Abstract

This doctoral thesis aims to develop a new industrialized reinforced timber product using local, fast-growing and low performance wood, or low quality, which is currently rejected for structural use. Current social requirements for sustainable and energy efficient buildings in European Directive 2018/844/EU position timber as one of the construction materials with the greatest growing potential in the future. In Europe today, traditional structural timber species are grown in well managed forests, but their harvesting capacity is conditioned by the growth times of each species and their limited surface. Therefore, to respond to the growing demand for timber in a sustainable way over time, it is necessary to introduce new fast-growing wood species into the timber industry and, in addition, to optimize the resources of traditional species. The low mechanical performance of fast-growing woods, and the negative influence of its peculiarities in the rejection timber, currently limit its intensive application to structural uses. The manufacture of industrialized timber products with Fiber Rein -forced Polymer (FRP). introduced in the glue-line aims to increase their mechanical performance, focusing on improving stiffness, to allow for their introduction in the construction of building structures. In this research, two wood species have been assessed: poplar (Populus x euroamericana I-214) and maritime pine (Pinus pinaster Ait.), grown extensively throughout Castilla y León and cultivated in intensive plantations in riparian zones (poplar) or in reforestations of arid lands (ma- ritime pine). From a social point of view, a change of use of these species and the manufacture involved may generate neweconomic resources, facilitating the creation of "green" employment and the establishment of population in rural areas.
