“…Jute and human hair fibers were used to make composites for electrical and thermal insulation applications. The moisture absorption capacity of the hair-mixed composite was lower due to the high thermal stability of the fibers [13]. Human and animal hair fiber-reinforced composites have been used to make crack-free components due to their significant mechanical properties [14].…”

The demand for natural composite products is continuously increasing to make various industrial and commercial products to protect the environment. In this paper, the Hybrid Plant Fiber composite (HPFC) is produced using 64 wt.% of the resin matrix and 36 wt.% of natural fibers (Kenaf, Grewia, and Human hair) by hand layup moulding method. The influences of natural fiber’s weight on tensile, flexural, and impact strengths were investigated by the simplex lattice method. It was revealed that the percentage of contribution of Kenaf and Human hair fibers is higher on Tensile strength, Flexural, and Impact strengths than Grewia fiber. The optimum weight percentage of fibers: 13.5 wt.% of Kenaf, 15.3 wt. % of Human hair and 7.2 wt.% of Grewia of fibers weights have been used to produce desirable mechanical strengths of HPFC. The mechanical properties of HPFC have been compared to HPFC without Human hair. Tensile, flexural, and impact strength of HPFC is 17.95%, 11.1%, and 19.79% higher than the HPFC without Human hair. The predicted optimum HPFC is recommended to make commercial products for fulfilling consumer demand.

The composite materials are present in nature since the prehistoric era. Applications of fiber-based composite materials are increasing day by day in our society to overcome the raised environmental and economic concerns. Hence, waste fiber can be utilized as the best resource to develop composites. The present study deals with the impact of hybridization on the mechanical, thermal, and water absorption behavior of hair and coir fiber-based hybrid composites. The compression molding technique was used to develop the hybrid composites with fixed fiber content (15 wt.%) and was also varied the relative weight percentage of hair and coir fibers [(100% HF), (75% HF/25% CF), (50% HF/50% CF), (25% HF/75% CF) and (100% CF)] in reinforcing phase with HDPE composites S1, S2, S3, S4, and S5, respectively. The composite S2 was achieved superior mechanical attributes as compared to other hybrid/non-hybrid composites. The composite S2 was improved the tensile strength 5% and 35.2% more in comparison to composites S1 and S5, respectively. The thermal behavior (TGA, DTG, and DTA) was also influenced by the blending ratio of fibers of composites. The 5% and 50% weight losses of composite S2 were observed at higher temperature 343.8°C and 465.8°C as compare to other composites, which showed the thermal stability of composites S2. SEM analysis was used to investigate the strength of the fiber-matrix interface, which was shown a significant connection between mechanical and thermal behaviors. The crystallinity of hybrid and non-hybrid composites was examined by using the X-ray diffraction (XRD) analyzer and composite S2 was achieved 326 × 10−9 m crystal size at 21.053° peak position with wavelength 1.5406 × 10−10 m for Cu. The water absorption test was used to examine the moisture resistivity of composite materials, which was helpful to increase the applications of materials in humid areas.

“…The use of natural fibers improved the mechanical property of the composites. Aofei et al [4] studied the effect of chemically treated natural fibers such as kenaf using organic solutions such as NaOH, NaClO 2 , K 2 Cr 2 O 7 , H 2 O 2 , and KMnO 4 . The H 2 O 2 -treated fiber shows 40 % of cellulose content, 26.8 % of crystallinity, and 18.9 % tensile strength compared to other treatments of fibers.…”

Composite products (polymer based) finds application in industries such as automobiles, space, home appliances, the navy, and defense. This paper focused on preparing a composite specimen with natural fibers such as kenaf, grewiaserrulatta (grewia), and human hair to replace synthetic fiber. Epoxy resin BA LY 556 (Bisphenol-A) is considered a matrix material. Four specimens are prepared with 195 g of matrix and 105 g of fibers in the weight fraction method. Among 105 g fibers, the grewia fiber of 15 g is fixed constant, and the remaining 90 g of fibers, namely kenaf and human hair, are distributed as 0 g, 22.5 g, 67.5 g, and 90 g, respectively. As per ASTM standards, the mechanical property investigation was conducted, namely tensile, flexural, and impact tests. The result shows that the highest mechanical strength, i.e., tensile, flexural, and impact, are obtained in specimen A which is composed of 195 g matrix, 90 g kenaf, and 15 g grewia. Also, specimen B shows the highest strength in flexural properties, composed of 195 g matrix, 15 g human hair, and 90 g grewia. Additionally, microscopic analyses are conducted to verify the orientation and substrate bonding of fibers in the composites.
