“…The first example is ultrasound fuel probe, which is an accurate indicator. An electrical stimulus piezoelectric is used to make an ultrasonic, and when the incident wave is reflected by surface of the liquid fuel, it is detected with a transducer piezoelectric sensor, thus the level of fuel can be exactly measured [154]. Second example is SMA-based wings or smart wings.…”

Smart materials are a family of materials that are listed in advanced materials. These groups of materials have self-accommodation with environment and they are classified according to their responses, such as physical (pressure, temperature, humidity, light, electric field, magnetic field), chemical (pH, CO2, etc.), or biological stimuli. The smart materials can convert the absorbed energy or their characteristics may undergo a change. Smart materials are getting high attentions due to their commercial applications in either actuator or sensor form. This work demonstrates an exclusive review of different types of smart materials with their specific characteristics, and some related investigations that improved smart material properties. In addition, the applications of smart materials are categorized according to the different application areas, such as medical implantation, reducing waste, and nano engineered systems.

“…A class of composite materials is classified as advanced composites which is defined by metal matrix composites, high-performance fibre-reinforced polymers, and those most used in high-performance aerospace vehicles, and their properties are the ceramic matrix composites. This class of composite materials provide supplementary functional advantages, the most highlighted being the temperature resistance [8,9]. Using composite materials in developing parts of aero vehicles implies more than just replacing the metals or other regular materials, it is about the introduction of advanced materials which have a role in a multitude of features starting from new designs in morphological structures, which were initially not possible with traditional materials [10].…”

Ceramic Composite Materials Obtained by Electron-Beam Physical Vapor Deposition Used as Thermal Barriers in the Aerospace Industry

This paper is focused on the basic properties of ceramic composite materials used as thermal barrier coatings in the aerospace industry like SiC, ZrC, ZrB 2 etc., and summarizes some principal properties for thermal barrier coatings. Although the aerospace industry is mainly based on metallic materials, a more attractive approach is represented by ceramic materials that are often more resistant to corrosion, oxidation and wear having at the same time suitable thermal properties. It is known that the space environment presents extreme conditions that challenge aerospace scientists, but simultaneously, presents opportunities to produce materials that behave almost ideally in this environment. Used even today, metal-matrix composites (MMCs) have been developed since the beginning of the space era due to their high specific stiffness and low thermal expansion coefficient. These types of composites possess properties such as high-temperature resistance and high strength, and those potential benefits led to the use of MMCs for supreme space system requirements in the late 1980s. Electron beam physical vapor deposition (EB-PVD) is the technology that helps to obtain the composite materials that ultimately have optimal properties for the space environment, and ceramics that broadly meet the requirements for the space industry can be silicon carbide that has been developed as a standard material very quickly, possessing many advantages. One of the most promising ceramics for ultrahigh temperature applications could be zirconium carbide (ZrC) because of its remarkable properties and the competence to form unwilling oxide scales at high temperatures, but at the same time it is known that no material can have all the ideal properties. Another promising material in coating for components used for ultra-high temperature applications as thermal protection systems is zirconium diboride (ZrB 2 ), due to its high melting point, high thermal conductivities, and relatively low density. Some composite ceramic materials like carbon-carbon fiber reinforced SiC, SiC-SiC, ZrC-SiC, ZrB 2 -SiC, etc., possessing low thermal conductivities have been used as thermal barrier coating (TBC) materials to increase turbine inlet temperatures since the 1960s. With increasing engine efficiency, they can reduce metal surface temperatures and prolong the lifetime of the hot sections of aero-engines and land-based turbines.

“…Both components contribute properties to the new composite material with enhanced overall performance. They represent an attractive alternative for metal replacement, as reinforced materials possess many unique properties that provide advantages in different applications (Zaman et al, 2013; Toozandehjani et al, 2018). The FRP materials usually combine required high-strength, stiffness, and light weight with low-cost, design flexibility, and assembly simplification (Fu and Lauke, 1996; Thomason and Vlug, 1996, 1997).…”

Automatic Fiber Length Measurements with a Multi-Stencil Fast Marching Method on Microscopy Images

et al. 2020

Fiber length has a strong impact on the mechanical properties of composite materials. It is one of the most important quantitative features in characterizing microstructures for understanding the material performance. Studies conducted to determine fiber length distribution have primarily focused on sample preparation and fiber dispersion. However, the subsequent image analysis is frequently performed manually or semi-automatically, which either requires careful sample preparation or manual intervention in the image analysis and processing. In this article, an image processing and analysis method has been developed based on medial axis transformation via the multi-stencil fast marching method for fiber length measurements on acquired microscopy images. The developed method can be implemented fully automatically and without any user induced delays. This method offers high efficiency, sub-pixel accuracy, and excellent statistical representativity.
