COMPOSITES BASED ON GLASS FIBRES AND SILOXANE MATRIX AS A PROMISING BIOMATERIAL

摘要

Composite materials designed to serve as substitutive or connective elements in orthopedics must be biocompatible and their mechanical properties should approach as much as possible the properties of the human bone (the strength characteristics should be at least the same and the modulus of elasticity should be close to the value characterizing the human bone). The project aims at a simple and therefore a relatively inexpensive preparation of composite substitutive materials for bones on the basis of commercially available glass fabrics and siloxanes, with a high strength in bending, with a low elasticity modulus close to that of human bone, however, with a considerably porous, i.e., open surface, which would exhibit bioactivity, i.e., give the possibility of down-growth especially of the bone tissue. In other words, the preparation of a composite on the basis of inert components but with a bioactive surface.
