Functional polymer chains covalently bond to wood are able to provide wood a completely new set of characteristics. In order to control and design distribution and functionality of the introduced functional polymers, new characterization technologies are needed. Chemical-force microscopy was identified as key-methodology capable of monitoring a wide range of functional groups, their distribution at the required high resolution and function in gaseous as well as in liquid ambient.

Wood is also today one of the most important raw materials and materials. The processing of wood, however, has changed considerably - from farm or manual processing to ultra-modern industrial products. The knowledge about wood selection, storage, processing etc. has traditionally been passed on from generation to generation. Only in exceptional cases are there written records. Only in the 14th century did special crafts develop. But here, too, the oral tradition of knowledge prevailed. The existing publications often do not provide the necessary details to understand the progress of the work or to understand why a specific type of wood has been used for this purpose. The goal of the project is a complete documentation of selected woodworking techniques. This requires new concepts of rotation, which are developed jointly according to a strongly participatory approach of pupils and scientists. For example, end cameras, 360 ° video and VR content can be used to follow the work steps optimally. Each concept is discussed in advance with the artisans and the scientists (wood research, folklore, media technology). It has to be known before the film recordings, what the "key places" are and how to document them best. Crafted artisans will be able to imitate these techniques by means of the films. On the one hand, detailed video documentation is to be developed and, on the other hand, a modern dissemination is carried out in order to inspire people for the craft. These films must therefore be available online, be mobile and adaptable for young people. Only in this way is it possible to motivate young people for crafts in general and to enable low-threshold access. The students make an essential active contribution to the production and presentation.

Current and future strategic challenges in the automotive industry (i.e. fuel reduction, CO2-balance, self-driving cars, electro-mobility, small city cars and special vehicles) require innovative vehicle concepts. Novel materials, material combinations and composites are urgently needed. Wood provides high stiffness, strength, excellent damping, high resistance against fatigue and a very low density paired with low material costs. Properly applied, modern wood composites are competitive to metals and fibre-reinforced materials. Wood is an abundant, carbon-neutral and renewable resource; raw material costs are low, and especially in Europe high quality wood material is available. Decades of experience in aeronautical, nautical and even in automotive engineering provide abundant proof of wood and wood composites being a reliable construction and engineering material. Wood can broaden the material portfolio in automotive engineering and can help improving the CO2-balance at lower weight and lower costs. However, the application of wood and wood composites in automotive engineering requires precise and reliable material data, e.g. for a very first material selection and later in numerical crash simulations. Last year, a feasibility study (650.000 EUR budget) was performed, proving that wood and wood products can be sufficiently well simulated by means of finite element methods under static and dynamic loads and in crash situations. Components of a few selected car components showed that wood can compete and outperform the baseline products (made of aluminum and fibre inforced plastics) in terms of structural properties, weight and costs. Still, a more thorough and comprehensive understanding of wood as load-bearing and energy absorbing (crash and vibration) material in vehicle-design is needed. WoodCAR (Wood - Computer Aided Research) will establish the knowledge and the requisites for integrating wood in virtual engineering and the vehicle design process in general. WoodCAR will establish the needed knowledge base on the mechanical properties, the grading, the processing, the integration and the recycling of numerous wood species and wood composites in vehicle design. WoodCAR will evaluate and improve existing and develop advanced material models for use in computer aided engineering (CAE). Sate-of-the-art production, joining and bonding technologies will be reviewed, analyzed, evaluated and integrated in the virtual engineering process. Application cases, not only from the automotive sector, will be selected. Based on meticulous specification sheets, the application cases will be developed by applying the initial virtual engineering process. In continuous feedback-loops, the process will be refined such that it is applicable in an industrial development process. Eventually, demonstrators will be built and tested, proofing the reliability of the virtual engineering process. Using the experience and expertise gained with the development of selected application cases, WoodCAR will conclude its work with an ample ecologic and economic assessment of wood as loadbearing material in dynamically loaded structures. Beside technological aspects, quality assessment and economic (bio-economy concepts, life-cycle analysis) will be considered.
