ABSTRACT:
A composite material is provided that includes a matrix material, and a plurality of deflectable elements or “machines” disposed in the matrix material, the machines acting to modify one or more physical properties of the composite material in response to forces acting upon the composite material. Preferably, the machines have an elongate shape defining a longitudinal axis, which are disposed within the matrix material in a predetermined array. The elongate members have an asymmetrical cross-section which is deflectable between first and second shapes, and consequently the composite material exhibits different physical properties because the elongate members deflect between the first and second shapes. The machines may include a variety of asymmetrical cross-sections, such as a generally “Z” shape, an hourglass shape, a cantilever shape or a leaf spring shape.
