Wood is not only the oldest utilized resource in human history but also nowadays one of the most trendsetting materials due to its excellent properties and eco-balance. However it demands further efforts to advance its performance in order to establish wood as a modern biomaterial with superior properties against alternative building materials. Intrinsic drawbacks such as low durability, shrinkage anisotropy, combustibility as well as natural variability limit the reliability of wood as a construction material. To overcome these limitations this project aims at improving wood cell walls by biomimetic approaches, nano(bio)technological techniques and modelling. In this vein wood with improved material performance should be made available for the utilization of wood as a building material and for interior works. The project aims at reducing the high shrinkage and the combustibility as well as increasing the low durability of wood by developing novel approaches to establish polymers in wood cell walls, in particular by transferring natural principles of heartwood formation. The challenge is to overcome the limited penetrability of the wood cell wall and develop impregnation routines that are relatively cheap and do not impair the mechanical properties of the wood material. The work will be complemented by modelling and numerical simulation activities. The aim is to develop nano-scale statistical models for the modified structures of the cell wall. Thereby it will be elucidated how nano-scale modifications change micro- and macromechanical properties, which is a prerequisite for designing advanced wood materials.
