English title:	UNIAXIAL FATIGUE STUDY OF A NATURAL-BASED BIO-COMPOSITE MATERIAL REINFORCED WITH FIQUE NATURAL FIBERS
Spanish title:	ESTUDIO DE LA FATIGA UNIAXIAL EN UN MATERIAL BIOCOMPUESTO REFORZADO CON FIBRAS NATURALES DE FIQUE EN UNA MATRIZ DE BASE NATURAL
English abstract:	In recent years, a shift in perspective towards environmental issues has led to increased research in developing and manufacturing new environmentally friendly materials. Consequently, the search for alternatives to synthetic fibers derived from petroleum and mostly non-biodegradable has emerged. In response to these new challenges, this research proposes the development of composite materials with a polymer matrix reinforced with natural fibers, such as the Furcraea Andina fique plant widely cultivated in Colombia. Based on this, it is necessary to understand the properties of the proposed composite to identify its potential applications as an alternative to synthetic fiber-reinforced composites. The developed composite consists of a Biopoxy36 polymer matrix with a high carbon content reinforced with fique fabric, with two combinations of different densities and braiding methods. Manufacturing processes used include manual laminating, vacuum-assisted laminating, and a proprietary variation. Additionally, an alkaline chemical treatment with 2% sodium hydroxide by weight was conducted to improve the adhesion between the matrix and the reinforcement. The material was evaluated for tensile strength following ASTM D3039 with fiber orientations of 0� and 45�. Subsequently, the stress-life (S-N) curve was determined for R > 0 using uniaxial fatigue tests based on ASTM D3479. A fractographic study was conducted to identify failure modes, and the results were compared with similar materials found in the literature.

Spanish abstract:	En los �ltimos a�os se ha visto un cambio de perspectiva en respuesta a la problem�tica ambiental. Esto ha incitado la investigaci�n en el campo de desarrollo y manufactura de nuevos materiales amigables con el medio ambiente. Subsecuentemente, surge la b�squeda de alternativas al uso de fibras sint�ticas, siendo estas derivadas del petr�leo y en su mayor�a no biodegradables. En respuesta a estos nuevos desaf�os en esta investigaci�n se plantea el desarrollo de materiales compuestos de matriz polim�rica reforzados con fibras naturales, como es el caso del fique Furcraea andina, planta ampliamente cultivada en Colombia. Con base en esto, es necesario conocer las propiedades del compuesto planteado para as� identificar sus posibles aplicaciones como alternativa a los compuestos reforzados por fibras sint�ticas. El compuesto desarrollado consta de una matriz polim�rica de Biopoxy36 con un alto contenido de carbono reforzada con un tejido de fique, del cual se emplearon dos combinaciones con distintas densidades y m�todos de trenzado. Entre los procesos de manufactura utilizados se encuentran el laminado manual, el laminado asistido por vac�o y una variaci�n de autor�a propia. Adicionalmente, se llev� a cabo un tratamiento qu�mico alcalino con hidr�xido de sodio al 2% en peso con la finalidad de mejorar la adhesi�n entre la matriz y el refuerzo. Se ensay� el material a tracci�n siguiendo la norma ASTM D3039 con orientaciones de fibra de 0� y 45�. Posteriormente, se determin� la curva esfuerzo-vida (S-N) para un R > 0 con ensayos de fatiga uniaxial con base en la norma ASTM D3479. Se realiz� un estudio fractogr�fico para identificar los modos de fallo y se compararon los resultados obtenidos con otros materiales similares encontrados en la literatura.
