Specific elastic modulus of bamboo fiber paper was evaluated when the shellac was added into the paper during the paper making process. For the fabrication of the paper, bamboo fibers were treated with the alkali solution after extraction. The bamboo paper was fabricated with a heat pressing technique using the wet bamboo fibers sheet obtained by the filtration. Particle type of the shellac was used as the binder material of the paper. To compare the test results, lacquer type of the shellac was also applied in which ethanol was contained in the process.When the particle type of shellac was added into the paper, the specific elastic modulus of the paper was improved. It was shown that effective weight content of the shellac was about 20% to obtain the improvement and steady properties of visco-elastic behaviors. The improvement of the specific elastic modulus was explained with the increase of contact points between fibers in the bamboo fiber paper, when particles of shellac were added into the paper.
