US scientists have developed a ceramic airgel that is extremely light, durable and heat resistant. It could be used, for example, for the insulating tiles of spacecraft.

Sample of the new airgel

99% of the ceramic airgel consists of air. It is very flexible and heat resistant.

When a Space Shuttle enters the Earth’s atmosphere from a space flight, extreme heat develops on the outer shell. Super insulators serve as a barrier in such situations to protect (more…)

Materials with better mechanical properties without significant weight gain. This is promised by a special manufacturing process, which was developed in the framework of the EU research project CoMUnion.

Lightweight components are becoming increasingly important. This is especially true for the transport industry. Whether it’s vehicle manufacturing, shipbuilding (more…)

Researchers at the University of the Saarland have succeeded in producing a metal foam that is extremely light and airy and at the same time withstands high loads.

The principle of metal foams is not new. These porous materials are made of metals and look like a sponge. The airy construction makes them very light. However, producing (more…)

Melbourne researchers have a bizarre result: they may have found a way to make a medical replacement for cartilage from worn-out denim pants. This is completely vegetable.

A Sino-US team has for the first time succeeded in producing plates from graphene without the material losing its superior properties. It could become a competitor for carbon fiber reinforced plastics (CFRP).

Fraunhofer researchers have apparently made the impossible: Depending on the type of curing, a new adhesive has different properties. He can be used in the construction of vehicles and aircraft, because he puts away vibrations easily. But even orthopedists can use it to heal postural damage.

The steel giants Thyssenkrupp and Tata Steel have been negotiating for more than a year, and now there is an agreement: The companies found a joint venture, and 2000 employees have to go.

The industrial group Thyssenkrupp will merge its European steel division with that of its Indian competitor Tata Steel. The companies agreed on Wednesday.

Form a new link for a metal chain, build a towing strap, or make a snug rail for the broken finger in the wild: Braeön makes it possible , The plastic band can be heated, shaped and should be as hard as steel when cooling down.

According to the manufacturer, one layer of the Braeön plastic strap can withstand a pull of almost 1,000 kg.

If the heavy train accident in Eschede in 1998, when an ICE derailed because of a broken wheel tire, would not have happened with this new steel? Engineers have developed a steel structure based on the model of bone, which is significantly better protected against cracks and fatigue fractures. Expectations are high.

Steelmaking at Salzgitter: An international research team has now developed a steel alloy that is based on the structure of the human bone. As a result, the engineers want to prevent fatigue fractures. A broken wheel tire led to the Eschede train disaster.
