以去青留黄的竹片为原料，利用纤维原位可控分离技术，对竹片进行精细化疏解处理，再经浸胶、干燥后，采用热压法制备重组竹，并与普通的本色重组竹、低温炭化重组竹、高温炭化重组竹以及竹基纤维复合材料进行对比。结果表明：高温热处理是提高重组竹的耐水性能和尺寸稳定性的有效方法之一，其缺点是力学性能损失严重，静曲强度损失率达到45％；与高温炭化处理相比，精细疏解加工工艺简单，加工的重组竹力学性能基本不损失，且能更有效地改善重组竹的耐水性能和尺寸稳定性；与普通本色重组竹相比，采用精细化疏解竹束制备的重组竹，其吸水率降低75％，吸水厚度膨胀率降低67％，耐水性能和尺寸稳定性接近竹基纤维复合材料。

This study explored novel bamboo scrimber fabricated using fine fiber bundles and phenolic resins via hot?pressing process. The mechanical properties, water resistance and dimensional stability of novel bamboo scrimber were investigated, and the results were compared with commercial bamboo scrimber made from control and carbonized bamboo bundles and bamboo?based fiber composites. The results showed that fine fluffing treatment and high temperature thermal treatment showed good technological properties with improved water absorption and dimensional stability. However, the mechanical properties of bamboo scrimber were obviously decreased by high?temperature thermal treatment with 45% de?crease of MOR comparing with that of control. The fine fluffing treatment would improve bamboo scrimber dimensional stability while maintains its mechanical properties with 67% decrease of thickness swelling and 75% decrease of water absorption comparing with that of control. The water resistance and dimensional stability of bamboo scrimber made from bamboo bundles with fine fluffing was close to that of the bamboo?based fiber composites.
