Influence of Maleinized Polybutadiene on Adhesive Strength and Toughness of Epoxy Resins

This study explored the effect of maleinized polybutadiene (MPB) on mechanical properties epoxy resins. Diglycidyl ether bisphenol-A, an resin, was modified by incorporating MPB having different molecular weights in order to improve fracture toughness and peel strength. mixed with resin at several concentrations (5, 10, 15 phr), as major phase minor phase. A comparative performed investigate influence resins based their weight difference. Lap shear test results showed that strength MPB-modified superior neat resin. At 10 wt% loading, exhibited 87% enhancement T-peel relative Moreover, energy system increased proportionally amount matrix. These indicate incorporation is a simple effective method for designing multifunctional resins, thus facilitating industrial application various spheres.
