Mechanical, microstructural, and thermal characterization insights of pyrolyzed carbon black from waste tires reinforced epoxy nanocomposites for coating application

Abstract

Pyrolysis is a viable technique to convert waste tires into recyclable products, as the dumping of these scrap tires pose a serious environmental threat. In the present investigation, a detail methodology to fabricate and characterize the carbonaceous filler (in the form of nanocarbon black obtained from pyrolysis of waste tires) modified epoxy resin composites has been retrieved. The composites with varying carbon filler content (0, 5, 10, and 15 wt%) were fabricated using the manual hand lay‐up and compression molding techniques. The morphological analysis (field‐emission scanning electron microscopy test) revealed that the synthesized pyrolytic carbon black was in nanoscale and uniformly dispersed in the epoxy matrix. Various physical (density and water absorption), mechanical (tensile, compression, flexural, hardness, and impact), electrical and thermal (differential thermal analysis and thermogravimetric analysis) tests were done to completely examine the nanocomposite developed. We found that the 5 wt% of carbon black in epoxy resin exhibited the best mechanical properties and was complemented by the microstructural (scanning electron microscopy and X‐ray diffraction) tests analysis. High tensile strength and hardness than neat epoxy resin makes this composite a potential candidate for polymer coatings in automotive industries.

Experimental investigation on the mechanical and morphological behavior of Prosopis juliflora bark fibers/E‐glass/carbon fabrics reinforced hybrid polymeric composites for structural applications

“…Also, it can deal with some of the major issues such as biocompatibility, durability, and thermal stability and lead to successful green composites which would be very much essential in solving present world environmental problems. [1][2][3][4][5] In this research investigation, an effort has been made to reinforce Prosopis juliflora fibers (PJFs) with synthetic E-glass and carbon fabrics and to know their suitability as reinforcements with polymeric matrices. India being an agricultural hub is gifted with many natural resources, which would be derived from agricultural lands or from forests.…”
