Abstract:
A damage resistant sandwich panel having a first outer face sheet for forming an outer face, a second inner face sheet for forming an inner face, and a core sandwiched between the first outer face sheet and the second inner face sheet. The core is a corrugated sheet having a plurality of elongated crests, a plurality of elongated valleys, and bridging core material between the elongated crests and the elongated valleys. This bridging core material is disposed at acute angles relative to each of the elongated crests and the elongated valleys. The first outer face sheet, the second inner face sheet and the core are constructed from a material having a tensile yield strength (elastic limit) in excess of 20,000 psi and a tensile strain to yield ratio exceeding 2. 0%; a preferred material is fiber glass. The elongated crests of the core are fastened to the outer face sheet and the elongated valleys of the core are fastened to the inner face sheet to provide a first and largest spatial separation between the outer face sheet and the inner face sheet.
