Abstract

Since relationships between the structure and properties of ceramic-graphene composites are still not sufficiently defined, some numerical methods may facilitate the design of optimal material for new applications. In order to investigate such relationships, the methods for modelling the structure of composites with different sizes, shapes and spatial distributions of MLG (multilayer graphene) in the ceramic matrix have been developed. Using advanced methods of sintering SPS (Spark Plasma Sintering), two kinds of Al2O3 matrix composites were prepared with the participation of multilayer graphene flakes up to 2 wt.%. (3.56 vol.%). Studies of the microstructure and the basic mechanical properties suggesting a very strong impact of graphene flakes within a range of small volume additions. Thus there is a clear deterioration of the properties of composites with volume shares exceeding 1%, which may be due to changes of the graphene nanoplatelets and agglomerates shape.
