“…Dry PALFs were soaked into a 10wt% NaOH solution at 30°C, maintaining a liquor ratio of 1:10. Fibers were kept immersed for 2h into the alkali solution and afterwards, they were washed with distilled and fresh water several times to remove any traces of NaOH (Maniruzzaman et al, 2012). After washing, the fibers were dried in an oven at 80°C for 24h.…”

Compression molding process was used to manufacture composites reinforced with pineapple-leaf fibers. During manufacturing, four plies of polypropylene with an average thickness of 0.76 mm were used and the fibers were equally distributed between plies to generate a stacked composite with the fibers in external layers transversally oriented to those in the inner layer. Two types of pineapple-leaf fibers were used as reinforcement: untreated fibers and fibers modified in an alkali solution (10% NaOH). Two different fiber contents were also evaluated in order to measure their effect on the mechanical properties of the composite. Ultimate tensile strength, strain at maximum load, Young's modulus, flexural strength and flexural modulus were measured. Tensile strength was increased 22% and Young's modulus increased 60%. Flexural strength and flexural modulus increased 19 % and 50% respectively, with fiber content. However, the alkali treatment did not improve those properties. Fractured surfaces of the composites were examined using electron microscopy and failure mechanisms such as fiber pullout and matrix deformation were observed.

“…Natural fibers such as rice straw [ 20 ], cocoa bean [ 21 ], agave [ 22 ], wood [ 23 ], bamboo [ 24 ], etc., are explored for 3D printing applications [ 25 ]. Additionally, the researchers are focused on developing low-cost materials by utilizing rice straw [ 26 ], rice husk [ 27 ], sugarcane bagasse [ 28 ], olive [ 29 ] and pineapple [ 30 ] leaves, peanut shell, coconut shell, coffee hull, and other agro wastes [ 31 , 32 , 33 , 34 ] for other technical applications.…”

In recent days the rising concern over environmental pollution with excessive use of synthetic materials has led to various eco-friendly innovations. Due to the organic nature, abundance and higher strength, natural fibers are gaining a lot of interest among researchers and are also extensively used by various industries to produce ecological products. Natural fibers are widely used in the composite industry as an alternative to synthetic fibers for numerous applications and new sources of fiber are continuously being explored. In this study, a fiber extracted from the Furcraea foetida (FF) plant is characterized for its feasibility as a reinforcement to fabricate polymer composite. The results show that the fiber has a density of 0.903 ± 0.07 g/cm3, tensile strength (σt) of 170.47 ± 24.71 MPa and the fiber is thermally stable up to 250 °C. The chemical functional groups and elements present in the FF fiber are evaluated by conducting Fourier transform infrared spectroscopy (FT-IR) and energy dispersive spectroscopy (EDS). The addition of FF fibers in epoxy reduced the density (13.44%) and hardness (10.9%) of the FF/Epoxy (FF/E) composite. However, the void content (Vc < 8%) and water absorption (WA: < 6%) rate increased in the composite. The FF/E composite with 30% volume of FF fibers showed maximum σt (32.14 ± 5.54 MPa) and flexural strength (σf: 80.23 ± 11.3 MPa).

“…Over the past few decades, very intensive research work has continued to better understand the chemical treatment behaviour of cellulosic fibres. Presently, mercerisation [241][242][243][244][245], acetylation [246][247][248][249], peroxide treatment [250][251][252], permanganate treatment [253][254][255][256][257], silanization [258][259][260][261][262][263][264], acrylation [265][266][267][268][269], acrylonitrile grafting [270][271][272] and latex coating [273][274][275] are the chemical modification techniques most used to improve the reactivity of the natural fibres with the polymeric matrix materials. The hydrophilicity reduction of the cellulosic fibres by eliminating the proportions of hydroxyl groups (-OH) is the ultimate objective of the abovementioned chemical modification techniques [24].…”

Plant-Based Natural Fibre Reinforced Composites: A Review on Fabrication, Properties and Applications

The increasing global environmental concerns and awareness of renewable green resources is continuously expanding the demand for eco-friendly, sustainable and biodegradable natural fibre reinforced composites (NFRCs). Natural fibres already occupy an important place in the composite industry due to their excellent physicochemical and mechanical properties. Natural fibres are biodegradable, biocompatible, eco-friendly and created from renewable resources. Therefore, they are extensively used in place of expensive and non-renewable synthetic fibres, such as glass fibre, carbon fibre and aramid fibre, in many applications. Additionally, the NFRCs are used in automobile, aerospace, personal protective clothing, sports and medical industries as alternatives to the petroleum-based materials. To that end, in the last few decades numerous studies have been carried out on the natural fibre reinforced composites to address the problems associated with the reinforcement fibres, polymer matrix materials and composite fabrication techniques in particular. There are still some drawbacks to the natural fibre reinforced composites (NFRCs)—for example, poor interfacial adhesion between the fibre and the polymer matrix, and poor mechanical properties of the NFRCs due to the hydrophilic nature of the natural fibres. An up-to-date holistic review facilitates a clear understanding of the behaviour of the composites along with the constituent materials. This article intends to review the research carried out on the natural fibre reinforced composites over the last few decades. Furthermore, up-to-date encyclopaedic information about the properties of the NFRCs, major challenges and potential measures to overcome those challenges along with their prospective applications have been exclusively illustrated in this review work. Natural fibres are created from plant, animal and mineral-based sources. The plant-based cellulosic natural fibres are more economical than those of the animal-based fibres. Besides, these pose no health issues, unlike mineral-based fibres. Hence, in this review, the NFRCs fabricated with the plant-based cellulosic fibres are the main focus.
