The effects of carbon allotropes on the surface b 0.5 wt%, 0.75 wt% and 1.0 wt%, by weight percent of each type nanofillers. Experimental results revealed that FRC with 0.75% GO showed better surface and bulk properties compared to composites without any non-fillers. On the other hand, FG as nanofillers showed much enhanced strength and heat deflection while comparing with GO based reinforced composites. After optimal wt. % it was observed that the additions of nanofillers degrade the surface and bulk properties of the composite.

In this study, the effects of carbon allotropes on surface and bulk properties of flax fiber-reinforced composites (FFRC) are examined. Flax reinforced composites were prepared using two different nanofillers as FG & GO. Various surface and bulk properties like heat deflection, hardness, impact & tensile-strength & flexural-strength tests were performed. Addition of nanofillers like GO/ FG enhances the entire surface and bulk properties. Experimental values manifests that at 0.75 wt% of GO, the FFRC has better impact and tensile-strength, hardness, flexural-strength and heat deflection that is 30%, 15%, 18%, 20% and 13% respectively. But for FG as nanofillers, have manifested better properties when contrast to the GO and pure the FFRC. The properties like impact & tensile-strength, hardness, heat deflection & flexural-strength test are improved by 36%, 18%, 22%, 22% and 15% respectively. It was found that, after the addition of optimum weight % of nano-fillers, there was a degradation of surface and bulk properties.

With global advancement towards green technology, bamboo fiber has been treated as an extensive resource for eco-friendly living and competitive materials for industrial uses, due to their favorable characteristics such as durability, recyclability and promising mechanical properties. In this study natural fabric reinforced composites were prepared by bamboo fibers (BF) weave in a 1–1 (warp, weft) method by hand layup technique. There are three composition of composite prepared by varying the weight percentage of each nano-material with 0.5%, 0.75% and 1.0%. The various mechanical and thermal properties of prepared composites were compared by addition of two types of nanofillers: Graphene Oxide (GO) and functionalized Graphene (FG). The findings revealed that the incorporation of functionalized Graphene (FG) composites can be an effective approach in-term of mechanical properties as compared to pure and GO composite. From the experimental values it was clear that at 0.75 wt% of FG the Bamboo fabric reinforced composite shown better tensile strength, impact strength, hardness and heat deflection of 30%, 19%, 16% and 15% respectively. It was also observed that after optimal wt. % of nanofillers the mechanical properties are degraded by addition of nano-materials.

In this present study the mechanical and thermal properties of E-glass fiber reinforced composites was investigated. Composites filled with varying wt. % of Graphene Oxide (GO) and Carboxylic Functionalized Graphene (CFG) was prepared by mechanical stirring technique followed by hand layup method. There are three composition of nano-composite prepared by varying the weight percentage of each nano-material with 0.4%, 0.6% and 0.8%. The mechanical properties such as flexural strength, tensile strength, impact strength, heat deflection and hardness of the prepared nano-composites were studied and compared on various nanofillers. The findings revealed that the incorporation of functionalized Graphene (CFG) composites can be an effective approach in-term of mechanical properties as compared to pure and GO composite. The experimental value shown that at 0.6 wt% of CFG the E-glass fabric reinforced composite shown better flexural strength, tensile strength, impact strength, heat deflection and hardness of 30%, 39%, 22%, 12% and 20% respectively. It was also observed that after optimal wt. % of nanofillers the mechanical properties are degraded by addition of nano-materials.

Fiber-reinforced composites are mainly used in aerospace engineering automobile and structural applications. The present study focuses on structural applications. The elastic response of material deals with shape recovery effect of material whereas viscous response plays a vital role in dispersing mechanical energy. Dynamic Mechanical Properties of fiber-reinforced epoxy composites (carbon, Kevlar, hybrid and sandwich configurations) were assessed in the current study. Fiber composites were manufactured with a weight ratio of 60:40 with a hardener ratio of 10:1 using a hand layup technique. Dynamic mechanical response of composite samples was assessed against temperature and frequency sweep. It has been observed that the carbon-reinforced epoxy shows the least tan delta value i.e. 0.22 at a temperature of 111.06 as compared to other composites, indicating its superior elastic behavior; while Kevlar has shown better damping properties. The sandwich configuration (carbon-Kevlar-carbon) exhibited visco-elastic properties indicating its utility with tougher skin and its core with higher damping ability. The Tan Delta of sandwich configuration is 50% higher than that of carbon fiber composite and 15% lower than that of Hybrid fiber composite. This enables the sandwich configuration capable of taking loads on its skin, and more energy dissipation at its core.

The main agenda of writing this particular review is to study and understand the current situation and practices related to the various waste management steps taken in India for human development. On the other hand, we can even acknowledge some recommendations and suggestions to improve the waste management techniques in rural and urban areas of India. This review is mainly focused on secondary research. Ongoing reports which are based on improving the systems are studied which are mainly related to waste management techniques and recommendations of key industry experts or NGOs or government accountability agencies or planners or consultants. It acknowledges us about the different waste management techniques in India and helps us to find out the ways for improvement in the waste management for the human well-being. The review of this paper attempts and tries to understand the importance of the role played by the government and private sectors who are generally involved in the managing, the garbage of India.
