Description
Summary:The microstructures and the properties of a CTBN rubber toughened tri functional glycidic ester (TGE) epoxy resin dual-phase system were studied. The SEM micrographs show that the CTBN rubber-modified TGE epoxy resins are composite materials consisting of a continuous phase of epoxy resins and a CTBN rubbery disperse phase. For the case of 120°C pre-reacted 20% CTBN modified epoxy resins, the rubber particles have a dual-phase structure, containing an appropriate amount of epoxy resin particles, along with the best combination of strength and toughness.
