Abstract

Abstract Translated from German Folienverbund, bestehend aus mindestens zwei beabstandeten Folien, die an mehreren Stellen zur Ausbildung von Kammern miteinander verbunden sind. In den Kammern sind chemische Stoffe enthalten, die durch äußere Einwirkung eine chemische Reaktion ergeben, die zu einer Vergrößerung des Volumens der Kammern führt. Foil composite, consisting of at least two spaced foils, which are connected to one another at several points to form chambers. The chambers contain chemical substances which, due to external influences, result in a chemical reaction which leads to an increase in the volume of the chambers.
