The woodworking industry is notorious for its use of wood, despite the availability of laminates and other sub-materials. In the marine industry, it is used in the construction of boats, yachts, and other marine structures. In this study, tensile properties of coniferous species were examined as a function of salty water exposure for different periods of time. In coniferous woods such as pine, larch, and spruce, wood strength is determined by its ability to undergo tension and compression over time. Different mechanical strengths of wood soaked in water with a salinity of 7‰ were determined. According to the data, the salinity value corresponds to the average salinity on the Polish Baltic coast. As a result of the experiments, it can be concluded that the applied medium directly affects the species and structure of the wood. The parameters of wood are affected differently by soaking depending on its species. The tensile strength of pine was enhanced after incubation in seawater. By soaking other specimens in saltwater for a certain period of time, the study demonstrated different strength parameters. Wood exposed to salty water was compared to native wood in this study to determine its tensile properties. In conclusion, soaking wood in a certain medium significantly alters its mechanical properties. Analysis showed that all samples had an average strength between 5.4MPa and 102.04MPa. There was a slight difference in strength results for each wood species over time despite subsequent treatment cycles.

Zbadano właściwości rozciągające gatunków drzew iglastych w funkcji ekspozycji na słoną wodę przez różne okresy czasu. Określono różne wytrzymałości mechaniczne drewna nasączonego wodą o zasoleniu 7‰, które odpowiadało średniemu zasoleniu na polskim wybrzeżu Bałtyku. Stwierdzono, że zastosowane medium wpływa bezpośrednio na gatunek i strukturę drewna. Nasączanie wpływa w różny sposób na parametry drewna w zależności od jego gatunku. Wytrzymałość na rozciąganie sosny została zwiększona po inkubacji w wodzie morskiej. W badaniach wykazano odmienne parametry wytrzymałościowe, mocząc różne próbki w słonej wodzie przez pewien czas. Drewno wystawione na działanie słonej wody porównano z drewnem naturalnym, aby określić jego właściwości rozciągające. Namoczenie drewna w określonym medium znacząco zmienia jego właściwości mechaniczne. Analiza wykazała, że wszystkie próbki miały średnią wytrzymałość 5,4–102,04 MPa. Zaobserwowano niewielką różnicę w wynikach wytrzymałości dla każdego gatunku drewna w czasie, pomimo kolejnych cykli obróbki.
