Abstract
The linear vibration–friction welding offers several advantages compared to traditional mechanical fasteners or gluing. This study examines the possibility of applying mechanically-induced vibration welding to the joining procedure of a wood–bamboo sandwich-laminated composite. The result shows that average tensile strength values of the composites can meet the requirements of the furniture industry and even for wood construction. The X-ray microdensitometry analyses indicated an increase in density of the interfacial material between the wood substrate and the bamboo substrate. Furthermore the peak of the density profile between wood and bamboo outer layer is lower than that between wood and bamboo inner layer. This paper proves that the sandwich wood–bamboo welding lumber can be efficiently fabricated by linear vibration welding without any adhesive.
