Résumé
The thermal stability, fracture toughness, flexural strength, and surface morphology of a polysulfone (PSF)-modified epoxy resin were investigated using several techniques. The thermal stability of the PSF-modified epoxy resin was similar to that of the neat epoxy resin. The flexural strength of the epoxy resin decreased with the addition of the PSF. The fracture toughness of the PSF-modified epoxy resin significantly improved compared to that of the neat epoxy resin. The SEM micrograph of the modified epoxy resin showed a relatively rough surface with shear deformation and tortuous cracks, thereby inducing higher fracture toughness in the PSF-modified epoxy system.
