The bio-loading of materials is a research axis that has been very well studied in recent years in order to meet the needs of industrialists, the requirements of regulations, environmental constraints and sustainable development, unlike classical loads having a harmful effect on the environment in addition to their high density and high cost. In this numerical modeling, we studied the mechanical behavior of Nylon PA66 reinforced by Argan Nut Shell particles (ANS) using the Finite Element method in comparison with the Mori-Tanaka model. The numerical modeling results show that these particles are rigid elastic having a Young's modulus of 8150 MPa and a stress at break of 244.5 MPa. The reinforcement of Nylon PA66 by ANS particles has better elastic properties compared to the pure state. Young's modulus improves from 3282 MPa to 3950 MPa by the finite element method and 3853.6 MPa by the Mori-Tanaka model. The stress at break also improves from 98.46 MPa to 118.5 MPa by the first method and 115.6 MPa by the second model. The study of the different parameters on the final behavior of the bio composite shows that the mechanical characteristics of the bio composite become more optimal by adding more particle content (Wt%) at an optimal value of 20 Wt% and by decreasing the Argan Nut Shell particles size. This bio load of natural origin will therefore be considered as an alternative for classical loads in order to obtain an environment friendly eco composite with much better mechanical properties.

“…Te honeycomb structures are supposed to be used in lightweight, safe, and optimum energy utilization under quasi-static and impact loadings. Tese bionic tubes have several cross-sections such as a triangle, square, and circular, with numerous materials such as steel, aluminium [3], and composites [4,5]. Due to their unique mechanical properties, honeycombs are used in aircraft wings, foor panels, rudders, jet engine shells, wind turbines, and vehicle crash boxes [6].…”

The 2.5D (2.5-dimensional) structures are acquired to enhance safety and lightweight designs with better energy absorption in the aerospace and automobile sectors. Additive manufacturing (AM), which is practical to build suitable components in industrial and transportation applications, may produce these structures more efficiently. The current study aims to improve the 2.5D infilled structures mean crush force (MCF) and energy absorption capabilities. Under compression loading, the proposed novel nature-inspired 2.5D infilled structure is compared to six existing 2.5D geometries that are inspired by nature. These structures are made of cylindrical shells that are filled with various infill configurations and maintained at a consistent volume. Photopolymer resin is used as the material for the structures, which are created using a digital light processing (DLP) method under AM technology. The characterization of the constructed models was done under compressive out-plane quasi-static stress conditions. ANSYS numerical simulations have been carried out to confirm the dependability of experimental data. The impact of supporting ribs and infill designs on crushing behaviour is thoroughly discussed. Mean crush force (MCF) and specific energy absorption (SEA) under quasi-static compression loading are provided to the proposed unique nature-inspired 2.5D infilled structure to significantly boost crushing qualities, axial collapse, and energy absorption behaviours.

Modern research focuses on natural, green, and sustainable materials that can be used to replace conventional materials. Because of their beneficial qualities, natural fibre composites are being thoroughly researched. This research focuses on the development of a flax fibre reinforced with phenol-formaldehyde resin hybridization with ramie fibre through a vacuum infusion process. Eight different sequences were fabricated using a core–sheath structure and were mechanically characterized as per ASTM standards. The fabrication technique influences the adhesion of the matrix with reinforcement. The results also reveal that composite having ramie as a sheath layer and flax as a core delivers good mechanical characteristics compared to vice versa. The laminate H exhibited highest mechanical properties among all the eight laminates produced for this study. It exhibited a tensile strength of 54 MPa, tensile modulus of 0.98 Gpa, elongation of 7.1%, flexural strength of 143 Mpa, and compressive strength of 63.65 Mpa. The stress strain curves revealed that all the laminates exhibited ductile behaviour before failing during the tensile test and flexural test, respectively. The stacking sequence of the laminate H influenced the mechanical properties exhibited by it and its counterparts. A morphological study was carried out to analyse the failure surfaces. Morphological analysis exhibited few defects in the laminate after the tests. The composites developed delivers better mechanical properties than commercial composites available on the market, which can be used in lightweight structural applications.
