Modelling a new composite from a recycled GFRP

The mechanical reprocessing of different types of plastic scrap in high-energy disintegrator mills in direct and selective milling systems is considered. The grindabilty and separation of components of composites-an acrylic plastic and glass fibers-are analyzed. The relation between the density of the filler material and the fractions of a polymethylmethacrylate powder is modelled on the basis of experimental data. Artificial neural networks and a hybrid genetic algorithm are used to design a new composite from a recycled glass-fiber-reinforced plastic.
