The Federal Institute for Materials Research and Testing (BAM) demonstrates its proficiency in composite materials research and testing using methods which have been specifically developed for this material class at the JEC exhibition (Journals and Exhibitions on Composites) in Paris from 3 to 5 April 2007.
In certain parts of the aircraft industry a new and more efficient method has been developed in close cooperation between the certification authorities and BAM. This method does not require expensive and lengthy service life tests on original components. Instead, it measures the service loading fatigue of the structure using representative components.
The new method makes the rapid certification of aeroplanes possible whilst simultaneously maintaining high quality and safety standards. It is intended to implement this method in various sectors of industry to achieve a wide use of composite materials.
The beneficial characteristics specific to fibre reinforced composites, in particular, high strength and relatively low weight, increasingly replace steel and aluminium alloys among construction materials. Fibre composite materials come together only at the manufacturing process of a component as opposed to the prefabrication needed for metallic construction components. Therefore, to guarantee the service loading fatigue of a primary structure, the processing instructions must be precisely and accurately followed. Crucially, the limiting stress of composite materials and the parameters used to certify the module depend on the individual manufacturing process. Therefore, to test the production quality of fibre composites at the requisite time, BAM has developed special non-destructive test methods such as an ultrasonic procedure, which can monitor the hardening of polymer matrix systems directly during the manufacturing process.Information: Dr. Volker Trappe

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
