“…Isto confere ao animal a capacidade de não apenas converter-se em uma bola, mas também a possibilidade de alongar e comprimir além dos limites de sua carapaça rígida. Posteriormente Rashidi et al (2019) iriam demonstrar uma aplicação disto explorando geometrias circulares fechadas através de variações de aplicações entre materiais flexíveis e rígidos. A figura 1 mostra o detalhe das bandas.…”

The article presents the development of four models of natural systems made through digital materialization to serve as physical material for the application of Bionics and Biomimetics in product development. This is theoretical-practical research on the structures of natural systems and the development of the construction of physical models through digital printing. Application of the biological process called overlapping or overlaying, the term refers to the logic of overlapping "layers" as happens in animals such as the armadillo. The models of the bands of the armadillo, the honeycomb, the snowflake and Furnarius rufus nest will serve to be applied in project disciplines in the Product Design course as an opportunity to visualize and understand the relationship between shape and function present in natural systems. The material was produced at the FabLab Pronto 3D at the Federal University of Santa Catarina.

“…In another recent study, Rashidi et al [70] successfully demonstrate how a structure built with a composite material through additive manufacturing and with a design inspired on the armadillo (order Cingulata) carapace allows the design of high strain articulating cylindrical shells for aerospace applications. The composite material mimics the interaction of the soft collagen and rigid bone structure in alternating sections, with two 3D printing materials of Young moduli and Poisson ratios of 1 MPa and 0.48 and 2 GPa and 0.35, respectively.…”

Biomimetics and Composite Materials toward Efficient Mobility: A Review

et al. 2021

The development of new materials has always been strictly related to the rise of new technologies and progressively efficient systems. However, cutting-edge materials might not be enough to ensure the effectiveness of a given product if the design guidelines used do not favor the specific advantages of this material. Polymeric composites are known for their excellent mechanical properties, but current manufacturing techniques and the relatively narrow expertise in the field amongst engineers impose the challenge to provide the most suitable designs to certain applications. Bio-inspired designs, supported by thousands of years of evolution of nature, have shown to be extremely profitable tools for the design of optimized yet structurally complex shapes in which the tailoring aspect of polymeric composites perfectly fit. Bearing in mind the current but old-fashioned designs of auto-parts and vehicles built with metals with little or no topological optimization, the present work addresses how biomimicry is being applied in the mobility industry nowadays to provide lightweight structures and efficient designs. A general overview of biomimicry is made regarding vehicles, approaching how the use of composite materials has already contributed to successful cases.

“…Bio-inspirations are transformed into technologies such as bullet trains in locomotion, sustainable buildings based on termite house architecture, bio-decorations focusing on ergonomic and aesthetic designs, self-healing materials in sutures, surfaces derived from shark skin to efficiently overcome deep-sea tides, and adhesion aspects derived from amphibians, to name a few. Recently, bio-inspired design structures are identifying many applications such as aerospace [ 2 , 3 ], the automotive sector [ 3 , 4 ], as well as biomedical fields [ 5 ]. Rudraksha, with its scientific name Elaeocarpus ganitrus , has unique features to protect its seeds from damage due to mechanical or thermal loads [ 6 ].…”

Biomimicking Nature-Inspired Design Structures—An Experimental and Simulation Approach Using Additive Manufacturing

et al. 2022

Whether it is a plant- or animal-based bio-inspiration design, it has always been able to address one or more product/component optimisation issues. Today’s scientists or engineers look to nature for an optimal, economically viable, long-term solution. Similarly, a proposal is made in this current work to use seven different bio-inspired structures for automotive impact resistance. All seven of these structures are derived from plant and animal species and are intended to be tested for compressive loading to achieve load-bearing capacity. The work may even cater to optimisation techniques to solve the real-time problem using algorithm-based generative shape designs built using CATIA V6 in unit dimension. The samples were optimised with Rhino 7 software and then simulated with ANSYS workbench. To carry out the comparative study, an experimental work of bioprinting in fused deposition modelling (3D printing) was carried out. The goal is to compare the results across all formats and choose the best-performing concept. The results were obtained for compressive load, flexural load, and fatigue load conditions, particularly the number of life cycles, safety factor, damage tolerance, and bi-axiality indicator. When compared to previous research, the results are in good agreement. Because of their multifunctional properties combining soft and high stiffness and lightweight properties of novel materials, novel materials have many potential applications in the medical, aerospace, and automotive sectors.
