This study aimed to analyze the basic properties (chemical composition and physical and mechanical properties) of belangke bamboo () and its potential as a particleboard reinforcement material, aimed at increasing the mechanical properties of the boards. The chemical composition was determined by Fourier transform near infrared (NIR) analysis and X-ray diffraction (XRD) analysis. The physical and mechanical properties of bamboo were evaluated following the Japanese standard JIS A 5908 (2003) and the ISO 22157:2004 standard, respectively. The results showed that this bamboo had average lignin, holocellulose, and alpha-cellulose content of 29.78%, 65.13%, and 41.48%, respectively, with a degree of crystallinity of 33.54%. The physical properties of bamboo, including specific gravity, inner and outer diameter shrinkage, and linear shrinkage, were 0.59%, 2.18%, 2.26%, and 0.18%, respectively. Meanwhile, bamboo's mechanical properties, including compressive strength, shear strength, and tensile strength, were 42.19 MPa, 7.63 MPa, and 163.8 MPa, respectively. Markedly, the addition of belangke bamboo strands as a reinforcing material (surface coating) in particleboards significantly improved the mechanical properties of the boards, increasing the modulus of elasticity (MOE) and bending strength (MOR) values of the fabricated composites by 16 and 3 times.
本研究旨在分析版纳甜龙竹（）的基本特性（化学成分以及物理和力学性能）及其作为刨花板增强材料的潜力，旨在提高板材的力学性能。化学成分通过傅里叶变换近红外（NIR）分析和X射线衍射（XRD）分析来确定。竹子的物理和力学性能分别按照日本标准JIS A 5908（2003）和ISO 22157:2004标准进行评估。结果表明，这种竹子的木质素、全纤维素和α-纤维素平均含量分别为29.78%、65.13%和41.48%，结晶度为33.54%。竹子的物理性能，包括比重、内外径收缩率和线收缩率，分别为0.59%、2.18%、2.26%和0.18%。同时，竹子的力学性能，包括抗压强度、抗剪强度和抗拉强度，分别为42.19兆帕、7.63兆帕和163.8兆帕。值得注意的是，在刨花板中添加版纳甜龙竹束作为增强材料（表面涂层）显著提高了板材的力学性能，使制成的复合材料的弹性模量（MOE）和抗弯强度（MOR）值分别提高了16倍和3倍。
