Composite materials are formed by two or more constituents at macroscopic level. Type and form of fiber plays a vital role in imparting required properties to the composite. Many researchers contributed to the development of artificial fiber composites which are not environmental friendly in nature. Sizable research is also done in the area of natural fiber composites. Human hair is a non-biodegradable waste available in abundant quantity across the world, but is rarely explored for applications in engineering fields.  In the present study, a review on behavior of human hair fibers was made to understand their suitability as a reinforcing material in composites. Morphology of the hair fibers is reviewed and the density of the hair fibers was determined using Archimedes principle. Tensile strength of the hair fibers is experimentally estimated. Chemical resistivity and burning tests were conducted. Tensile and flexural properties of hair fiber reinforced polyester composite were experimentally determined and compared.

Abstract Epon 826 epoxy resin in conjunction with Epikure 3140 curing agent was used in this study to fabricate underfill composites. Nanofiller of 500nm hexagonal boron nitride (hBN) was incorporated in the underfill epoxy using ultrasonication technique to alter their thermal and viscoelastic properties. Filler contents ranging from 1% to 5% volume fraction (vol.%) were used to investigate changes in thermal behavior and viscoelasticity of underfill with an increase in filler loading. Thermal analysis has shown an increase in thermal conductivity of the underfill by increasing the filler loading. Using 5% vol.% of 500nm hBN nanofiller a thermal conductivity of 0.32 W/m.K was obtained as compared to neat epoxy with thermal conductivity of about 0.2 W/m.K, showing an enhancement in thermal conductivity of the underfill material. Furthermore, studying viscoelastic properties of fabricated underfills suggested the influence of filler and filler loading on viscoelasticity of underfill.

Hair Fiber

Human hair is a biofiber having an exceptional chemical composition, higher strength in tension, and slow decomposition rate. In the present work, composites are fabricated by simple hand layup technique with epoxy matrix and different proportions of hair fiber (0, 5, 10, 15, and 20 wt%). Physical, mechanical, microstructural, and thermal characterization of the composite samples has been done by following the proper ASTM standards. A theoretical model has been developed to predict the effective thermal conductivity of the composite. Based on this model, a mathematical correlation between the effective thermal conductivity of the composite and the fiber content is developed. The results obtained from this correlation are in good agreement with the experimental data. This study explores the possibility of fabricating a class of epoxy composites with higher mechanical strength, superior insulation capability, improved glass transition temperature, and a low thermal expansion coefficient.
