“…1 The natural fillers have many advantages over synthetic fillers such as biodegradability, corrosion resistance, ease of availability, low cost, eco friendly and free from health hazards. [2][3][4] Even the natural fillers have several advantages over synthetic filler, the use of natural fillers in composites is very limited due to their high moisture absorption, low thermal stability, hard to process and quality variations. 5,6 The disposing of hazardous waste like waste tyre rubber, wood dust and broken ceramic tiles were possessed environmental issues.…”

Composites reinforced with landfill waste materials have find the applications in engineering materials and they can lead to reduce the environmental pollutions. Waste tyre rubber, broken ceramic tiles and wood particles are creating the environmental hazard to the surroundings. In particular, the recycling of used tyre rubber is highly challenging, but it has very good property to absorb the energy. The reinforcement of rubber as single filler in composite has the limitations in processing and applications. Hence, the above waste materials are incorporated to prepare the composite in the present work. The fracture toughness and shear strength of composites were evaluated and compared with other combinations along with pure epoxy specimen. In order to find the application of composite in dynamic conditions the vibration analysis were done. The presents of rubber decreased the fracture toughness and at the same time the incorporation of ceramic largely improved the fracture toughness of epoxy composite. The shear strength of composites increased with the addition of ceramic and wood particles. But the rubber particle has the great influence on the damping behavior of ceramic base epoxy composites. The addition of ceramic with the epoxy increased the natural frequency and decreased the damping factor. This can be compensated by the inclusion of rubber with ceramic in epoxy resin matrix. 15 wt % addition of rubber with ceramic and epoxy increased the natural frequency of 18.52% and damping factor of 288% than 5 wt % of rubber with ceramic and epoxy. The natural frequency and damping factor of ceramic and rubber based epoxy composite have the highest amount of all combinations and can be used for vibration applications to absorb the energy at high frequencies.

This study has investigated the effect of natural fibres such as kenaf, coconut and jute and their combination as reinforced in an epoxy polymer matrix natural fiber reinforced polymer (NFRP) on mechanical properties (impact, flexural, tensile strength and hardness), thermal stability, tribological properties and biodegradability. The raw fibres were chemically treated with 3% NaOH for 24 h, and 10 wt.% was blended in the epoxy matrix. Further, a composite surface morphology and fibre dispersion were analysed using a scanning electron microscope. An improvement of an average of 30.39%, 1157.7% and 30.98% in impact strength, hardness and tensile strength, respectively, compared to pure epoxy composite. Further, the tribological study has shown a lesser frictional coefficient (∼0.275) in hybrid NFRP than in other composites where EN31 Steel disc is used as the counterbody. Moreover, the mixed NFRP has demonstrated excellent biodegradable properties compared to other NFRP and pure composites.
