What are the differences in thermal expansion between WPC and carbon fiber tree boxes?
When comparing WPC (Wood-Plastic Composite) and carbon fiber tree boxes, one of the critical differences lies in their thermal expansion properties. WPC, being a composite of wood fibers and plastic, tends to expand and contract more significantly with temperature changes due to its organic components. Carbon fiber, on the other hand, exhibits minimal thermal expansion because of its high stiffness and stable molecular structure. This makes carbon fiber tree boxes more dimensionally stable in varying climates, while WPC may require additional design considerations to accommodate expansion. Understanding these differences helps in selecting the right material for durability and performance in outdoor applications.
