DETERMINACIÓN DEL COMPORTAMIENTO VISCOELÁSTICO Y MODELO REOLÓGICO EN LAS FIBRAS DE HOJAS DEL Agave angustifolia Haw

Abstract

In the present study was to determine the properties and attributes that characterize the fibers extracted from the leaves of Agave angustifolia Haw, area and shape of the cross section, the mechanical tension that identifies the fibers of Agave angustifolia Haw. The experimental procedure began with the extraction of the fibers by hand, then measured the length of the fiber was subsequently measuring the area of the cross section using an optical microscope, with the support of a camera attached to microscope take pictures, and analyzed using a computer program, then were tested for resistance to stress fibers agaves 5, 7 and 9 years, in three layers of agave and in three different regions of planting. The tensile strength and percentage strain of agave fibers is higher in 5 years. In creep tests agave fibers were tested 5, 7 and 9 years in three regions and three layers of agave. Behavior is observed at constant load of 3 N after 180 seconds. With these results we conclude that the type of mechanical behavior that identifies the fibers from the leaves of Agave angustifolia Haw is permanent viscoelastic deformation and an elastic response which is based on a four-parameter model.
