“…Currently, there are solutions to improve the adhesion between fibers and matrices. These are the chemical treatment of fibers, which include, for example, alkaline treatment [11,[13][14][15][16] , silane treatment [14][15][16] , acetylation of natural fibers [14,15,17] , benzoylation treatment [14,15] , acrylation [14,18] , acrylonitrile grafting [14] , permanganate treatment [14,18] , peroxide treatment [14,15] , isocyanate treatment [14,15] , etherification of natural fibers [14] , plasma treatment [19] , sodium chlorite treatment of natural fibers [20] and maleated coupling agents [14,21] .…”

Effect of coupling agents on properties of vegetable fiber polymeric composites: review

Using natural fibers in composites presents a wide range of applications, from furniture to airplanes. In polymeric composite, the use of fiber is to boost strength and stiffness. However, this material presents low mechanical properties compared to virgin polymers due to hydrophilic nature of the fiber and hydrophobic nature of the polymer. It can result in weak bonding matrix/fiber which may cause incompatibility problem in bonding fibers with most of the polymer matrices. To achieve compatibility between surfaces there is a need to modify them, and one alternative is using coupling agents. Maleated coupling agents stand out as option, but their source is petroleum-derived polyolefin. Researchers have been seeking for more environmentally friendly alternatives to replace these materials. Therefore, this work aims to bring a comprehensive review of the mechanical behavior of maleated and ecological coupling agents. Based on the literature, resistance, flexural, and tensile strength were properties discussed.

“…121 The acetylation treatment can decrease the hygroscopic nature of usual fibers. 122 As, it improves (1) the dispersion of fibers in a polymer matrix and the interfacial bond strength in the final composites, 120 (2) the tensile and the flexural strengths of the composites. 123 Some studies of the effects of the acetylation treatment are presented in Table 7.…”

This paper presents some principles of research done on the assessment of fiber-matrix adhesion and durability in cement-based and polymer-based composites reinforced with vegetable fibers. Natural vegetable fibers are light, biodegradable and low-cost; however, their compatibility with both matrices - which are generally hydrophobic- is poor, because of their hydrophilic character. This review presents the different strategies proposed in literature to improve (1) interfacial bonding between matrix and fibers and (2) sustainability of composite materials reinforced by vegetable fibers. In order to achieve these goals, searchers investigate chemical or/and physical treatments of fibers and/or matrix modification of composites materials. The impacts of these strategies are followed in terms of mechanical properties, thermal properties, morphology and water absorption of the composite materials. Authors proposed to focus on the influence of aging on these characteristics in order to estimate durability.

“…In the contemporary landscape of materials science and engineering, the integration of natural fibers into Fiber Reinforced Polymers (FRPs) has emerged as a promising avenue for sustainable and high-performance composite materials. Natural fibers, derived from plants, offer notable advantages such as renewability, low cost, and environmental friendliness [1][2][3][4]. Among these natural fibers, Hibis-cus Rosa-Sinensis plant fibers have gained significant attention owing to their widespread availability and unique mechanical properties [5][6][7].…”

Incorporation of natural fibers with Fiber Reinforced Polymers (FRPs) is a promising avenue for sustainable and high-performance composite materials. The fibers, derived from outer bark portion of plants, offer significant merits such as renewability, low cost, and eco-friendly. Unique mechanical and physical properties, and widespread availability of Hibiscus Rosa-sinensis have made them subject of intense research interest. The present study investigated the chemically treatment of HRS Fibers using Sodium Hydroxide (NaOH), Potassium Permanganate (KMnO4), and Acetic Acid (CH3COOH) bat varying weight percentages (3, 4, 5 Wt.%) and solutionizing times (1, 2, 3 hours) based on Taguchi’s L27 orthogonal array. Fourier Transform Infrared (FT-IR) analysis revealed significant changes in O-H, C-H stretching, C=O moiety, aromatic ring, and C-O/C-C stretching. Potassium Permanganate treatment at 4 Wt.% and 3 hours of solutionizing time has yielded the best results. Multi-Layer Perceptron Artificial Neural Network (MLP-ANN) has been successfully applied to accurately predict the output physical characteristics of chemically treated HRS fibers using experimental data. Further Single Fiber Pull-out test results in Potassium Permanganate at 4Wt.% and 3 Hours solutionizing time as best sample with highest Tensile Strength and Modulus. This research underscores the effectiveness of the chemical treatment process in enhancing the properties of HRS plant fibers for potential composite applications.
