Fortalecimiento de la Cadena Productiva del Bambú Guadua con la Producción de Laminados Strengthening of the Bamboo Guadua Chain with Production of Laminates
-2 (resorcinol), 1,7 kg∙cm -2 (PVA) y 3,7 kg∙cm -2 MPa (cola); a compresion paralela 419 kg∙cm-2 (melamina), 424 kg∙cm-2 (resorcinol), 506 kg∙cm-2 (PVA) y 375 kg∙cm -2 (cola) y a compresion perpendicular 216 kg∙cm -2 (melamina), 206 kg∙cm -2 (resorcinol), 245 kg∙cm -2 (PVA) y 240 kg∙cm -2 (cola). Se observo que en general las probetas elaboradas con melamina y resorcinol presentaron un mejor comportamiento mecanico.

In this paper, the process of cutting the bamboo guadua, the production of slats, the manufacture of laminates and results of tests in slats and laminated samples made with four types of glue: -melamine, resorcinol, polyvinyl acetate and natural glue are presented. It was found that the longitudinal shrinkage of the bamboo guadua slats is relatively low and the relationship between the tangential and radial shrinkage was close to one showing the feasibility of using bamboo for laminated processes. The following average values of resistance were found: for parallel shear 47 kg∙cm -2 (melamine), 51 kg∙cm -2 (resorcinol), 17 kg∙cm-2 (PVA) and 32 MPa kg∙cm-2 (kola); for perpendicular shear 50 kg∙cm -2 (melamine), 43 kg∙cm -2 (resorcinol), 49 kg∙cm -2
