The objective of this work is the study of the diversification of cork oak stands, managed to produce cork oak wood flooring.
The wood of Quercus suber L. has high density values (0,86 gcm-3 to 0,98 gcm-3) with a small ring variation (both axial and radial) as well as between trees. The wood of Q. faginea L., was studied for comparison proposes, has an average density value of 0.85 g cm-3.
Cork oak presented an average growth of 3,9 mm/year which, together with its high density, makes it an interesting species when it comes to carbon storage.
Modeling and simulation techniques were used regarding the industrial transformation of the cork oak stems. The maximization of the production yields was achieved with small logs and components with short dimensions (parquet and components for multilayer composites).
Relevant properties for flooring applications (hardness, wear and dimensional stability) were assessed. Results indicate that the cork oak wood is suitable for flooring applications with high traffic uses.
Conclusions show the technological feasibility of cork oak wood to flooring applications, and therefore a strong alternative to other oak and tropical species.
