SANDWICH STRUCTURE AND ASSOCIATED PRESSURE-BASED FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a honeycomb sandwich structure that can be formed to assume contours required by a particular application.SOLUTION: A method of forming a sandwich structure 100 includes the steps of: providing the sandwich structure 100, which comprises a core 102 positioned between a first water-impermeable sheet 104 and a second water-impermeable sheet 106; positioning the sandwich structure 100 in a cavity of a die assembly; and pressurizing the core 102 to expand the sandwich structure 100 into engagement with the die assembly.SELECTED DRAWING: Figure 2A
