Abstract:

A literature search covering the period 1957-1978 was carried out in order to identify inorganic, metallo-organic, and hybrid inorganic-organic polymers that could serve as potential matrix resins for advanced composites. The five most promising candidates were critically reviewed and recommendations made for the achievement of their potential in terms of performance and cost. These generic polymer classes comprise 1 Polyarylsilsesquioxanes, 2 Polysilylarylene-siloxanes, 3 Poly silarylenes, 4 Poly silicon-linked ferrocenes, and 5 Polyorganophosphazenes. No single candidate currently possesses the necessary combination of physico-mechanical properties, thermal stability, processability, and favorable economics. The first three classes exhibit the best thermal performance. On the other hand, polyorganophosphazenes, the most extensively studied polymer class, exhibit the best combination of structure-property control, processability, and favorable economics. jg p5
