Biodegradable self-reinforced composite materials; Manufacturing structure and mechanical properties

Abstract

Biodegradable (or absorbable), self-reinforced polymeric composites fulfil the demands of secure orthopaedic fixation materials because of their high strength, appropriate stiffness and strength retention which can be tailored according to the healing rate of damaged tissues. Ultra-high strength, self-reinforced, macroscopical biodegradable polymeric composites can be manufactured by creating the polymeric microstructure, where oriented reinforcing elements and matrix material, which have the same chemical element composition, are bound together. Biodegradable, self-reinforced composites have attractive application possibilities in surgery. The materials can be processed into the form of rods, screws, tacks, cerclages, clamps, plates, spirals, etc., which have versatile applications in traumatology and in orthopaedic surgery.
