DEFORMABLE STRUCTURE FOR ABSORPTION OF ENERGY FROM MECHANICAL AND/OR ACOUSTIC IMPACTS
First Claim
Patent Images
1. A deformable structure for absorbing energy from at least one of a mechanical or acoustic impact comprising:
- an inner core andone or more external layers covering the inner core,the inner core comprising a set of first segments having a positive Poison'"'"'s ratio and second segments having a negative Poisson'"'"'s ratio;
the first and second segments being arranged alternately and joined between them so that a deformation received by one first segment is transmitted to an adjacent second segment and vice versa.

Abstract
A deformable structure, such as a panel or a shock absorber, for absorbing energy from a mechanical and/or acoustic impact. The structure comprises an inner core and one or more external layers covering the inner core. The inner core comprises a set of first segments having a positive Poison'"'"'s ratio and second segments having a negative Poisson'"'"'s ratio. The first and second segments are arranged alternately and joined to one another so that the deformation received by one first segment is transmitted to an adjacent second segment and vice versa.
