Publication number: 20180272588Abstract: Issues with pleat walled honeycombs are solved by replacing polygonal creases with curved creases. As with a conventional straight-walled honeycomb, these strips can be combined into a space-filling honeycomb structure. The benefits of these curved creases are threefold. First, the stress concentrations mentioned above with pleat-walled honeycombs are mitigated. The stress due to finite material thickness is spread more evenly over the crease line, instead of being concentrated at a point, as with pleat walled honeycombs. As a result, the maximal value observed is lower and the adverse effects are reduced. Second, the curved creases also serve to give better control over material properties, and third, the curved crease honeycombs do not require any of the horizontally-running creases. The curves are typically mathematical curves that can be computed algebraically or by solving a differential equation.Type: ApplicationFiled: March 23, 2018Publication date: September 27, 2018Applicant: Massachusetts Institute of TechnologyInventors: Samuel E.
