Manufacture and Mechanical Properties of Glued Bamboo Laminates

Abstract

Moso bamboo (Phyllostachys pubescens Mazei ex H. de Lebaie), one of the most commonly used species in China, is a strong and stiff material. In this paper, the manufacturing process for glued bamboo laminate (GBL) is presented. The mechanical properties of GBL (compression strength, bending, tension, and shearing) were tested. Results indicated that the mechanical properties of GBL were significantly different for different grades of GBL, but that the performance of GBL was controllable. The edge butt joint greatly influenced the tensile performance, but the butt joint had little impact on the bending performance. In addition, the good mechanical performance of GBL is sufficient for engineering members, making it a potentially useful bamboo product for engineering.

Evaluation of physical and mechanical properties of particleboard made from Petung bamboo using sucrose-based adhesive

“…In recent years, bamboo has become a main substitute material for wood in construction, parquets, and laminations (Mahdavi et al 2012;Huang et al 2013;Chen et al 2014;Ni et al 2016). One potential type of bamboo for use in materials is petung bamboo, which is found in Indonesia.…”

Physical-mechanical properties of laminated bamboo panels

“…Density is a variable that influences the mechanical properties. Values of 95-126 MPa for modulus of rupture and 8,115-10,635 MPa for modulus of elasticity were found by Ni et al (2016), due to the variation of 0.6-0.9 g cm -3 in the density of GLB panels. In GLB panels, the modulus of rupture, modulus of elasticity and shear strength were dependent on the distribution and uniformity of the density (Chen et al 2014).…”

Review of creep modelling for predicting of long-term behavior of glued-laminated bamboo structures

“…The long-term deformation behavior of a material can be approximated by a linear viscoelastic theory. According to Hook's law, the constitutive equation of linear viscoelastic material is a function of time, written in matrix form in equation (1). The independent components matrix could be determined experimentally, by using uniaxial (compression, tension, shear) creep tests.…”

“…Glued-laminated bamboo has been widely used to substitute timber as a building material is a natural resource with many benefits. Because the gluedlaminated bamboo produced from bamboo the benefits including, for example, environmentally friendly, renewable and sustainable material, good mechanical properties and similar with timber [1][2][3]. Gluedlaminated bamboo is classified as a viscoelastic material because it exhibits properties that are common to both solid and liquid.…”
