Abstract
Polyethylene Glycol (PEG-1000) was considered as an effective thermoplastic filler for epoxy systems. Current study tries to portray both the reinforcing and catalytic efficiency of PEG-1000 in the Diglycidyl ether of Bisphenol A based epoxy (DGEBA) and Diethyl toluenediamine (DETDA) based system. The effectiveness of the combination of PEG/DGEBA/DETDA this trio system in the epoxy toughening were also elucidated systematically. PEG-1000 enhanced tensile strength and fracture toughness of epoxy by 8.7% and 213%, respectively. The thermo-mechanical characteristics of the PEG/epoxy systems were thoroughly investigated with the help of theoretical models.
