Abstract

In this study, the interfacial properties between silica glass fibers and suffonated polystyrene ionomer as well as polystyrene (PS) was studied by conducting single filament pullout tests. SEM pictures of the fracture surface of glass-ionomer (or PS) composites were also obtained to provide additional information on the adhesion between the fibers and the matrix. The ion-dipole interactions were utilized to enhance interfacial adhesion in fiber reinforced composites. Through introduction of ionic groups on polystyrene, the interfacial shear strength was found to increase significantly as the ion-dipole interactions were increased. The fractional shear strength also increased significantly as the ion content was increased. These results suggest the possible usefulness of ionomers as a thermoplastic matrix of fiber reinforced composites.
