摘要

A laminated bamboo sandwich panel with a grid core was developed, utilizing bamboo veneers for both surface and core layers. Four-point bending tests evaluated the effects of structural parameters—processing methods, grid count, and layer thickness—on ultimate load-carrying, deflection, strain, specific stiffness, and specific strength. The empirical results indicated that grid core processing significantly influences performance, with partition sandwich panels exhibiting 108.9% higher specific strength than interlocked sandwich panels. Increasing long grid numbers enhanced ultimate load-carrying capacity by 68.4% and specific strength by 41.7%, while short grids had minimal impact. Reducing lower layer thickness from 8 mm to 4 mm decreased specific strength by 24.2%, and reducing core thickness from 48 mm to 32 mm led to a 31.2% decline. Nonlinear load-deflection and load-strain behaviors were observed, and a simulation model successfully predicted structural performance. Compared to traditional materials, the laminated bamboo sandwich panel offers superior structural performance, reduced environmental impact, and cost reduction, making it highly suitable for construction applications such as flooring, wallboards, and bridge decks.
