Abstract: Bamboo scrimbers were prepared with thick and thin bamboo bundles as raw materials. Determinations were conducted on waterabsorption, thickness swelling rate, width swelling rate and horizontal shearing strength of scrimbers. The results showed that glue loading of thinbamboo bundles was 142.3% of thick ones 10 minutes after dipping glue. Water absorption, thickness swelling rate, and width swelling rate ofbamboo scrimber made by thin bundles was 114.0%, 131.1% and 115.0% of that by thick ones. The horizontal shear strength of the scrimber made bythick bamboo bundles was less than that by thin ones. The experiment resulted that thinner bundles had even gluing, denser pressed and betterproperties of scrimber.
