Improvement of flexibility of wood-based composite

研制了一种可控制弯曲柔性程度的柔性木基材料。特别是丙烯酸压敏胶的使用，增加了柔性层压单板木材的允许挠度。采用多层堆积理论计算了柔性层板的抗弯刚度和抗弯强度，结果与计算值吻合较好。由木颗粒和聚乙烯片材制成的木质复合材料具有很高的柔韧性。

A flexible wood-based material that can control the degree of flexibility of bending was developed. An allowable deflection of the flexible laminated veneer lumber (LVL) was increased by the use of acrylic pressure-sensitive adhesive, especially. Measured values of bending stiffness and strength of the flexible LVL gave close agreement with calculated values by using a multi-layer built-up theory for shear deformation effect. A wood-based composite that prepared from wood particle and polyethylene sheets had high flexibility.
