Disclosed herein are engineered microscale particle based material suitable for applications that can benefit from a microscale particle based material capable of interacting with or responding to, in a controlled or predetermined manner, changes in its surrounding environment. The microscale particle based material generally includes a densely packed particle structure including densely packed microscale particles, wherein particles of the densely packed particle structure are positioned with respect to each other such that at least some of the particles get into contact with each other during interaction with a compression wave, thereby attenuating the compression wave propagating in the densely packed particle structure.

Disclosed herein are engineered composite materials suitable for applications that can benefit from a composite material capable of interacting with or responding to, in a controlled or predetermined manner, changes in its surrounding environment. The composite material is generally includes a gradient layer structure of a sequence of at, e.g., three or more gradient-contributing layers of microscale particles, wherein a mean particle size of particles of neighboring gradient-contributing layers in the cross section of the gradient layer structure varies from layer to layer, thereby forming a particle size gradient, and in contact with the gradient layer structure, a densely packed particle structure including densely packed microscale particles, wherein a mean particle size of the densely packed microscale particles does not form a particle size gradient in the cross section of the densely packed particle structure.

Abrégé

Disclosed herein are engineered composite materials suitable for applications that can benefit from a composite material capable of interacting with or responding to, in a controlled or predetermined manner, changes in its surrounding environment. The composite material is generally comprised of one or more layers whereby each layer is comprised of a plurality of particles having a predetermined median particle size diameter. The predetermined media particle size in each layer, when viewed in cross section, can form a particle size gradient such that the median particle size of each layer sequentially decreases (or increases) across the cross section of the material. Particles can further be core-shell particles releasing their core material upon actuation.
