“…According to Del Pino et al 20 , fiber content is the main factor affecting biocomposites' tensile strength. For example, epoxy resin composite 25wt% curauá fiber, treated with NaOH, showed a 3-fold increase in tensile strength compared to the pure epoxy polymer.…”

The packaging industry is the industrial segment that, historically, is one of the largest consumers of polymers, highlighting the great use of polypropylene. Seeking to reduce the consumption of non-renewable raw materials in packaging, this work aimed to study the use of bamboo fiber in polypropylene composites with 15wt% and 25wt% of fiber. Also, the mechanical and thermal properties were evaluated. The density and fluidity of the composites were compared with the virgin polymer. Regarding the density of the composites, it was observed that this was not significantly affected by the addition of fibers. In the melt flow index of the composites, it was observed that the fluidity of the composite with 25wt% bamboo fiber was reduced by more than 50%. The fluidity of the composite with 15wt% fiber has not undergone considerable change compared with the data of the virgin polymer. In tensile analysis, the only property that increased with adding fibers to the polymer was the modulus of elasticity. The impact resistance analysis showed that the composites significantly increased impact resistance and energy absorption. It was concluded that the composites of PP with bamboo fiber showed potential application in the packaging industry.

In order to improve the adhesion of the fibre and reduce the water absorption, the surface of the fibre can be modified by physical or chemical methods [7][8].

Engenharias em perspectiva: Ciência tecnologia e inovação Capítulo 1geotextiles (T55 and T25), as well as a needle-punched non-woven polyester geotextile (NT10), were used. The methodological approach included direct shear tests, applied to compacted samples under the energies defined by the Standard and Modified Proctor, both in configurations without geosynthetic inclusions (for reference) and in configurations that included the geotextiles. Special attention was given to the shear strength parameters of the interfaces, considering the stiffness of the geosynthetics, the typology of the soils, and the level of compaction energy. The most notable results indicated that: i) the interface friction angles (δ) were typically lower than ...

“…The application of lignocellulosic fibres as reinforcements in composite materials has found increasing use in recent years to replace synthetic fibres such as glass, carbon and aramid fibres due to the characteristics of natural fibres such as their low cost, low density, high specific modulus, economic and environmental advantages, biodegradable, abundant and with many technical qualities [1][2][3][4], These advantages place lignocellulosic fiber composites among high-performance composites with economic and environmental advantages [5][6][7]. Although completely synthetic composites dominate the It is known that the mechanical performance of a composite material strongly depends on the nature, orientation of the fibres, the nature of the matrix and also on the quality of adhesion between the two components [18][19][20][21]. Treatment of plant fibers with sodium hydroxide (NaOH) is an effective solution to dissolve their non-cellulosic substances and reduce their sensitivity to moisture or water, and improve fibermatrix adhesion in composites [22][23][24].…”

The application of lignocellulosic fibers as reinforcements in composite materials has found increasing use in recent years, due to the attractive characteristics of natural fibers such as their low cost, high specific modulus, biodegradability, abundance and with many technical qualities. Natural fiber hybrid composites are very frequently used in automotive aerospace and other industries. In this work, numerical and experimental analysis is carried out to compare curauá, jute and sisal fibers in epoxy composites for use in industry. The most appropriate hybridization effect by establishing the amounts of each fiber on the mechanical properties was considered. Finite Element Models were designed and validated through mechanical tests. The number of Finite Element models and specimens performed was determined through the design of experiments using the Taguchi Method and then the results were statistically validated. Higher strength was obtained in composites made with curauá fiber, followed by jute and sisal fibers. Such behavior was achieved by FEM and experimental tests, revealing an increase in tensile strength by increasing the amount of fibers up to 35% in total. Higher strength was achieved when the composite was made with curauá (20 wt.%), jute (10 wt.%) and sisal (5 wt.%) fibers. The results show a good agreement between the FEM and the experimental tests. Furthermore, the results of the present study were compared with those obtained previously mentioned in the open literature.
