| dc.description.abstract | This paper presents the study of the mechanical properties of technical fibers extracted from the Stipa Obtusa grass considering three different alkali treatment times, 1.5, 3 and 5 h; additionally, fiber/matrix compatibility is evaluated via the single fiber fragmentation test, and the best treatment in terms of mechanical properties and compatibility is used to test the effect of gage length, strain rate and cyclic deformation. Result shows that mechanical properties increase with treatment time until a maximum (strength similar to 569 MPa, modulus similar to 28 GPa and strain 0.026), and afterwards decreases; furthermore, strength and strain decreases as the fiber length increases; while, the strain rate's effect is negligible unless at very low speed, and a cyclic deformation leads to an increase of the modulus (similar to 13%). It can be concluded that fibers extracted from the Stipa Obtusa show potential and can compete with commercial natural fibers as a reinforcement in polymeric matrix composites.||Este trabajo presenta el estudio de las propiedades mecánicas de las fibras técnicas extraídas del pasto Stipa Obtusa considerando tres tiempos diferentes de tratamiento alcalino, 1.5, 3 y 5 h; además, la compatibilidad fibra/matriz se evalúa a través de la prueba de fragmentación de una sola fibra, y el mejor tratamiento en términos de propiedades mecánicas y compatibilidad se utiliza para probar el efecto de la longitud calibrada, la velocidad de deformación y la deformación cíclica. El resultado muestra que las propiedades mecánicas aumentan con el tiempo de tratamiento hasta un máximo (resistencia similar a 569 MPa, módulo similar a 28 GPa y tensión 0,026), y luego disminuye; además, la resistencia y la tensión disminuyen a medida que aumenta la longitud de la fibra; mientras que el efecto de la velocidad de deformación es insignificante a menos que a muy baja velocidad, y una deformación cíclica conduce a un aumento del módulo (similar al 13%). Se puede concluir que las fibras extraídas de la Stipa Obtusa muestran potencial y pueden competir con las fibras naturales comerciales como refuerzo en compuestos de matriz polimérica. | |
