Introduction: Ceramic composites provide a lightweight alternative to metal alternatives for various components of high stress systems. These composites tend to have a high temperature tolerance but may lack the toughness required for certain applications. Many techniques have been tested to increase the strength of these ceramics, often resulting in non-practical cost increases.

 

Technology: The proposed method is the first every to apply graphene platelets to ceramic composites for increased fracture toughness. The toughening mechanism involves crack deflection in three dimensions. This is a novel approach never demonstrated before in this field.

 

Advantages:

•       Lightweight materials

•       High temperature tolerance

•       Increased stress tolerance

 

Applications:

•       Hot turbine engines

•       High end brake discs

•       Nuclear reactor components
