Guadua chacoensis in Bolivia : - an investigation of mechanical properties of a bamboo species

Abstract: This Master thesis has been performed at CTD- the Centre for Wood Technology and Design at the University of Linköping and has been carried out in Santa Cruz de la Sierra in Bolivia. The objective of this thesis is to study the mechanical properties and uses of Guadua chacoensis, a bamboo native to Bolivia. Throughout history, bamboo has been used in many countries for a variety of purposes. In Asia bamboo is an important raw-material for buildings and furniture. It is also used for making paper and for land rehabilitation and fuel. In South America many countries, among them Bolivia, have great potential to use bamboo in the same way. One of the key ideas with this Master thesis is to make a contribution to support the Bolivian economy and welfare by elucidate this, hitherto undeveloped, natural resource. This thesis is a Minor field study partly financed by Sida- the Swedish International Development Cooperation Agency. During the field study theoretical studies were made, collecting local and international information about bamboo and Guadua chacoensis in particular. Laboratory tests were prepared and conducted at UPSA- the Private University of Santa Cruz de la Sierra and several localities of the plant were visited. Through tensile-, bending- and hardness test it is found that Guadua chacoensis is a flexible, medium soft material and is comparable with European oak when it comes to the tensile strength. This leads to the conclusion that this bamboo species, among other fields of applications, can be used for constructions, like houses and bridges, and furniture manufacturing.
