中文摘要 因我国天然林禁伐，人工速生林木材和竹材成为当前木材加工利用的主要原材料，但人工速生林材质不及天然林材质，且竹材也存在截面尺寸小、用胶量大、原料利用率低等缺点。展平竹与木材正交胶合材（CLBT）由展平竹材和人工林锯材层板正交层叠制成，充分发挥了竹材优异力学性能与木材易加工等优势，既保留竹子和木材的天然纹理与结构特性，又克服了人工速生林材性的不足，实现了人工林资源的高附加值利用，是符合我国装配式建筑发展趋势的竹木质工程材产品。文中阐述了CLBT工艺技术、材料优势、构件性能及其影响因素等研究现状，介绍CLBT在我国多高层板式结构建筑中的应用前景，并提出今后研究方向。

英文摘要 Because of China's ban on natural forest logging, the timber from fast-growing planted forests and bamboo are now the primary raw materials for current deep processing industry. However, the timber from fast-growing planted forest is not as good as the timber produced from natural forests in quality, and bamboo also has the problems such as small cross-sectional dimensions, large application of glue and low material utilization rate. Cross-Laminated flattened bamboo and timber (CLBT) are made of flattened bamboo and sawed timber laminated by orthogonal stacking, which gives full play to the excellent mechanical properties of bamboo and the easy processing performance of wood. CLBT not only keeps the advantages of bamboo and wood in the natural texture and structural characteristics, but also overcomes the shortcoming of material properties of timber from fast-growing planted forests for higher value-added utilization. It is a bamboo and wood engineered product that conforms to the development trend of prefabricated buildings in China. This paper describes the research on CLBT technology, material advantages and component performance as well as its influencing factors. The application prospect of CLBT in China’s multi-high-rise slab structure building is introduced, and the future research direction of CLBT is also proposed.
