A description of the microstructure and the micromechanical properties of spruce wood

Popis výsledku v původním jazyce

Knowledge about the microstructure and the morphology of individual phases within wood tissues is essential for numerous applications in materials engineering and in the construction industry. The purpose of the work presented here is to monitor the distribution of elastic stiffness within the tissues of individual cells using state-of-art equipment and exploiting emerging methods, such as modulus mapping, to investigate the morphology of the individual phases. Quasi-static nanoindentation was carried out on cell walls of spruce earlywood and latewood tracheids to obtain values for the indentation modulus, which is closely related to the Young modulus of the material. Dynamic modulus mapping, also known as nanoDMA, was utilized to obtain a map of the elastic moduli over the entire tracheid cross-section. In particular, it was found that the indentation stiffness of the cells walls ranges between 10.5 GPa for of earlywood tracheids and 12.5 GPa for latewood tracheids. The difference bet
