Special Issue Information

Dear Colleagues,

The implementation of innovative functional materials in the modern manufacturing industry plays an important role in sustainability. A central question is how to design and manufacture the novel functionalities or mechanical properties that are beyond the current materials. Nature’s solution to extraordinary durability, sustainability and resilience is countless, and offers many opportunities to engineers and scientists who are interested in the development of new functional materials with unprecedented energy efficient, environmental adaptive and mechanical performance.

This Special Issue aims to provide an overview of the recent interdisciplinary work on sustainable bioinspired functional materials. In particular, we welcome papers that focus on the following areas:

1) The fundamental understanding of the design principles in natural materials and/or development of innovative materials for the built environment;

2) The advanced experimental and theoretical analyses of eco-friendly bioinspired functional materials in the modern manufacturing industry (e.g. additive manufacturing) with different applications;

3) The modeling of the mechanical response of sustainable bioinspired functional materials under complex loading conditions (e.g. multiaxial cyclic loading);

4) The monitoring of the effects of climate conditions on bioinspired functional materials with enhanced long-term adaptability and durability.

The reduction in CO2 emissions has become an important issue as global environmental problems have become more serious. The replacement of conventional petroleum- and mineral-derived raw materials for building materials with local plant-based resources is expected to reduce CO2 emissions. This study examined the possibility of using compression-molded boards made from plant-based resources as sound-absorbing materials in rooms. Among plant resources, few studies have conducted detailed measurements of the sound absorption properties of boards compressed from reeds. When measuring the normal incidence sound absorption coefficient, a material layered with a reed compressed board, wood fiber insulation, and an air layer showed a peak in the sound absorption rate at approximately 850 Hz. This indicates the potential to effectively absorb noise in the frequency band of human voices (500–1000 Hz). By changing the layering of multiple sound-absorbing materials, the presence or absence of an air layer behind them, and the installation conditions of the sound-absorbing materials, and then measuring the sound absorption rate, variations were observed in the sound absorption rate and the frequency at which the peaks were observed. This provides guidelines for material configurations that exhibit sound absorption at specific frequencies. Full article

The introduction of 4D printing has revolutionized the concept of additive manufacturing; it is a promising technology that can bring immense advantages over classical production and manufacturing techniques, such as achieving programmed time-varying structures and consequently reducing production time and costs. The rise of 4D technology is considered an evolution of 3D printing due to the introduction of the fourth dimension: time. This is possible thanks to intelligent materials that can morph into programmed shapes in response to environmental stimuli, such as temperature, humidity, water, and light. When appropriately combined, these properties open the door to numerous applications in the engineering industry. This paper aims to provide information on the shape-memory effect (SME). To this scope, exploiting an already verified methodology available in the literature, a programmed flexural deformation were analyzed, experimentally changing the geometric parameters constituting the specimens. Experimental data were then processed to derive equations linking curvature to various independent parameters (such as temperature and time) through a quadratic and linear combination of the variables. This study contributes to a better understanding of current 4D-printing concepts through a mathematical characterization of the SME and its dependencies. In the study of the SME, such a complete methodological approach (analytical, experimental, and numerical) is a first step towards the design of more complex, bio-inspired components that could bring, in the coming years, development of passive sensors characterized by a combination of geometric properties that exploit a wider SME operating range to detect any variation of a physical quantity.
