Creación de prototipos con fibra de lechuguín para su posible uso como material aislante térmico en la construcción

Abstract

At present the industry of the construction is the responsible of 23% of global contamination, given that many materials are derived of non-renewable sources, therefore it is necessary to create a sustainable building model that has the least impact on the environment. For that reason, this research is carried out which seeks to determine the characteristics and potentialities of the petiole fibre of Lechuguín (Eicchornia crassipes) for use as thermal insulation material. The focus of this research in exploratory quantitative, starting with a bibliographic review of the species, succeeded by laboratory tests in this case of compression, moisture absorption, density and thermal conductivity, using prototypes of cubic form 4x4cm, constructed with different sizes of crushed fiber, combined with polymeric resin and a pressing pressure of 4.8kg/cm². As result of the testh realiced, it was determinated that the lechuguin fibre manifest good thermal insulation characteristics, obtaining values between 0,049 y 0,081 W/m°C, and an average low of 0,251. Additionally, it added recommendations for the treatment of the species during of drying, as well as the potentialities in base to the test results and the review literature.
