“…This is also supported by the findings of Koohbor and Kidane, who investigated the mechanical properties of discretely layered, graded foams. [6] Further evidence for our explanation is the fact that the sample breaks at the transition between the two density regions. Another reason why the sample tends to break at the transition region can be imperfections introduced during sample production when the gas pressure is changed to change the bubble size.…”

“…[1,2] The big advantage of graded foams is the improved mechanical stability of the material under low energy impact, while still performing nearly as well as their uniform counterpart under high energy conditions. [3][4][5][6] Therefore, in technical applications, graded foams are widely used for safety components. Other potential applications for functionally graded foams are interfacial tissue engineering, [7][8][9] especially for bone implants, [10][11][12] (micro) filtration, [13][14][15] as well as construction.…”

“…Es wurden zwar bereits viele wissenschaftliche Arbeiten durchgeführt, um Kenntnisse darüber zu gewinnen, wie man die Struktur und damit die Eigenschaften porçser Polymere kontrollieren kann, noch fehlt allerdings eine systematische Studie dieses Problems.E sw urden Modellrechnungen zum Einfluss eines Porositätsgradienten [13,14] sowie der Porosität, der Porenorganisation und der Polydispersität [15] auf die mechanischen Eigenschaften porçser Polymere durchgeführt. Die verschiedenen Parameter,d ie wir kontrollieren müssen, um die Struktur maßgeschneidert einstellen zu kçnnen, sind in Abbildung 2z usammengefasst.…”

“…[14] Die laminierten Grenz-flächen führen jedoch zur Stresslokalisation, die ihrerseits Rissanfälligkeit und ein Ablçsen der Schichten zur Folge haben kann.
