Ceramic reinforcements for composites
J. Lamon, CNRS/National Institute of Applied Science (INSA Lyon) France
Ceramics need to be reinforced because of their inherent brittleness and lack of reliability. Only continuous fibers are able to arrest the cracks through deflection at fiber–matrix interfaces. Only those fibers that can withstand the high temperatures required by composite processing (> 1000 °C) without significant damage can be used. Efficiency of reinforcement depends strongly on interface/interphase characteristics. Features of the mechanical behavior, as well as the influence of reinforcement on composite mechanical behavior and properties, are also discussed.
