Abstract:

Inorganic and organometallic polymers capable of giving ceramics in good yield (at least 50%) when subjected to pyrolysis are referred to as “preceramic polymers”. There are several advantages in using preceramic polymers for obtaining ceramics. Using conventional ceramic processing techniques it is difficult to get non-oxide ceramic coatings, continuous ceramic fibres and ceramic films. Preceramic polymers can be processed using conventional polymer processing techniques into coatings, films, fibres and composites followed by pyrolysis and sintering to get ceramic coatings, ceramic films, ceramic fibres and ceramic matrix composites (CMCs). Unlike the conventional ceramic processing routes, preceramic route invariably give nanoceramics and hence, it is easy to machine polymer-derived ceramic components.Yet another advantage is that conversion of polymers to ceramics takes place at relatively low temperatures (1200-1500°C) when compared to conventional processes (~2000°C).Keeping in view of the potential space applications, the research work on polymer-derived ceramics was initiated in the Space Centre in 1987 and over the years, different types of preceramic polymers such as polycarbosilanes, polysialhydrocarbons, polyborosiloxanes, and poly(metalloborosiloxane)s have been synthesized and their conversion to ceramics have been studied. These precursors have been evaluated for the following space applications: i) oxidation resistant coatings for C/C composites for renetry and reusable launch vehicles, ii) matrix resins for ceramic matrix composites and lightweight ceramics, candidate materials for advanced thermostructural/thermal protection materials for reusable launch vehicles, iii) thermal barrier coatings, iv) ceramic adhesives and v) atomic oxygen resistant coatings for low earth orbit space structures. This keynote lecture covers the above aspects.

Abstract:

Today advances in automotive, aerospace, defense, and energy industries demand new composites and materials with superior combinations of light weight, high performance, affordability, and versatility. This promotes the development of functional nanomaterials which integrate at least one other function beyond the mechanical aspect. Functional nanocomposites can be designed by integrating thermal, electrical, magnetic, optical, mechanical and possibly other functionalities to provide a unique combination of the individual capabilities. Engineered functional nanocomposites have been proposed to improve the dispersion and increase the volume fraction of reinforcing phases over conventional composites. The functional nanocomposites exhibit unique functionalities with a wide range of potential application which is the focus of this lecture.
