Hybrid foams and lightweight constructions

A special process will make it possible to improve the mechanical, thermal and acoustic properties of foams in the future. This will be of particular benefit to lightweight construction.

Mother nature is a smart builder. The cell structure of bones and honeycombs, for example, is particularly resilient and gets by with extremely little material. The process by which these lightweight structures form is just as suitable for foaming metals, plastics and ceramics.

These foams have specific properties depending on the material they are made of. While plastic foams are light and flexible but cannot withstand high temperatures, metal foams are extremely tough but are heavy and not very flexible. Ceramic foams are quite stiff and can resist even very high temperatures, but are rather difficult to shape.

In the automotive and aerospace industries, it would be more effective and resource-saving to combine the flexibility of plastic with the resilience of metal to create a material with entirely new properties. This is exactly what the Fraunhofer researchers are striving to do by developing hybrid foams. What is special about these materials is that they have the potential to acquire completely new characteristics, while at the same time eliminating the specific weaknesses of each constituent, such as the heavy weight of the metal foam.

The efficiency of the novel materials is to be demonstrated in three test applications: One is to increase the sound insulation in a combustion engine, another is to improve the energy absorption in a crash box, and the third is to manufacture lightweight, high-strength components. A research group comprising the Fraunhofer Institutes for Chemical Technology ICT, Manufacturing Engineering and Applied Materials Research IFAM, Ceramic Technologies and Systems IKTS, Silicate Research ISC and Mechanics of Materials IWM has taken up the challenge of developing the multifunctional hybrid foams.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
