Improvement of flexibility of wood-based composite

研制了一种可控制弯曲柔度的柔性木基材料。特别是丙烯酸酯压敏胶的使用，提高了柔性单板层积材的许用挠度。柔性单板层积材抗弯刚度和强度的实测值与剪切变形效应的多层组合理论计算值吻合较好。以木材碎料和聚乙烯片材为原料制备的木基复合材料具有较高的柔韧性。

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.
