| Abstract: | Strengthened bamboo/wood composite laminated veneer lumber (LVL) was manufactured using poplar (Populus nigra) veneer and bamboo curtains as raw materials, impregnated with modified water-soluble PF resin. The effects of the impregnating process, assembly patterns, and hot pressing parameters on properties of the bamboo/wood composite LVL were explored. The results showed that MOE and MOR of the composite LVL could meet or surpass the relevant requirements of JAS standards. They also exhibited rather desirable dimensional stability with TS 2.4%. Veneer thickness, PF resin concentration, as well as compression ratio, all had significant influences on MOE and MOR. Assembly patterns were found to have a major effect on MOR. Furthermore, there were complicated factors associated with TS of the composite. |
