“…[24][25][26] Extensive literature on natural fibers like jute, palmyra, and luffa confirms their suitability for commercial production of hybrid composites, effectively meeting industry requirements. [27][28][29] Single-layered natural fiber composites exhibit relatively lower mechanical characteristics compared to multi-layered hybrid composites utilizing different natural fibers. The fiber orientation within individual single-layered composites has a significant impact on the overall mechanical properties.…”

In today’s world, researchers are actively seeking the most suitable materials to meet the growing industrial demands. These materials need to possess specific characteristics such as lightweight nature, high strength, excellent mechanical properties, and environmental friendliness. Due to these requirements, relying solely on mono fiber composite materials is insufficient. Therefore, it has become necessary to incorporate different reinforcements into polymer matrices to achieve the desired mechanical properties. This study focuses on the fabrication of a novel hybrid composite using jute fibers, luffa fibers, palmyra leaf fibers, and AISI 303 (0.5 mm) wire mesh combined with epoxy resin. The fabrication process involved utilizing vacuum bagging techniques. To assess the mechanical properties of the hybrid composites, two wire mesh orientations (45° and 90°) and a total of 12 stacking sequences of jute/wire mesh/luffa/palmyra (J/W/L/P) were selected. The mechanical characterization of the hybrid composites included tensile, impact, flexural, and interlaminar strength tests. Furthermore, a dynamic mechanical analyzer (DMA-8000) was employed to investigate the elastic behavior, including storage modulus (E′), loss modulus ( E″), and damping factor (tan δ). Additionally, the fracture surface's microstructure was examined using a scanning electron microscope (SEM). Among the various stacking sequences and fiber orientations, the 45° fiber orientation and the stacking sequences JWLP, JLWP, JWPL, JPWL, PWJL, and PJWL exhibited superior ultimate tensile strength. Notably, the PWJL stacking sequence displayed the highest average tensile strength (74.83 MPa), flexural strength (131.60 MPa), percentage elongation (1.35%), and interlaminar strength (1.47 kN). Moreover, dynamic mechanical analysis revealed that the hybrid composite sample with 90° wire mesh orientation exhibited a peak energy absorption of 0.820 at the transition region, specifically at a frequency of 0.5 Hz.

In this work the parametric evaluation of the influence of the dimensional variation of the arc height of a leaf spring on the energy dissipation and deformation energy is presented. With the use of the finite element package Abaqus, the cyclic force-displacement curve of the leaf spring under a compression test was numerically obtained through a discrete model for four cases, by varying the arc height of the spring, subsequently the energy dissipation and the potential energy was calculated. The discrete model was experimentally validated by performing compression tests on a commercial spring. The obtained results show that varying the arc height influences the amount of energy dissipation and potential energy. It was observed that by decreasing the arc height by 33%, the energy dissipation increased by 50% and the potential energy by 3%, resulting in an increment in the specific damping capacity of 47% with respect to the original model. From the discrete model, it is concluded that the contact pressure, contact area, and slip zones are more uniformly distributed when the arc height is reduced by 33%, besides of a decrease in the mass of the spring, results which may be useful for car suspension designers.
