Stiff lattices with zero thermal expansion
Source abstract
Abstract
Lattice microstructures are presented with zero coefficient of thermal expansion. These are made of positive expansion materials. The behavior is primarily stretch dominated, resulting in favorable stiffness. The behavior of these lattices is compared with that of triangular and hexagonal honeycombs in a modulus–density map. These lattices do not undergo thermal buckling, in contrast to designs based on sublattices.
