“…These figures were similar to the composites presented by [18], which analyzed composites made from sugar cane bagasse with 3 mm thickness. According to [19], the study of the flexural strength of composites allows to evaluate the material behavior in flexural resist to forces applied perpendicularly longitudinal axis.…”

Aiming to minimize the environmental pollution and reducing the production costs of the composite materials, the use of plant fibers improves their physical and mechanical properties. On the other hand, fibers have high water absorption, which may increase their volume and weaken the fiber/matrix interaction, affecting the mechanical features of the composites. Concerned with this problem, this research had the objective of making 3 and 10 millimeter-thick specimens, containing 23% (m/m) of Caroa fibers and 73% (m/m) of unsaturated polyester. Samples were withdrawn after 0, 2, 4, 7, 12 and 21 days of exposure at room temperature water (ASTM D570 − 98). Then, the test of tensile (ASTM D 3039), flexural (ASTM D 790-03) and impact (ASTM D 256) was realized and the mechanical properties were analyzed. The samples subjected to humidity had their fibers degraded and presented loss of mechanical properties, more significant in composite with 3 mm. For example, the reduction of the strengths tensile, after 21 days of test were 80% for composites with 3 mm and 60% for composites with 10 mm. Studies like this are important for long-term applications of such composites in humid environments.

“…At last, it is worth mentioning that this work presents for the first time the properties of this fiber, and that the overall set of properties obtained showed that this material can be used to advantage in polymer matrix composites. In fact, tururi fiber-castor oil based polyurethane matrix composites have suitable properties to be used in several products, such as furniture and parquet floors [30].…”

Ubuçu (Manicaria saccifera) is a natural palm found in the Brazilian Amazon estuary. This palm has its fruits protected by a fibrous sac, called tururi, from where a natural mat like material can be extracted. Although the ubuçu palm has local economic importance, the physical, mechanical and chemical characteristics of its fibers have not yet been reported. In this work, in natura tururi fibers were analyzed by thermal analysis (TGA), X-rays diffraction, FT-IR and DSC. The morphology of the fibers was characterized through SEM/EDS, and the tensile breaking load of the fibers' natural mat was also determined. The results show that the fibers have a crystalline index of 60.6%, and are thermally stable up to approximately 264°C. The activati°n energy of the main thermal degradation process was found to be 180.2 kJ/mol. Silica rich protrusions were identified at the fibers surface and the fibrous mat has and apparent density of 0.97 g/cm3, and a tensile breaking load of 432 N.

“…Among those, pouch-like bracts of closely woven texture (termed natural fabric), which temporally cover the entire inflorescence and the pendant infructescence (see Fig. 1), are a promising source to create new composites [38]. Hence, this work presents a systematic study of this natural fabric extracted from the Manicaria saccifera's bracts as a possible reinforcement in composites.…”
