Madeiras amazônicas para produção de tacos de beisebol

Abstract

The purpose of this study was to evaluate species of woods from Amazonia forest with technological potential for making baseball bats. For this, it was used as a parameter fundamental properties of wood inherent in the product. First was created a database with all the technology described species, including the very American species to baseball bats. Given the wide variety of species from Amazonia forest , the method used three steps in order to sift through the data. It began with the multivariate analysis, which determined 4 groups by similarity. These groups was selected those who had species from Amozonia forest along with other species used for baseball bats (Acer saccharum, Fraxinus americana, Betula alleghaniensis and American Patagonula).Later, the species from the selected groups were compared to the list of commercially exploited woods. Crossing intersection removed all species with different grain classification then straight grain type. Therefore, there were only three species - Endopleura uxi, Qualea paraensis and Roupala montana, the last two of which have been selected for making prototypes, since the first unfavorable characteristics presented in the drying process. The prototypes were evaluated by amateur players from adult and master Amazonas selection team. From all species from Amazonia forest, the Qualea paraensis was the one that had the best result, with its final mass of 838g to 12.9% moisture content, similar to the original baseball bats - which demonstrates its quality, since the mass factor It has great influence on product qualification.
