Manufacturing Process and Performance Experiment of Natural Arc-Shaped Bamboo Laminated Lumber
Abstract
Natural arc-shaped bamboo laminated lumber (ABLL) represents an eco-friendly advanced material. This study introduces an innovative preparation method and manufacturing process to enhance production efficiency and reduce costs. Full-scale processing experiments were conducted to evaluate the feasibility and performance of the innovative integrated fixed-arc and drying process. Bonding integrity was assessed through glue-line shear strength and soak-delamination resistance. The maximum dry glue-line shear strength and delamination length achieved were 8.19 MPa (>traditional value of 3.5 MPa) and 21.8 mm (<traditional value of 25 mm), respectively. Comparative analysis of material utilization of eight-layer natural arc-shaped bamboo laminated lumber demonstrated a rate of 77.9% (<traditional value of 60%). This optimized process significantly contributes to elevated production efficiency and material yield in natural arc-shaped laminated lumber manufacturing.
