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

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
