“…Animal fibers also possess superior tensile property, higher elasticity, and better aspect ratio. [4][5][6][7] In the past few decades, substantial research work has been carried out to explore the reinforcement mechanism as well as different characteristics of polymer composites incorporated with several cellulose-based fibers/fillers. However, very few research reports are available on polymer composites incorporated with different protein-based fibers/fillers.…”

Polymer composites with low dielectric constant and high thermal conductivity are gaining considerable attention due to their rising demand in various microelectronic applications such as printed circuit boards, connectors, encapsulations, and electrical contacts. In the present investigation, thermal and dielectric properties of a new class of epoxy-based hybridized composites with improved thermal conductivity (k), high glass transition temperature (T g ), low coefficient of thermal expansion (CTE), controlled dielectric constant (D k ), and low dielectric loss (D L ) have been reported. Epoxy-based composites are fabricated by solution casting method with various wt% (0, 5, 10, 15, and 20 wt%) of short hair fiber and with a fixed proportion of micro-sized boron nitride (BN) (10 wt%) particles. Effects of fiber content on different thermal properties of the composites such as effective thermal conductivity (k), CTE, and T g are

“…Previous studies on the investigation of the mechanical behavior of human hair fibers and the various effects of volume fractions have also been discussed with human hair fiber volume fractions of 0, 5, 10, 15, and 20% on mixing epoxy matrix composites. The results of this study indicate that the percentage of fiber 20% has the best mechanical properties compared to others [13].…”

Currently, composite applications range from the automotive, marine, and even aircraft sectors. One of the composites that have attracted a lot of attention from researchers is composites with natural fibres because natural fibre composites can be used as an alternative to synthetic or plastic materials. The low-density nature of natural fibres can provide good stiffness and strength as in fiberglass-reinforced composites. Coconut coir fibre and human hair waste are the basic materials for the manufacture of composites in this study. Because the amount is abundant so it is easy to obtain. The purpose of this study was to determine the effect of the variation of the best volume fraction of natural fibre composites with polyester matrix on the mechanical properties. The method used is hand layup with 3 variations of fibre volume fraction and polyester matrix, respectively 10:90, 15:85, and 20:80 and with the size of short hair fibres with a size of 3 cm and long coconut fibres with sizes according to the length of the print. The ratio of human hair fibre and coconut fibber is 1:1. Each fraction was tested 3 times to be more accurate. The results of the average tensile strength test with the largest ASTM D638 standard are at the volume fraction of 10:90 with a tensile strength of 19.2 MPa and the average impact test strength with the largest ISO 179-1 standard at the volume fraction of 20:80 is 17, 67 kJ/m². This study showed that the higher the fibres fraction in the composite, the lower the tensile strength but the higher the impact strength. Vice versa, the lower the fibre fraction in the composite, the tensile strength increases but the impact strength decreases.

“…2 There are many research accomplishments under plant-based natural fiber like flax, 3 bamboo, 3 hemp, 4 jute, 5 sisal, 6 coconut, 7 kenaf, 8 hibiscus sabdariffa 9 and abaca. 10 Fibers like human hair, 11 cow hair, 12 spider silk, 13 and silk 14 come under animal-based natural fibers which are mainly made of proteins. Silk fiber has an advantage over the plant fiber due to its orderly fiber properties, high fiber strength, linear fibrils type, and relatively better toughness.…”

Natural fibers have been attracting researchers and engineers as an alternative reinforcement of synthetic fibers in polymer composites due to their low cost, availability from natural resources, satisfactory high modulus and tensile strength, and biodegradability. Filature silk waste (FSW) is the remnant part of the cocoons which is produced during the silk forming process. The current study focuses on the comparison of tensile properties between untreated filature silk waste reinforced epoxy-based composite (UTFSWREC), 2 wt% alkali-treated filature silk waste reinforced epoxy-based composites (TFSWREC) and 2 wt% alkali-treated filature silk waste reinforced epoxy nanocomposites (TFSWRENC). The tensile properties showed that Young’s modulus of composites increases with surface modification of fiber and further enhances with nanoclay filler. TFSWREC and TFSWRENC displayed a higher tensile modulus than UTFSWREC. Scanning Electron Microscopy (SEM) showed the removal of the sericin layer from the surface of fiber, which resulted in the separation of fibrils and further resulted in the enhancement of the mechanical properties. FTIR analysis confirmed that intermolecular bonding improves with the chemical treatment and further refined with nanoclay filler addition.
