Abstract: A scientific and reasoned bamboowood composite panel was designed by applying the theory of laminated panel in composite mechanics.Laminated bamboowood composite lumber was formed 3 layers of masson pine boards with two layers of highdensity bamboo curtain boards that are glued in a press under high pressure in advance on top and bottom surfaces.It is a new engineering material with excellent physical and mechanical properties and has been used as rail flat wagon flooring successfully.
