Effect of Resin Impregnation Rate on Physical and Mechanical Properties of Laminated Bamboo Fibrillated-Veneer Lumber

TLDR: In this article, the effect of resin impregnation rate on mechanical performance and water resistance was discussed, and it was shown that increasing specimen resin content from 7% to 13% had a negative impact on the average modulus of rupture (MOR) and tensile strength, and a positive influence on the shear strength and water resistant.

Abstract: The authors developed a new technology for making laminated fibrillated-veneer lumber.They designed an experiment using bamboo(Bambusa distegia) to optimize the processing parameters.The effect of resin impregnation rate on mechanical performance and water resistance was discussed.The results showed that increasing specimen resin content from 7% to 13%,had a negative impact on the average modulus of rupture(MOR) and tensile strength,and a positive influence on the shear strength and water resistance.However,the increase in resin content didn't affect the modulus of elasticity(MOE) or compression strength.The authors suggested that the panel's mechanical performance and water resistance could be predicted by controlling the resin impregnation level to meet different application demands.
