TL;DR: In this paper, the authors have reviewed the different sources of natural fibers, their properties, modification of natural fiber, the effect of treatments on natural fibers and their effective use as reinforcement for polymer composite materials.
Abstract: The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.

TL;DR: In this paper, a review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values, which is important to determine the optimal intended uses for instance as high quality bio-composite raw material.
Abstract: Understanding the basic properties of natural fibers is important to determine the optimal intended uses for instance as high-quality bio-composite raw material. This review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values. The natural fibers have low density and high strength to weight ratio and reduction make them potential as light weight composite and reinforcement materials. The microstructure and chemical compositions of fibers affect the mechanical properties with the fiber cross-sectional area is the most variable influencing the fiber strength. Natural fibers are easy to absorb water due to the presence of hemicellulose that give hydrophilic properties make them less compatible in the interaction with matrix with hydrophobicity properties. Higher cellulose content and crystallinity tend to result better strength properties of fiber while lignin is since versa. Besides that, fiber anatomical characteristics vary between different and same species that affect on the density and mechanical properties. The other factors namely environmental conditions, method of transportation, storage time and conditions, and fiber extraction affect the size and quality of the natural fibers.

TL;DR: A review of recent developments of bamboo fiber-based reinforced composites, its processing methodology, and applications is given in this article, where the focus is on low-cost polymeric-reinforced composites using entirely biodegradable fibers.
Abstract: The dominant emerging materials from more than 30 years ago are plastics, ceramics, and composite materials. Composite materials have steady growth in the volume and number of its applications as it enviably penetrates existing markets while creating new ones. Contemporary composite materials are well established in today’s market of specialty and everyday products with its proven worth as weight-saving materials. There is a current challenge of cost-effectiveness and environmental friendliness, thus leading to the search for low-cost polymeric-reinforced composites using entirely biodegradable fibers. Bamboo fibers have provided some response in the production of materials that are recyclable, biodegradable, and sustainable. The natural fibers yield composites with high strength-to-weight ratios as a function of the best properties of each component. Researchers have found sustainable high-end quality industrial products that can be generated from raw materials like bamboo fibers. Due to its high strength-weight ratio, bamboo fibers are often used to replace natural glass fiber. Thus, the much attention has been given to its composites with different matrix materials. This article gives a review of recent developments of bamboo fiber-based reinforced composites, its processing methodology, and applications.

TL;DR: In this article, the authors investigated physical characteristic, mechanical properties, and chemical composition of heat-treated bamboo scrimbers for 2-h. Specimens were heated at 50-230°C in laboratory conditions for 2 hours and the results of heat treatment samples were compared with the controls.
Abstract: This study aims to investigate physical characteristic, mechanical properties, and chemical composition of heat-treated bamboo scrimber. Specimens were heated at 50–230 °C in laboratory conditions for 2 h. Test results of heat treatment samples were compared with the controls. Moisture absorption decreased slightly and then increased as temperature increased. It was probably due to changes of crystallinity and chemical structure. Mechanical properties varied greatly according to different temperature levels. Failure types reflected treatment temperature to some extent. Compressive strength reached a maximum when fiber bundles fractured neatly at 170 °C, which is a turning point for physical, mechanical, and chemical properties under this heat treatment condition. Increasing mechanical properties of bamboo scrimber after heat treatment was due to solidification of phenolic resin.
