Abstract Scope |
The fibers extracted from the stem of the sedge (cyperus malaccensis lam.) plant have been investigated as possible composite reinforcement, aiming to discover a possible new fiber for an engineering aplication. Analysis of the distribution of the diameter and how it affects the mechanical properties of seven-islands-sedge. Acording to, ASTM D2101, for the first time in the literature the diameters of the fibers were analyzed by the Weibull method, indicating an inverse depence and a higher tensile strength were achieved for the thinnest fibers. Besides an investigation of the microstructure by a scanning electron microscopy (SEM) have shown a mechanism for this dependence. Also a mathematical hyperbolic relationship have been found to adjust the inverse correlation. |
