Stress and Strength Analysis of Adhesively Bonded Bamboo and Hinoki Cypress Single-Strapped Joint Under Tensile Loads

Abstract

In this study, we explored the combined use of Bamboo, which has high tensile strength, and waste wood produced during Hinoki (Chamaecyparis obtusa Endl.) thinning, which has not previously been utilized effectively, in the production of high- quality plywood board. In our method, a single Bamboo plate was glued to one side of the two abutting Hinoki plates to create a single-strapped joint. The tensile strength and its dependence on the dimensions of the Bamboo plate were investigated. To identify the origin of joint separation, the adhesive layer stress distributions were calculated using the finite-element method.
