The Controlled Thermal Expansion model predicts some of the properties exhibited by a novel type of lattice structure which uses two materials in a specific geometry to control the thermal expansion coefficient.
These lattices are still in the developmental stage and not commercially available. The Controlled Thermal Expansion model is a tool to investigate the theory and predict how this type of lattice may behave. Previous research work has been carried out on 2D lattices, however this model deals with 3D lattices.
The attraction of these lattices is that through optimization of the geometry (assuming suitable lattice materials have been chosen), the coefficient of thermal expansion can be controlled (it can be made zero or even negative). This is while remaining structurally robust, as they are stretch dominated lattices.
