“…It is found from the literature that the wt.% of marble dust varying from 0 to 24 directly influences the thermal conductivity of the composites. 21 Consequently, composites B2 and A2 showed higher thermal conductivities. But, in between them composite B2 showed better performance due to the presence of glass fibres in it.…”

Environmental awareness brings the attention towards the biodegradable natural fibre composites in most of the industrial and manufacturing sectors. The light weight, low cost, ease-in-availability, biodegradability and non-toxic inherited nature of natural fibres have predominated over the synthetic fibres. Jute hybrid composites are very common from the early decades for their superior mechanical performance. In this research work, the woven form of natural fabric like jute and sisal has been hybridised with synthetic S-glass fabrics have been reinforced in epoxy matrix by most convenient and economic hand layup process. The nano-marble dust, the waste of marble industry was used as filler in the hybrid composites. The natural fabrics are mercerised before fabrication for improvement in fibre texture in order to get better interfacial bonding, as waste materials, wax, lignin contents and other foreign ingredients are removed by the process. The various characteristics such as physical, mechanical and thermal are studied for the prepared composite specimens. It is observed that the tensile strength of the composite improved drastically due to the presence of nano-marble dust. The impact strength is also enhanced due to the addition of nano-marble dust and more no. of glass fabric layers in composite. Thermo-gravimetric analysis (TGA) revealed that the composite containing nano-marble dust and glass fibre mat exhibited maximum degradation temperature of 410.4°C.

“…This improvement in tensile strength retained up to 20 wt% and after that reduced, which speci ed that the superior stress transfer takes place between ber and epoxy for optimum ber reinforcements (Rashid et al 2016). The decrease in tensile strength above 20% was because of the poor wettability between polymer and bers as the inadequate ow of polymers occurs around the bers (Pankaj et al 2021) Flexural strength testing…”

This paper discusses on fabrication, testing and evaluation of delamination factor of nettle fiber based composites for low duty applications. The randomly oriented nettle fibers were used to fabricate the biocomposite by conventional hand lap up technique. Epoxy and Nettle based composite plates were developed by varying fiber weight percentage from 5% to 25%. The flexural, tensile, impact, chemical resistance and water absorption rate of developed nettle fiber based biocomposite were examined for different fiber weight fractions in the randomly oriented patterns as a unique and innovative attempt. During the investigation, flexural strength and tensile strength were improved up to 20 wt% of fiber addition and then it was decreased. This resulted in a continuous rise in impact strength with an enhancement in fiber wt. %. The influence of fiber weight percentage on water absorption and chemical resistance of fabricated composite was examined in different environments. The result showed that the nettle fibers can be used as an essential reinforcing material to design and fabricate mechanical and structural members for low duty application. The chemical behavior of nettle based composite was studied by the FTIR spectroscopy method and the presence of chemical functional group was confirmed. The drilling behavior of developed nettle/SiC/epoxy hybrid composites was evaluated by consider cutting process parameters like feed rate (0.125, 0.212 and 0.3 mm/rev), spindle speed (400, 600, 800 rev/min) and drill diameter (4, 6, 8 mm). Analysis of variance was used in designing experiments for the current investigation. Feed rate was found to be a very impressive factor in influencing the delamination factor.

Brake pads are vital parts of automobiles, where tribological properties are prime concern. Usually, asbestos brake pads were used, which were replaced by copper-based in later years. As brake lining materials have evolved, synthetic friction composites were explored as alternatives. Recent works suggest that, natural composites are promising friction material. However, poor thermal conductivity and frictional stability have limited their applications. Surface treatment of fibers and addition of secondary fillers have improved their possibilities. Thus, hybridization of reinforcements has expanded their range of applications. The present article attempts to review various aspects of brake pads and their testing with attention on natural composites. Their properties were studied to conform their ability to meet desired requirements. The article reviews the studies conducted in recent years on various materials properties related to brake pads. The future potential of natural components in the development of friction composite materials for automotive applications is highlighted.
