Abstract
The influence of artificial weathering on abrasion resistance of selected wood species from South America The artificial weathering method consisting of alternating soaking wood in water, drying at a temperature of 70 °C and UV radiation exposure was used to determine the influence of weathering on resistance to abrasion of garapa (Apuleia leiocarpa (Vog.) Macbride), cumaru (Dipteryx odorata (Aubl.) Wild.) and tatajuba (Bagassa guianensis Aubl.). Selected wood species were of similar structure, density and hardness. The results of artificial weathering are changes in the abrasion resistance. With the progressive artificial weathering abrasion resistance of wood changed gradually. In case of tatajuba and garapa wood resistance to abrasion was similarly. In case of garapa wood, the widest range of changes after weathering process was observed. It was found that not only wood density determines wood abrasive resistance, but an important factor is wood structure, mainly arrangement of wood fibers.
