Development of B4C-matrix Ceramic Composite Systems for Lightweight
Defence/Aerospace Applications


Supervisor: Assoc Prof. Dr. Buğra Çiçek

Ceramic-matrix composites (CMC) can be used under various conditions which necessitate
high hardness, low density, high thermal/chemical resistance and semiconducting capability.
Different combinations of oxide and non-oxide ceramic materials were used to develop CMC
systems to provide specific characteristics for designated missions [1]. B 4 C tend to show
ultra-high hardness, low density and high wear resistance which makes it ideal for armor
applications and cutting tools [2]. B 4 C-matrix ceramic composite systems can offer improved
properties compared to monolithic B 4 C such as; improved fracture toughness, higher
strength and improved amorphization behaviour under impact or load. The aim of this study
is to develop lightweight B 4 C-matrix ceramic composite systems via hot pressing or reaction
sintering methods for lightweight armor and aerospace applications.
