摘　　要：单板厚度是影响单板层积材 (英文缩写 L VL )强度性能的主要因素之一。在同样的工艺条件下 ,单板越厚 ,L VL的剪断强度越低、剥离率越高。冷压胶合制造非结构单板层积材时 ,建议采用 4 mm厚的单板。The thickness of veneer is the main factor that affects the strength of laminated veneer lumber(LVL). At the same processing condition,the thicker the veneer, the lower the shear strength and the higher the split rate.It's recommended that 4 mm thick veneer is used when non-structural LVL is made through cold press menthod.

关 键 词：单板厚度 单板层积材 强度性能 冷压胶合法
