The Inajá (Maximiliana maripa) petiole comes from a native palm tree from Brazil, which can
be found throughout the Brazilian Amazon and neighboring countries, with its highest
incidence in the state of Pará and the Amazon River estuary, reaching Maranhão. The inajazeiro
is mostly used by local residents as food, biofuel source and as raw material for the cosmetics
and medicine industry. Given the abundance and potential of this natural resource, little has
been studied about palm petioles, especially the Inajá petiole. The existing literature on the use
of palm in the area of technological exploration is insufficient, and there is little bibliographic
reference indicating procedures of use, methods and techniques for various application in
engineering. In this sense, in order to enable its use in sustainable technological applications
and, consequently, potentiate a natural and abundant resource in the Amazon, the present work
aimed at the physical-mechanical characterization of the Inajá petiole. The petioles used in the
mechanical tests were unfolded, sectioned and tested according to the American Standard
Method ASTM D143-09. To obtain the density of the petioles, the mass and volume ratio of
the specimens at 12% humidity was used. Inajá presented apparent density of 0.191 g / cm³.
The correlations showed that regardless of the applied effort, the strength and stiffness
properties will be directly related to its density.
