In recent times, demand for light weight and high strength materials fabricated from natural fibres has increased tremendously. The use of natural fibres has rapidly increased due to their high availability, low density, and renewable capability over synthetic fibre. Natural leaf fibres are easy to extract from the plant (retting process is easy), which offers high stiffness, less energy consumption, less health risk, environment friendly, and better insulation property than the synthetic fibre-based composite. Natural leaf fibre composites have low machining wear with low cost and excellent performance in engineering applications, and hence established as superior reinforcing materials compared to other plant fibres. In this review, the physical and mechanical properties of different natural leaf fibre-based composites are addressed. The influences of fibre loading and fibre length on mechanical properties are discussed for different matrices-based composite materials. The surface modifications of natural fibre also play a crucial role in improving physical and mechanical properties regarding composite materials due to improved fibre/matrix adhesion. Additionally, the present review also deals with the effect of silane-treated leaf fibre-reinforced thermoset composite, which play an important role in enhancing the mechanical and physical properties of the composites.

Synthesis of Graphene oxide (GO) was done by Improved hummer's method and confirmed by Field Emission Scanning Electron Microscopy, Transmission Electron Microscopy, Fourier Transform Infrared Spectroscopy, X-ray Diffractometry and Raman Spectroscopy. The dispersion of GO was obtained using cetyl trimethyl ammonium bromide (CTAB), a cationic surfactant, in the epoxy matrix. The enrichment in the mechanical properties was observed by loading of GO (1.0 wt.%, 2.5 wt.% and 5.0 wt. %) in the epoxy/coir fiber (ECF) composites. The ECF composites were prepared using hand layup technique, with constant fiber ratio of 5.0 wt. % and fiber length in the range of 5-7mm. The highest tensile strength of 13 MPa was obtained for 5.0 wt. % GO-reinforced ECF as compared to 4 MPa for neat epoxy and 6 MPa for ECF. Flexural strength of 64 MPa was obtained for 5.0 wt. % GO reinforced ECF as compared to 23 MPa for neat epoxy and 32 MPa for ECF. The impact strength increased from 31J/m to 44J/m and 135J/m for neat epoxy, ECF, and 5.0 wt. % GO reinforced ECF respectively. It was noticed that the CTAB treatment resulted in proper interaction of GO with epoxy resin and coir fibers, which improved mechanical properties of ECF.

“…Graphene is a basic building block of graphitic materials having all dimensionalities and used to fabricate/prepare varieties of composite/blend films and polymer nanocomposites. It has extraordinary mechanical [12,13], thermal [14,15], high specific surface, excellent aqueous processability, amphiphilicity and surface functionalizability [7,16,17] and hence extensively investigated for applications in many technological fields [18][19][20][21][22][23][24].…”

Shape memory polymers (SMPs) are the new class of smart fascinating polymer materials with different potential applications. This research work aims to present systematic investigations of electrically actuated shape memory (EASM) properties at different electric voltage of epoxy polymer filled with 0.1 to 0.4 wt. % of Graphene (GO) to develop SMPs nanocomposites. EASM effect and surface morphology functional analysis of composites were observed after EASM characterization by Field Emission-Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infrared Spectroscopy (FT-IR). 0.4 wt. % addition of GO showed highest shape recovery at 180 S, 140 S and 95 S for 40 V, 60 V and 80 V respectively. These results suggest that GO could be promising materials for electrically actuated shape memory applications.
