“…9,10 Among various natural fibers, Sesamum indicum L. an oldest cultivated plant that grows annually up to a height of 40–80 cm can also give rise to cost-effective green composites. 11,12 Till now, no research has contributed to the fabrication of composites using Sesamum indicum L. as a reinforcement and recycled thermoplastic. There is an enormous opportunity for effective utilization of these by-products which are produced in large amounts every year.…”

Composites synthesized from natural waste and recycled plastic is quite a promising and interesting field for scientists and polymer industries. In the present study, bio-composites based on agriculture residue Sesamum indicum L. and recycled-low density polyethylene were synthesized by extrusion and injection molding technique at a fiber loading of 10–40 wt%. Additionally, 3% of maleic anhydride grafted low density polyethylene was used as a compatibilizer. The prepared composites were irradiated at 25 kGy, 75 kGy and 125 kGy doses of gamma rays. The effects of different fiber content and gamma doses on mechanical properties were studied statistically by Design Expert software. Response surface methodology was employed to depict the interaction among various factors and optimization was done by desirability index method. Findings indicated that composites having 30% Sesamum indicum L. irradiated at 125 kGy demonstrated best mechanical properties. A significant enhancement in tensile and flexural properties of irradiated composites can be explained effectively in terms of the cross-linking effect. The fiber–matrix adhesion and modifications in composite structure was characterized by fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and X-Ray diffraction (XRD) analysis. Furthermore, thermal stability of the composites was also found to be increased. In addition, gamma-irradiated composite exhibited the highest storage modulus and a decrease in mechanical loss factor was also observed.

“…In recent years, studies reporting the potential for insertion of lignocellulosic material particles in association with Pinus and Eucalyptus woods have been reported in the literature, such as coffee husks (Martins et al 2021); corn cob (Ramos et al 2021) and sesame stem (Legesse et al 2021). These studies showed that there is a large availability of lignocellulosic waste with potential for the production of particleboards, adding value to these wastes and diversifying the raw materials used.…”

The use of alternative raw materials to produce particleboards is an interesting strategy to add value to lignocellulosic biomass and diversify the forest products industry. The aim of this study was to evaluate the potential for using Mauritia flexuosa particles in association with Eucalyptus spp. wood for the production of particleboards. Prior to the production of the panels, the raw materials were evaluated for basic density and chemical composition. The panels were produced with particles of Eucalyptus spp. and Mauritia flexuosa in mass proportions of 100/0%, 90/10%, 80/20%, 70/30% and 60/40%, respectively. The quality of the particleboards was evaluated by water absorption and thickness swelling, internal bonding and static bending tests. As Eucalyptus spp. particles were replaced by Mauritia flexuosa, the panels showed less dimensional stability, due to the fact that the compression ratio increased due to the lower density of Mauritia flexuosa particles. The substitution of 1% of Mauritia flexuosa particles caused a reduction of 10.49 MPa for MOE, 0.09 MPa for MOR and 0.01 MPa for internal bonding. The results demonstrate that it is feasible to replace up to 17.5% of Eucalyptus spp. wood with particles from Mauritia flexuosa so that the panels have physical and mechanical properties appropriate to the marketing standards.
