Pyramid waffle core structure and method of fabrication
A structural core and associated method of forming such structure is disclosed. The structure includes a single layer of at least two rows of hollow pyramid-like structures. The hollow pyramid-like structures dampen acoustic noise and provide a trusslike structure that provides a high level of stiffness against transverse loads, shear stresses and side-loading. The hollow pyramid-like structures preferably have upward facing and downward facing open bases, and are formed in rows and columns. To aid in sound attenuation, the single layer is formed from a partially porous material, a woven thermoplastic, woven carbon fiber, fiberglass and paper. To provide additional structural integrity, the single layer is formed from a solid non-porous material such as a metal. The structural core may be included within outer panels to form acoustical or structural panels.
