What role does fiber length and aspect ratio play in the mechanical performance of WPC tree boxes?
Fiber length and aspect ratio are critical factors influencing the mechanical performance of Wood-Plastic Composite (WPC) tree boxes. Longer fibers and higher aspect ratios generally enhance tensile and flexural strength by improving load transfer within the composite matrix. However, excessive fiber length can lead to processing challenges, while optimal ratios ensure balanced durability and workability. WPC tree boxes with well-engineered fiber parameters exhibit superior resistance to urban environmental stresses, making them ideal for sustainable landscaping. Understanding these relationships helps manufacturers optimize material formulations for long-term performance.
