Here we present a morphological and nanomechanical characterization of the parallel section of the axis of guadua Angustifolia kunth fibers (GAK) from Colombia, focusing on properties such as hardness (nanoindentation), roughness and topography. Our method was based on the application of scanning electron microscope (SEM) and atomic force microscope (AFM). AFM provided curves of force by displacement, as well as characteristics of dynamic nanoindentation systems and images. Their analysis revealed ridges and valleys on the surface of GAK fibers. The estimated surface roughness of 9.51 nm suggests an adequate value to provide superior adhesion between polymer and fiber. The same conclusion follows from our measurements of hardness, reduced modulus and nanoscale topography. Due to their excellent properties, we conclude that GAK fibers represent an ideal reinforcement material in polymer matrices. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49659032018 https://www.redalyc.org/journal/496/49659032018/ https://www.redalyc.org/journal/496/49659032018/html/ https://www.redalyc.org/journal/496/49659032018/49659032018.epub https://www.redalyc.org/journal/496/49659032018/movil 10.15446/dyna.v85n206.70889 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.206 Vol.85 |
