“…The natural fiber consists of a great amount of lignocellulose, which plays an important role in acetylation, where the lignocellulose reacts with the acetic anhydride resulting in esterification of the hydroxyl groups in the cell wall, forming the acetic acid as a byproduct, as shown in the scheme [73] Cellulose-OH + CH For the above reaction, a limited amount of liquid acetic anhydride is employed without a catalyst or co-solvent, and high temperatures typically between 120 and 160°C are used for the commencement of the reaction [23,38,74]. Improvements in the specific strength and hydrophilic nature of natural fiber was observed using acetylation [75][76][77][78][79][80].…”

A rapid growth in the research and employment of natural-fiber composites (NFCs) has been observed in the last years. This is explained by their many advantages, such as the biodegradability, eco-friendliness, a relatively low cost, and good mechanical properties. Despite these advantages, they also possess some undesirable features, such as difficulties in processing, high fiber moisture absorption, low impact strength, low durability, poor fire resistance, and poor compatibility between fibers and matrix. Much effort has been applied to minimizing these issues in order to extend the capabilities and applications of this group of materials. In an attempt to provide a better insight into NFCs, an up-to-date review of their manufacturing routes, different applications, and mechanical performance is very required. This review aims to address the above-mentioned issues challenges encountered when dealing with such materials.

“…This treatment also results in a rough surface topology with fewer void substances, thus providing better mechanical interlocking with the matrix. Senthilraja et al [113] reported that the mechanical properties of NFRPCs could be improved through acetylation treatment. These NFRPCs were utilized later for applications like entryway boards, vehicle parts, etc.…”

The utilization of synthetic materials stimulates environmental concerns, and researchers worldwide are effectively reacting to environmental concerns by transitioning towards biodegradable and sustainable materials. Natural fibers like jute and sisal have been being utilized for ages in several applications, such as ropes, building materials, particle boards, etc. The absence of essential information in preparing the natural-fiber-reinforced materials is still a challenge for future applications. Chemical treatments and surface modifications can improve the quality of the natural fibers. Natural-fiber-based composites are a potential candidate for many lightweight engineering applications with significant mechanical properties. In the view of the progressive literature reported in the field, this work aims to present the significance of natural fibers, their composites, and the main factors influencing these materials for various applications (automotive industry, for instance). Secondly, we aim to address different surface modifications and chemical treatments on natural fibers and finally provide an overview of natural fiber reinforced polymer composites’ potential applications.

“…Acetylation turns out to be a valid technique to improve fibers dimensional stability, biological attack resistance and degradation resistance to UV (ultraviolet) radiations [68] but also to improve their mechanical performances and the ones of the polymeric composites reinforced with them, i.e. flax [69], sisal [70], bagasse [71], banana [72] and palm [73] fibers.…”
