“…Thus, one could expect a certain level of interaction between the matrix and the sisal fiber, which would be inferred by the coating of the fiber by the matrix. However this effect was not verified due to the hygroscopic characteristic of sisal fibers and the fact that they were not previously treated since such treatments can remove some of the moisture and lignin present in the fibers and improve fiber coverage, as shown in the work of Lima et al 3 and Huang et al 13 .…”

“…Over the past few decades, research interest in developing alternative solutions to replace conventional synthetic fibers present in composites with natural fibers has been growing due to the high demand for ecologically sustainable materials, the desire to reduce the impact on the environment, and the ambition to reduce the costs of polymer composites [1][2][3][4][5] .…”

“…Natural fibers in composites have several advantages compared to synthetic ones, such as low cost, low density, high specific strength, biodegradability, and abundant availability. Currently, there are several natural fibers that are used in polymeric composites, such as sisal, jute, ramie, coconut and loofah fibers 1,3,6,7 . Among these, sisal fiber stands out for its physical and chemical characteristics 3,8 , besides its availability in the Brazilian scenario, due to the fact that of the annual world production of 600 million tons, 200 million tons are produced in Brazil 9,10 .…”

The research interest in developing alternative solutions to replace conventional synthetic fibers with natural fibers in composites is due to the several possible benefits of using these fibers, such as low cost, low density, high specific strength and high availability. The objective of this study was to produce hybrid composites from a commercial ortho-terephthalic unsaturated polyester resin obtained from the recycled PET (polyethylene terephthalate) glycolysis reinforced with sisal/glass fibers obtained by the vacuum infusion process. The composites were produced with 3 layers of fibers, the volume of each layer was fixed, and the amount of resin used was the same. For the results, the relative density decreased up to 23% and the moisture absorption reached up to 10.41%, being possible to observe the influence of the layer arrangement on the results. From the mechanical tests of tensile, flexural and impact strength it was observed that the properties decreased as sisal fibers were added, except in the results of maximum deflection in the flexural test of formulations. From the SEM (scanning electron microscope) analyses showed some defects in the direction of the thickness of all formulations produced, possibly from the process conditions adopted and the moisture present in the sisal fibers, which negatively affected the results of mechanical properties and moisture absorption. According to the results of this study, it was possible to obtain some proposed formulations of hybrid composites, such as the (F1), composed of glass, sisal and glass layers (|GSG), which reached properties close or equivalent to those of the reference composite (F0), composed of glass, glass and glass layers (|GGG) and which showed to be potential alternatives to replace conventional glass fiber composites.

Currently, hybridizing natural fibers with synthetic fiber is considered as the best solution for reducing the environmental pollution and the cost of materials. This is due to the lower mechanical properties and high water absorption capacity problems of natural fiber reinforced composites and nonbiodegradability and high-cost problem of synthetic fibers that can be solved by hybridizing them. This article aims to investigate the influence of the weight fraction of the sisal fiber on the mechanical property of the E-glass-sisal fiber reinforced epoxy matrix composite. The sisal fiber was treated by 8% sodium hydroxide (NaOH) for three hours. The samples of five different weight fractions of fibers (0%, 20%, 30%, 40%, and 60%) with a constant weight fraction of epoxy matrix (40%) were prepared as per the ASTM standard prepared by the manual hand layup method at room temperature. The tensile, compression, and flexural tests of the samples were carried out on the WP 310 universal testing machine. From the experimental results, it has been observed that the increasing weight fraction of the sisal fiber greatly influences the mechanical properties (tensile, compression, and flexural) of E-glass-sisal hybrid reinforced epoxy matrix composites. From all the tested samples, those consisting of 60% E-glass and 0% sisal fibers with 40% epoxy matrix showed better mechanical properties than other hybrid samples with tensile, compressive, and flexural strengths of 464.03 MPa, 40.1 MPa, and 239.06 MPa, respectively.

“…Morphological characterization of ricinus communis fibre-reinforced polyester composite reveals that there is a mechanical interlocking of fibre and matrix, which leads to improved mechanical strength [17]. The rough surface of fibres induced better adhesion with the matrix and imparted more mechanical strength to the composites [18][19][20][21]. Fibre matrix bonding, size, voids, fibre pullout, filler distribution, cracks, etc.…”

Natural fibres find their application as a reinforcing agent for polymer composites to obtain parts with improved mechanical properties. Manufacturing of non-metallic products is incorporated with natural fibres for better strength and to reduce cost. Rotational moulding is a process used for the manufacturing of hollow plastic products, especially water tanks, plastic fuel tanks, barrels, kayaks, refrigerated panels, etc. Incorporation of natural fibres to reinforce polymers in rotational moulding process is a tedious task; since there is no control over fibre and polymer powder mixture, which is rotating bi-axially, it may lead to fibre agglomeration. The present work investigates the mouldability of linear low density polyethylene composites with tampico and coir fibre as the reinforcement agents using a bi-axial rotomoulding machine. NaOH-treated fibres with 5, 10 and 15% by weight have been added to the linear low density polyethylene matrix, and the composites were prepared by rotational moulding process. Mechanical properties such as tensile strength, flexural strength, impact strength and hardness have been investigated. Dynamic mechanical behaviour such as storage modulus, loss modulus and tan δ of the different composites has been investigated with dynamic mechanical analyser. Fractured surfaces were examined qualitatively with the help of a scanning electron microscope for determining the interfacial properties and fibre adhesion between the fibres and the linear low density polyethylene matrix.
