In this work, a mathematical model for the multi-component diffusion of reacting thermosets into amorphous thermoplastics is presented for the epoxy–amine-polysulfone (PSU) system. The governing Fickian diffusion-reaction equations for the epoxy and amine are strongly coupled through the amine concentration dependence of the epoxy diffusivity and the autocatalytic reaction terms for the epoxy and...
In this work, a diffusivity model based on free volume theory is presented for the simultaneous diffusion of diglycidyl ether of bisphenol A (DGEBA) epoxy and bis(p-aminocyclohexyl) methane (PACM 20) amine monomers into amorphous polysulfone (PSU). This model is expected to predict and explain the diffusion behavior of the epoxy and amine monomers into PSU during the initial time periods. The overall...
Multi-component diffusion of a diglycidyl ether of bisphenol A (DGEBA) epoxy and an aliphatic diamine, bis(p-aminocyclohexyl)methane (PACM 20) into amorphous polysulfone (PSU) using a Fourier Transform Infrared Spectroscopy-Attenuated Total Reflectance (ATR-FTIR) technique has been studied. Results indicated that the diffusion of the larger epoxy molecule in polysulfone occurred more quickly when...
