Title: Cellular core structural panel components, structural panel formed therefrom and method of making

Abstract: Disclosed is a cellular core structural panel, comprising a plurality of bonded stacked segments, each segment being formed from a sheet characterized by a top portion having repeating peaks and troughs and sidewalls integral with the troughs. The cut-to-length segments are successively aligned so that each peak contacts the trough of the segment above it to form a cellular core panel with integral face sheets formed from the sidewalls of each segment.
