Bamboo - wood container flooring, laminated structure, short span bending forceAbstract
This study evaluated the physical and mechanical properties of container flooring made from six different laminated structures, based on the following criteria: moisture content, density, delamination resistance, bending strength (MOR), modulus of elasticity (MOE) in both directions, and short - span bending force. The results showed that all samples met the moisture content requirement (< 10%) and the minimum density requirement (≥ 0.75 g/cm³) as specified in GB/T 19536 - 2015 and ISO 5942:2024. Samples made with flaked strips (KC1 - KC3) exhibited higher densities than those made with solid strips (KC4 - KC6). None of the samples showed signs of delamination after the boil - dry cycle, indicating stable bonding quality of the PF adhesive. In terms of mechanical performance, KC1 outperformed the others in all evaluated criteria, particularly in MOR, MOE, and short-span bending force. Only KC1 and KC5 met the required longitudinal bending strength according to GB/T 19536 - 2015 (≥ 85 MPa), while all six samples satisfied the transverse bending strength requirement (≥ 35 MPa). Although all samples met the short - span bending force requirement of GB/T 19536 - 2015, only five samples complied with ISO 5942:2024, as KC2 failed to meet the minimum required force
