What are the effects of resin aging on WPC armchair mechanical properties?

Resin aging significantly impacts the mechanical properties of Wood-Plastic Composite (WPC) armchairs, affecting their durability and performance over time. As the resin component degrades due to environmental factors like UV exposure, moisture, and temperature fluctuations, the armchair's structural integrity may weaken. Key mechanical properties such as tensile strength, flexural strength, and impact resistance can deteriorate, leading to reduced load-bearing capacity and increased brittleness.

Studies show that prolonged resin aging causes microcracks and interfacial debonding within the WPC matrix, further compromising its mechanical stability. To mitigate these effects, manufacturers often incorporate stabilizers and UV inhibitors during production. Understanding these aging mechanisms is crucial for designing longer-lasting WPC furniture. Regular maintenance and protective coatings can also extend the lifespan of WPC armchairs, ensuring they remain functional and aesthetically pleasing for years.
