Laboratory of wood quality and non-destructive testing

The accurate definition of measurable indicators of “wood quality” in different operational contexts is the main concern of the laboratory. Basic and applied research activities are devoted both to the improvement of existing test standards and to the development of new standards when needed.
The laboratory comprises five “measurements platforms”, i.e. sets of advanced measuring equipment modules, which can be flexibly arranged in order to build up a measurement system carefully tailored to the research task to be performed:
- Measurement platform for solid wood and sawn timber
- Measurement platform for veneers and wood surfaces
- Measurement platform for wood-based panels and acoustic boards
- Measurement platform for biomasses
- Environmental impact of wood

- Quality of wood and sawn timber
Research activity devoted to estimate the quality of wood. Applications on wood from local forests, measuring standing trees. disks from logs and from small clear specimens integrated in synthetic indexes, used to design maps describing the quality of wood in forests.

- Quality of veneers and quality of surfaces
Research activity carried out in international framework, by developing specific devices such as optical system based on lasers and imaging via digital cameras.

- Quality of tonewood panels
Acoustic measurements on timber for musical instruments and characterization of local tonewood.

- Characterization of wood for industrial uses (R&D for Enterprises)
Confidential activities for industrial clients. Some examples: surface finishing of furniture, strength on glued lines, shrinkage and swelling on wooden objects, etc. 

- Environmental impact of wood
Research activity on ecologic aspects of wooden products: Life Cycle Analysis, recyclability, Indoor Air Quality (formaldehyde, tVOC emissions, airborne particulate).
