In the “TERIS” project, the Fraunhofer institutes ICT, IGD, and IWM - led by the Fraunhofer Institute for Structural Durability and System Reliability LBF - have reached a decisive milestone. For the first time, the teams aim to generate, analyse, and predict tire wear in the laboratory in a standardized and practical manner. As part of this milestone, results are now available on reference abrasion, particle analysis, tribological models, AI-based surface analysis, a test bench concept, and methods for accelerated aging and VOC detection. The tire industry, testing services, and environmental agencies will in future benefit from reliable, rapid laboratory procedures for emissions assessment
The project “Technology Platform for Tire Abrasion and the Identification of Its Emissions in Road Traffic (TERIS)” is making significant strides in tire and rubber-compound development. With the first milestone achieved and the project reviewed, the first important step has been successfully completed. This was also confirmed by the advisory board, composed of industry experts, which typically oversees such projects.
New Standards for Laboratory Analysis and Prediction of Tire Wear
The combination of different collection and measurement methods enables precise analysis of both suspended and settling particle fractions. In parallel, tribological models were developed that shed light—both experimentally and theoretically—on the relationship between load parameters, material properties, surface structure, and particle formation. This enables real-world abrasion processes to be specifically replicated in the laboratory.
A test chamber specialized in accelerated aging enables preconditioning of samples in a targeted and reproducible manner under environmental stress, thereby also investigating the influence on abrasion behaviour.
A major advancement is the development of an optical detection system that uses artificial intelligence to precisely identify and classify surface structures. The approach has already been validated using substitute materials and will be applied to real rubber samples in the next phase.
The consortium has also designed a test bench concept that combines the generation of rubber abrasion under multiaxial loading, targeted particle detection, and the integration of optical sensors in a laboratory setup.
A combination of weathering and chemical analysis of volatile organic compounds (VOCs) generated by tire abrasion enables assessment of the environmental impact of particles.
The results provide the basis for an accelerated, practical, and well-founded evaluation of new rubber compounds in the laboratory. Tire manufacturers, testing services, and environmental agencies are thus provided with tools that enable them to specifically reduce emissions, evaluate new products more quickly, and meet the requirements of the Euro 7 standard.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
