Abstract

This study had two aims: to develop prospective techniques for recycling of composite plastic scrap and to find potential application areas for secondary raw materials. The method of collision was selected to treat composite plastic wastes, using a disintegrator mill. In our experi­ments, the particle size of acrylic plastic was reduced and glass fibres were separated. The paper describes the results of materials separation, granularity of the milled material and morphology of the plastic powder particles. To develop new filler materials for filler–resin systems, plastic powders with different granularity were used. Mechanical properties of new composite materials were examined. The developed new acrylic powder filler materials are prospective for use in the filler–resin systems to reinforce acrylic shells.
