What are the effects of prolonged UV exposure on rattan’s tensile strength?
Prolonged UV exposure significantly impacts rattan’s tensile strength, causing gradual degradation of its structural integrity. Ultraviolet rays break down the natural fibers in rattan, leading to brittleness, reduced elasticity, and eventual cracking. Studies show that extended sunlight exposure can decrease rattan’s tensile strength by up to 40%, making it less durable for outdoor furniture applications. To mitigate these effects, protective coatings or UV-resistant treatments are often recommended. Understanding these changes helps in selecting the right materials for long-lasting outdoor use.
