Utilizing recycled or short fibers for making useful engineering composite component is a present research trend and requirement. Current research work explicates the effect of short carbon fibers (SCF) used as secondary reinforcement in woven glass/epoxy hybrid composites and evaluates their mechanical properties. Different concentrations (0.1, 0.3, and 0.5 wt%) of SCF were incorporated to assess the tensile, flexural, and interlaminar fracture toughness (Mode I and II) of the resulted composites. Composites with 0.1 wt% SCF showed 29.02% and 16.08% increment in the tensile and flexural strength, respectively. For Mode I and Mode II interlaminar fracture toughness tests, 0.1 wt% SCF‐GE samples showed the highest strain energy release rate. Double cantilever beam specimens were used for Mode I testing and an improvement of 13.49% in GIC value was observed. End‐notched flexure method was used for the Mode II tests, and 0.1 wt% SCF‐GE samples showed 20.45% increase in GIIC values. This paper explains the various reasons and mechanisms for obtaining such results. Scanning electron microscopy of the fractured surfaces was carried out to perceive the diverse failure micro‐mechanisms that could have been involved.

“…The fibers are virtually pure cellulose, nature's most prevalent polymer, with minor amounts of waxes, lipids, pectin, and water [18]. Cotton fibers are composed of 85-90 percent cellulose, 0.1% pectin, 5.7% hemicellulose, and 0.6% wax [19]. Chemical composition varies with variety, growth conditions (water, soil, pests, temperature, and so on), and maturation.…”

This study includes the manufacture of two sets of composite materials consisting of polymethyl methacrylate reinforced with natural fibers. The first (R) group included eight layers of cotton with one layer of hair in the middle, and the second (O) group included six layers of cotton with three layers of burlap in the middle. The thermal conductivity of the two groups was checked using a Lee disc to identify the thermal conductivity (K), of group R 0.0771 w/m.c, and of group O 0.0754 w/m.c. These values are considered good as the material has good thermal insulation due to its low thermal conductivity values and is therefore suitable for use in prosthetic limbs as it can preserve the body temperature from external influences.

Natural cellulosic fibers have garnered significant attention in recent years due to their potential as eco-friendly and sustainable alternatives to synthetic materials in various industries, such as composite reinforcement, textiles, and packaging. The successful utilization of these fibers depends on understanding their properties, which can be achieved through comprehensive characterization methods. This mini-review discusses the extraction, treatment, and characterization of natural cellulosic fibers, focusing on the latest advancements in these areas. The extraction methods of natural cellulosic fibers, including chemical, physical, and biological processes, are discussed. The choice of extraction method impacts the fiber’s morphology, crystallinity, and purity, which ultimately affects its performance in different applications. Surface modification methods, including chemical treatments like treatment, acetylation, silane treatment, grafting, bleaching, and physical treatments such as corona treatment, plasma treatment, and UV/ozone treatment, are also explored. These treatments can enhance the compatibility and performance of natural cellulosic fibers in various applications. Characterization techniques for natural cellulosic fibers are reviewed, including mechanical properties testing (tensile strength, flexural strength, and impact strength), morphological analysis (scanning electron microscopy (SEM) and transmission electron microscopy (TEM)), and advanced techniques such as atomic force microscopy (AFM), confocal Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). Furthermore, the application of the Weibull distribution for analyzing the tensile strength of natural cellulosic fibers is discussed, providing valuable information on the fiber’s strength distribution and reliability. This review highlights the importance of comprehensive characterization methods in understanding the properties and potential applications of natural cellulosic fibers. The continued development of these techniques will be crucial for the advancement and commercialization of these sustainable materials as eco-friendly alternatives to traditional materials in a wide range of industries.
