竹材竹材bamboo竹类木质化茎秆部分。有时泛指竹的茎、枝和地下茎的木质化部分。竹材的利用有原竹利用和加工利用两类。原竹利用时是把大竹用作建筑材料，运输竹筏，输液管道；中、小竹材制作文具、乐器、农具、竹编等。加工利用有多种用途，如竹材层压板可制造机械耐磨零件等；竹木复合板曾制成第一架竹材单翼高级教练机；竹材人造板可作工程材料。此外竹黄还可制成多种工艺美术品。竹材也是造纸、制纤维板和醋酸纤维、硝化纤维的重要原料。竹炭表面硬度高于木炭，可用于冶炼工业和制取活性炭。竹秆分节，两节之间为节间（见竹）。节间的秆壁横切面自外向内是：表皮、皮下层、皮层、基本薄壁组织（其中有维管束）和髓环。节的维管束向外或向内稍现弯曲，也有进入节隔盘曲复出的。节隔的维管束外缘密，中央疏，直径及方向无定；分成许多细枝，迂回交织成网状，是竹液横向流动的主要通道。节隔的基本薄壁组织的细胞加厚变硬。竹秆横切面构造示意图竹材的密度因竹龄（成熟的密度较大）、部位（梢段或秆壁外缘密度较大）和竹种而异，平均约0.64克/厘米3。竹材的干缩率低于木材，弦向干缩率最大，径向次之，纵向最小；干燥时失水快而不匀，容易径裂；气干竹材吸水性强。顺纹抗拉强度较高，平均约为木材的2倍，单位重量的抗拉强度约为钢材的3～4倍，顺纹抗剪强度低于木材。强度从竹秆基部向上逐渐提高，并因竹种、年龄和立地条件而异。竹材的化学成分为：纤维素40％～60％，半纤维素14％～25％或更多，木质素16％～34％，有随年龄增长的趋势。提取物：冷水浸出2.5％～5％，热水浸出5％～12.5％，醇-乙醚浸出3.5％～5.5％，醇-苯浸出2％～9％，1％氢氧化钠浸出21％～31％。此外还有蛋白1.5％～6％，脂肪胶腊2％～4％，淀粉类2％～6％，还原糖约2％，氮0.21％～0.26％，灰分1％～3.5％。所含磷、钾等的总量逐年减少，而硅则有增加，积聚于硅质细胞，竹青中可达4.35％或更多。
