“…Additionally, the majority of the interior sections of vehicles are made of plastic and other synthetic materials [5]. Te manufacturers adjust the approximate design of their vehicle's structure and add the required structural components that match the predominant design goals in order to meet the requirements of a specifc crashworthiness standard and fuel economy [8]. Te designer can alter structural elements like geometry while also modifying the material's characteristics by altering the orientation and volume of the fbers.…”

Natural fiber reinforced composite material has recently attracted interest due to its low density, low cost, acceptable specific characteristics, ease of separation, improved energy recovery, CO2 neutrality, biodegradability, and renewable nature. The goal of this paper is to design and construct a three-wheeled Bajaj door panel using composite materials reinforced with bamboo fiber. Design, manufacture of the component, and experimental techniques are used to meet the goals given. The bamboo plant is the raw material chosen for this thesis project. The matrix material (polyester resin) and hardener used in this investigation, as well as the woven bamboo fiber strip that has been used as reinforcement, were all obtained from local markets. Bamboo fiber that has been chemically treated with 5% NaOH and 95% purified water is used. Keeping in mind the needs of varied testing conditions and characterization standards, polyester resin and E-glass fibers were simply stirred together by hand for 15 minutes. The mixture was then put into the molds. In three distinct orientations (0°, 90°, and 0/90°), composite samples of bamboo fiber were created. In order for the part to respond to axial loads, shear loads, and side loads, it may need 0°, 45°, and 90° plies, respectively. The paper model’s 0° orientation was chosen in accordance with the findings of the samples’ analysis. Due to the direction of the applied load, it affects the strength design requirements. Based on the findings of the experimental data examination, it was determined that the respective values for tensile, compression, bending, and water absorption were 160 MPa (0°), 2709.2 MPa (90°), 110 N (0/90°), and 4%, respectively. The geometric model of the door panel on the three-wheel Bajaj vehicle’s door was designed. Based on these findings, it is suggested that the new exterior structural car door panel of the three-wheel Bajaj Compact 205 model be made of composite materials made of bamboo fiber reinforced with polyester and having strength of 160 MPa.

“…As an important support plate in the door, the inner panel can be used to fix various door parts on the one hand, and on the other hand, it also influences the overall rigidity, mass and intrinsic frequency of the door. The inner plate of the door generally adopts a thicker thin plate, 30 and the inner plate often stamps out a variety of stiffeners, in order to improve the overall rigidity and reduce vibration noise.…”

In this paper, a biomimetic optimizing design of the stiffeners layout of the automotive inner door panels is proposed based on vein unit of dragonfly wing. The distributions features of the dragonfly veins and similarity as stiffeners are analyzed, and then the excellent structural features of mechanical properties of the dragonfly veins are extracted to work as a biomimetic design. In order to research the distribution of the reinforced areas in the interior door panels under various operating conditions, the finite element model is established firstly. Secondly, gray relation theory combined with analytic hierarchy analysis are imposed to determine the weight value of each condition in multi-objective topology optimization to fully consider both objective and subjective factors, and topological optimization results indicate that the stiffeners of the inner door panel are biconically designed. Finally, the original finite element results of the inner door panels are compared with that after optimized with biomimetic stiffeners under the same operating conditions, and the result of the comparison verify the effectiveness of the biomimetic topology design. Specifically, for the dent-resistant and sinking condition, the strength of new door increases by 20.2% and 14.3%, respectively. Therefore, doors with biomimetic stiffeners have an increased resistance to deformation and vibration, while the mass is reduced by 2.7%. The results can provide valuable new ideas for the optimal biomimetic design of automotive door inner panel stiffeners.

“…Connection between the inner and outer part is made by mesh connection in the contact areas. The bases for the analysis are the established static load cases [2][3][4][5][6][7] to determine the longitudinal, transversal and torsional stiffness. The hood is bended in cases of the lateral and transversal stiffness tests and distorted in the torsional stiffness test.…”
