Lightweight rigidly foldable canopy using composite materials

Rigidly foldable origami gadgets and tessellations

Rigidly foldable origami allows for motion where all deflection occurs at the crease lines and facilitates the application of origami in materials other than paper. In this paper, we use a recently discovered method for determining rigid foldability to identify existing flat-foldable rigidly foldable tessellations, which are also categorized. We introduce rigidly foldable origami gadgets which ...

Foldable Composite Structures

This paper presents a study of the folding of a new self-powered, self-latching tube hinge for deployable structures. This hinge is made by cutting three parallel slots in a thinwalled carbon fibre reinforced plastic (CFRP) tube, thus leaving three tape springs connecting the two ends of the tube.

Vibro-acoustic analysis of lightweight composite panels with damping materials

In this paper a numerical model to study the vibro-acoustic behavior of a laminated plate backed by a poroelastic foam layer is developed. Such approach consists on a coupled mitigation strategy aiming either mechanical vibration suppression or acoustic attenuation as well. The laminated plate model consists of fiber laminae with interleaved viscoelastic layers in standard constrained or integr...

Cutting edge: thin, lightweight, foldable thermochromic displays on paper.

In this issue of Lab on a Chip, Siegel et al. present a novel method for electronic control of displays on paper substrates. The authors micropatterned electrically conductive wires on one side of the paper, and coated thermochromic ink on the other side. This combination of materials allows a clever operation: as current flows through the wires to achieve localized resistive heating, dye in th...
