Abstract:
1. A microstructured composite material with controlled deformation comprising: a matrix material, the matrix material being a variable elastic modulus material selected from the group consisting of shape memory polymer, phase changing metal, wax, ice, electrorheological fluid, magnetorheological fluid, electrostrictive material, magnetostrictive material, ferromagnetic magnetostrictive material, magnetorheological elastomer, electrorheological elastomer, and liquid crystal elastomer; at least three reinforcement layers embedded in the matrix material, each of the at least three reinforcement layers comprising a plurality of flat coplanar platelets arranged along a plane of the matrix material, the at least three reinforcement layers comprising a first reinforcement layer comprising a plurality of flat coplanar first platelets arranged along a first plane of the matrix material; a plurality of flat connecting members having a flat surface extending in a thickness direction crossing the first plane and interconnecting the plurality of flat coplanar first platelets along the first plane of the matrix material, each of the flat connecting members connecting a corresponding two of the flat coplanar first platelets and having a greater height in the thickness direction than that of the corresponding two of the flat coplanar first platelets; and means for mechanically coupling stress between adjacent layers of the at least three reinforcement layers to mitigate out-of-plane deformation of the matrix material while allowing deformation of the matrix material along the first plane.
