Abstract: Wood fiber tress which is the cell of scrimber and bamboo tress which is the cell of bamboo scrimber are made into bamboo and wood hybrid scrimber in three different hybrid structure types with different hydrid ratio of bamboo tress to wood tress according to the principle of hybrid fiber composite material.The results showed that specific MOE of bamboo and wood hybrid scrimber is lightly higher than that of scrimber made by poplar,but the specific MOR of bamboo and wood hybrid scrimber is sharply higher than that of the scrimber.The bending properties of sandwich structure with bamboo as surface and back is the best among three structure types,while that of homogeneous mixing structure is the worst.The bending properties of bamboo and wood composite scrimber is increased by the ratio of bamboo tress.The specific MOE and specific MOR of bamboo scrimber is more 50% and 120% than those of wood scrimber respectively.
