The Demonstrator is based on the Flectofold and the ITECH Research Demonstrator 2018-19. In contrast to the Flectofold, the curved folding lines are dispensed here and, analogous to the ITECH Research Demonstrator 2018-19, integrated pneumatic cushions are used for motion control.
The elements are made of glass fiber-reinforced plastic (GFRP) with a polyamide matrix. During the production of the elements, a cavity is formed in the laminate asymmetrically in relation to the mirror plane of the laminate. A cushion is inserted into this cavity. Due to the expansion of the cushion, the laminate is more shortened on the more flexible/thinner side, so that the elements bend in this direction.

The demonstrator for the “Kunststoffbildungspfad” of the Max-Planck-Institute in Mainz consists of 10 elements, each with two pneumatic chambers for actuating the related flaps. The visitor of the exhibition can apply air pressure to the cushion via a foot pedal and thus control the movement. An air pressure of 0.5-1 bar is sufficient to actuate the elements.
