Objective of this study is the production of nanocomposites by dispersing nanoparticles in liquid epoxy resin. By embedding nanoparticles into the matrix, the reaction kinetics, the curing behaviour and the mechanical properties of the final composite can significantly be improved. In order to prepare the colloidal suspensions, the stressing of particles by shear mixing techniques, turbulent eddies, implosion of cavitation bubbles, ultrasound or impacts is researched. Furthermore the influence of shearing at one plane or in-between two planes is analysed. At this, the process is analysed regarding the maximum processable solids content, the finest product quality, the narrowest width of particle distribution and the minimal provideable specific energy. Finally, the gained experiences are evaluated and used to design an adopted stirred media mill that delivers the finest product quality found during this study. Besides the dispersion parameters, the influence of different formulations is analysed according to the carrier fluids epoxy resin and the corresponding hardener. As particles, aluminium oxide and boehmite in neat and surface functionalised version are used. The dispersibility, the corresponding particle size distribution and the stability behaviour against reagglomeration are analysed according to dynamic light scattering and scanning electron microscopy. Hereby it can be shown that the use of modified particles in combination with epoxy resin delivers the best results.weiterlesen
