Description:

Ceramic matrix composites reinforced with thermally stable silicon carbide or alumina fibres will be manufactured and investigated. Low-cost polymers will be used as matrix precursors. The composites performance at elevated temperatures in an oxidative environment (air) will be assessed by non-destructive testing, evaluation of the fibre/matrix interface bonding, and strength measurement. Composite construction and processing parameters leading to favourable mechanical properties and reasonable thermal stability will be pursued.
