  • Automotive Testing / 2019

    Optimized component testing and validation

    Press release / 16.5.2019

    Numerical simulations have massively accelerated product development over the past few decades. A variety of scenarios can be tested in a short time and the number of necessary prototypes has been steadily reduced. Nevertheless, physical tests are widespread and will not lose significance over the next few decades. Numerical models must be validated and approval testing must be carried out. Depending on the modeling complexity, the physical test can also be more cost-efficient. In the recently completed project “Digitization in Testing Technology”, scientists from the Fraunhofer Institute for Structural Durability and System Reliability LBF addressed the question of how physical testing can benefit from methods from the numerical world. What is the optimal combination of real and virtual world? Tunable test rig components and a mechanical hardware-in-the-loop approach have been developed. They make it possible for mechanical parameters such as stiffness rubber mount properties and structural dynamic effects to be set quickly and without modifications to the test rig. This facilitates rapid parameter variations to the test rig and further provides a new, energy-efficient interface between numerical real-time simulation and testing bench. The Fraunhofer LBF will present the results at the Automotive Testing Expo in Stuttgart from May 21-23, 2019 in hall 8, booth 8052.

  • More range for electric vehicles / 2019

    Functionalized thermoplastic sandwich components within minutes

    Press release / 14.2.2019

    In times of impending bans for diesel and generally internal combustion engine (ICE) vehicles, battery electric vehicles (BEVs) are becoming increasingly interesting for buyers, especially in urban environments. Boosting battery capacities enable longer travels, however driving range of EVs varies especially at low ambient temperatures. Within the EU project “OPTEMUS” (Optimized Energy Management and Use), a large number of efficiency-enhancing technologies were therefore developed and holistically linked, in particular to reduce the range variation of a Fiat 500e EV. This includes a traction battery with thermal storage capacity, which the Fraunhofer Institute for Structural Durability and System Reliability LBF has developed with partners. The focus is on a novel sandwich battery housing made of continuous fibre reinforced thermoplastics (CFRTP), which helps to insulate stored heat in the traction battery for preconditioning. Fraunhofer LBF will present its research results from 12 to 14 March 2019 at the JEC trade fair in Paris at the Hessen joint exhibition in Hall 5, booth G71.

    The use of composite materials for ground transportation will be in the spotlight at an upcoming JEC event, “The Future of Composites in Transportation”, on June 27 and 28, 2018 in Chicago. For the Fraunhofer Institute for Laser Technology ILT in Aachen, a highlight at the event will be receiving the “Future of Composites in Transportation 2018 Innovation Award” in the category “Passenger Cars”. This accolade honors the development of a hybrid roof bow in collaboration with Weber Fibertech GmbH, Werkzeugbau Siegfried Hofmann GmbH, Fraunhofer Institute for Structural Durability and System Reliability LBF, SCANLAB GmbH and the BMW Group. In short, this component demonstrates successful implementation of laser processes in lightweight production.

    Smart connections: Intelligent sensors monitor and optimize industrial processes 4.0

    Press release / 22.6.2018

    Already today modern production systems can communicate with their surroundings and manage themselves. Industry 4.0 is on the rise and cyber-physical systems (CPS) are the essential components of this development. Intelligent sensors for monitoring and controlling production processes ensure that connected work processes can run reliably. Scientists at Fraunhofer LBF have used these technologies as part of the "ImProcess4.0" project and developed an intelligent sensor node-based monitoring and optimization system for production lines using twin-screw extruders. With this sensor system unfavorable operating conditions or fluctuations in material properties can be detected, thus minimizing the occurrence of faulty batches or machine failures. It opens chances for predicted maintenance in production processes and thus stand still times will be reduced.

    Upcycling of PET Bottles: New Ideas for Resource Cycles in Germany

    Press release / 21.6.2018

    The new research project, UpcyclePET, is developing an innovative process for high quality cycle utilization of polyethylene terephthalate (PET). This research project enables the recovery of PET waste from plastic bottles to be used in high-grade industrial applications, and it targets to reduce the use of new polyamide-based plastic parts. The project team consists of the company EASICOMP GmbH, the Fraunhofer Institute for Structural Durability and System Reliability LBF, and the Institute for Applied Ecology (Öko-Institut e.V.).

    Fraunhofer LBF at the Compounding World Expo 2018: Plastic Recycling and Intelligent Monitoring of Industrial Processes 4.0

    Press release / 30.5.2018

    Plastics are conquering the earth - unfortunately not always to the earth’s advantage, as indicated by the increasing reports on plastic waste. Two studies by the Fraunhofer Institute for Structural Durability and System Reliability LBF, on the other hand, demonstrate that upcycling of PET bottles and the recycling of flame-retardant plastics are worthwhile both for economic reasons and for protecting the environment. Further details on these studies will be presented at the Compounding World Expo 2018 in Essen, from June 27 to June 28, at booth 707. Another main focus will be on new procedures in process technology, under the keyword Industry 4.0. A monitoring system that is based on intelligent sensor nodes, for example for a twin-screw extruder, ensures that networked work processes run reliably. With another patented procedure, the corrosiveness of plastic melts can be determined quickly, which also helps to prevent downtime in the future.

    Come together: teamwork achieves optimum composite design

    Presse release / 15.2.2018

    At the JEC World Composite Show in Paris this March, the Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt and the Fraunhofer Institute for Laser Technology ILT in Aachen will be demonstrating how well-coordinated collaboration makes it possible to optimize a hybrid automotive component for series production: Together with their industrial partners, these Fraunhofer institutes have developed a multi-material roof bow as an exhibition piece, which the researchers are looking to present for the first time at a joint booth hosted by the Aachen Center for Integrative Lightweight Production AZL, Hall 5/C55.

  • Nondenstructive testing / 2018

    Brilliant perspective: Computer tomography analyzes damage to raw materials under load

    Presse release / 25.1.2018

    The ability to test various materials without destroying them is essential in many areas of commerce and industry. The Fraunhofer Institute for Structural Durability and System Reliability LBF has now developed a new method that for the first time combines the mechanical testing of a component under realistic loads with a radiographic examination. The method is used to characterize materials, and it makes it easier to assess inclusions or damage to raw material with regard to their influence on the durability and service life. In so doing, Fraunhofer LBF provides materials designers and manufacturers as well as scientists with information for better understanding of material behavior and material characterization.

  • Bringing the road into the laboratory / 2017

    Users discuss biaxial fatigue-testing for car and truck wheels

    Presse Release / 16.11.2017

    In the past, service life tests for vehicles or individual components required test drives on the road lasting several days. Today, thanks to cutting-edge testing facilities, a few hours in the laboratory is enough. The Fraunhofer Institute for Structural Durability and System Reliability LBF has specialized in recent years in the area of wheel testing and approval. Thanks to its diverse development and testing activities the institute has carved out a position for itself as a technology leader. The UC 13 – Users Conference on Biaxial Fatigue Testing for Wheels and Wheel Hubs held on November 8 in Darmstadt provided an opportunity to find out more about the latest developments in this area of technology and to swap experiences. Around 50 scientists and users from Europe, Asia and the USA gathered in Fraunhofer LBF for the conference, the 13th to be held.
