Abstract:
Due to modern advances in the area of polymeric composites matrix reinforced by vegetable natural fibers, increasing demand for technologies that contribute as a potential for expansion and optimization, both the structural point of view, environmental, sustainable and the sectors of renewable energy, it is necessary studies that prioritize an approach precisely in the intersection of all these scientific and technological contemporary challenges. The development of this research fulfills a first experimental stage of a relevant academic research nowadays, which consists of evaluating the potential of application of a epoxy matrix composite reinforced by ramie fibers fabric in the wind sector, such proposed experimental design aims to obtain an average value for the density of natural fibers in question in the acquired fabric and by occasional necessity, the adequacy of the pycnometers to what prescribes relevant standards to the tests. Therefore, a statistical validation was sought, even for these glass instruments, considering that it cannot be considered, at first, the hypothesis that they would be in identical conditions of use. Thus, the experimental methodology consisted in the design of four treatments or groups representing each of the four pycnometers available. After performing the tests and obtaining the pertinent measurements, an one-way ANOVA demonstrated the statistical non significance among the mathematical differences presented by the density means of the ramie fibers that form the fabric, thus evidencing a validation regarding the equivalence of use for the glass instruments employed and, consequently, a general mean could be calculated assuming all forty measurements obtained in the laboratory. Finally, a comparison of this general mean with specific literature values showed excellent similarity among both, fact that provides reliable data to the continuity of a whole research that intend to combine a composite material with better biodegradability than the synthetics, sustainability and reduction carbon emissions which intensify the greenhouse effect
