This review reports about the most used glass matrices (2) and reinforcements (3) for the preparation of glass- and glass-ceramic composites, their preparation methods (4), their properties (5) and the foreseen applications (6) in the field of transports, aerospace and biomedical. In particular, the thermal and mechanical properties of glass- and glass-ceramic matrix composites are compared with those of the most common metals and ceramics. Finally, some comments are reported about the probable development of the research in this field of great technological importance (7).
