non-thermal effects". Another is the study of the temperature distribution at molecular level inside the material with microwave thermal-mechanical analysis system to investigate the effect of "localized superheating". Several microwave process concepts have been investigated to address the issue of the industrial application of microwave processing technology. Variable frequency approach has been studied to achieve intelligent control for uniform and fast material processing. A Part-Shaped mold has been designed and patented for RTM process. Microwave adhesive bonding has been evaluated.
