碩士 === 淡江大學 === 化學工程與材料工程學系碩士班 === 104 === Epoxy resin (epoxy resin) is widely used as a thermosetting resin, but has bad impact esistance, unable to meet the requirements of the project, so we study the organogels(DBS/DGEBA),then add the curing agent,we hope that we can improve the toughness of epoxy resins, but also by changing the content of DBS discuss the structure of the organic gel, rheological properties, thermal properties and the molecular forces. By Rheological analysis results that with the increase of the DBS, have shown that elastic modulus G ''can effectively enhance , and add the curing agent also can show that increase of the DBS also can increase the curing time .TEM and SEM we can observed DBS self-assembly to formed the 3-D network of DBS even add curing agent also can seen the fibers is still exist inside , improve the properties ,and the mechanical properties can be observed significantly improved its toughness when DBS added to 4wt%
