Abstract:
There are several species of Amazonian palm trees that can be obtained: food and oils, medicines, construction material, handicrafts, textiles, reinforcement for composite materials, among others. Considering the textile fibers, three palm origins stand out: the tucum (Astrocaryum vulgare), buriti (Mauritia flexuosa) and tururi (Manicaria saccifera). In this work, tucum fibers, obtained from grown leaves, will be investigated. Tucum fibers are used in the manufacture of fabrics, crafts, nets, threads and fishing nets. The material is constantly used by the riverside population of the Amazon and by artisans, fashion articles and other products for tourism. The abundant production added to the environmental advantages of natural fibers are necessary, but not sufficient, conditions for the use of fiber as reinforcement in composite materials. One must be concerned with the relationship between the mechanical properties of the fibers and the polymeric resin matrix, in order to see whether a fiber can successfully act as a reinforcement. A first analysis can be done using micromechanical equations. Thus, the objective of this work was to obtain the mechanical properties of the tucum fiber and its composites from the tensile test.
