Sažetak
This article reviews the fracture problems of polymer materials for removable prostheses and the need for its reinforcement. The historical development of different attempts to strengthen the polymers all the way to the fiber-reinforcements is presented. Different materials can be used for polymer reinforcements: carbonated, aramidic, polyethylene and glass fibers, which are today most frequently used, creating composite materials with enhanced properties. Main features of the fibers in composites are greater rigidity and strength while the matrix provides the protection of the fibers as well as their position that gives the composite material the best properties. The border between the fiber and the matrix is somewhat dubious in a sense that there are often microfractures, caused by inclusion of air or impurities during the production process of composites that can weaken the mechanical properties of the material. Treating the fiber surface with adhesive agents, especially silanes, in order to enhance the grip between the fibers and polymer matrix, enhances the quality of the border.
