“…[ 293 ] Combined treatment of NaOH + KMnO 4 toward SPF (sugar palm fiber) reinforced composites offered best mechanical properties with higher tensile strength 9 MPa at 0.125% KMnO 4 and higher tensile modulus 950 MPa at 0.066% KMnO 4 . [ 294 ] Surface modification of abaca fibers by KMnO 4 enhances the tensile strength and moisture resistance properties and can be said that strength is a function of soaking time and concentration of KMnO 4 . Optimal treatment condition of 0.125% concentration KMnO 4 with 3 min duration provides the best tensile strength values and these values are higher by 26.37% than untreated fiber and this could be due to removal of hemicelluloses, lignin, and inorganic substances.…”

Application of natural fiber-polymer composites (NFPCs) in different industrial applications provides competitive edge due to their lightweight, higher specific mechanical properties than glass fibers, sustainability, and lower cost involved in production. There are certain challenges associated with natural fibers and their reinforcement in composites such as poor bonding between the fibers and matrix due to their contradictory nature of characteristics, moisture absorption, lower thermal properties, and poor interfacial adhesion between the natural fiber and polymer matrix. The challenges involved in NFPCs need to be overcome to produce materials with relatively equivalent properties to those of conventional composites and other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and their sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs, is needed for better understanding of the behavior of NFPCs. This work provides the information and holistic view of natural fiber-reinforced composites based on the results obtained from modification techniques, with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix, and enhanced mechanical and thermal properties in the composites.

“…• Potassium permanganate treatment This method consists of immersing fibers in 0.5 wt.% permanganate potassium and acetone for 30 min 11,112 The resulting fibers are washed and air dried for 24 h at a temperature of 105°C. Mohammed et al 111 have treated sugar palm fibers with 0.66 wt.% potassium permanganate leading to an improvement of the tensile properties of treated fibers and their composites. Sanjay et al 112 have reported studies dealing with the effect of 0.05 wt.% of KMnO 4 treatment for 2 min at room temperature on the morphological, tensile, flexural, and impact properties of ramie reinforced polymer composites.…”

To meet the growing demand for the use of environmentally and friendly materials in various applications, many efforts have been done in order to provide lighweighting, biodegradable, and renewable composites leading to a diminution of greenhouse gas emissions. However, they are confronting some challenges that may limit their utilization in industries such as poor interfacial adherence, high moisture absorption, low processing temperature, and impact strength. Several research works have been carried out regarding the mechanical, thermal, and hydric properties of natural fibers reinforced composites to deal with above underlined drawbacks. Actually, based on our analysis, there are two relevant concerns that prevent their integration in other industries such as marine and renewable energy sectors. In this context, the current critical review offers an up to date overview of the factors influencing the properties of the different components of natural fibers composites (fiber, matrix, fiber/matrix interface) as well as their physicochemical, mechanical, thermal and hydric behaviors. Recent works on the mechanical properties of nanobiocomposites based on cellulosic fibers, crystals, and nano-clay fillers are reviewed. The future directions are also discussed to overcome the challenges confronted by these materials, that is, fire resistance and moisture absorption, in order to widespread their utilization especially for wet and fire retardant purposes.

“…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.
