| dc.description | Analizamos el efecto del tratamiento de Etching físico en el módulo de Young y la apariencia superficial de fibras de Guadua angustifolia. Las fibras fueron bombardeadas con iones de argón a diferentes niveles de energía y tiempos de exposición mediante un método de grabado en seco. El análisis por microscopía electrónica de barrido (MEB) reveló que el bombardeo iónico modificó la morfología superficial de la fibra, aumentando su rugosidad. El uso de una mayor energía de plasma con tiempos de exposición más cortos produjo efectos similares a los obtenidos con una energía menor y tiempos de exposición más largos. El aumento del módulo de Young estuvo directamente relacionado con cambios en la estructura superficial de la fibra. Estos hallazgos confirman la influencia del tratamiento con plasma en las propiedades mecánicas de las fibras y abren nuevas posibilidades para su aplicación como refuerzo en materiales compuestos. | |
| dc.description.abstract | We analyzed the effect of dry etching plasma treatment on the Young’s modulus and surface appearance of Guadua angustifolia fibres. The fibres were bombarded with argon ions at different energy levels and exposure times through a dry etching method. Scanning electron microscopy (SEM) analysis revealed that ion bombardment modified the fibre surface morphology, increasing roughness. Using higher plasma energy with shorter exposure times produced similar effects to those obtained with lower energy and longer exposure times. The increase in Young’s modulus was directly related to changes in the fibre’s surface structure. These findings confirm the influence of plasma treatment on the mechanical properties of the fibres and open new possibilities for their application as a reinforcement in composite materials. | |
