“…When worn in the mode of structural and energy adaptation of the friction surface, the sub-relief of the friction surfaces is covered by secondary structures of its type and is caused mainly by the presence of smoothed areas. The sub-micro-roughness of the patches is negligible [31][32][33][34].…”

The original test results of abrasive wear resistance of different type of construction polymer materials were presented and discussed in this article. Tests were made on an adapted test stand (surface grinder for form and finish grinding). Test samples were made of different types of polymer board materials including RenShape®, Cibatool® and phenolic cotton laminated plastic laminate (TCF). An original methodology based on a grinding experimental set-up of abrasion wear resistance of polymer construction materials was presented. Equations describing relations between material type and wear resistance were presented and discussed. Micro and macro structures were investigated and used in wear resistance prediction.

“…For higher angles, the structure was capable of withstanding the impact. In 2018, Nam et al [113] designed and fabricated a space shield system (using aramid and epoxy composite) fitted with an electromagentic-wave absorption system for stealth. The hyper-velocity impact tests of this shield were done using a two-stage gas gun shooting projectiles at velocities in the range of 2.7 to 3.2 km/s.…”

Safety of satellites as well as spacecrafts during space missions is a primary objective to preserve the physical and virtual assets onboard. Whipple shields belong to the class of protective equipment provided on the surface of the spacecrafts and satellites, to sustain impacts from the ultra-high speed debris, which can otherwise cause considerable damage to the corresponding structures. Recent works on whipple shields are focussed on determining the response of different geometrical arrangements and material properties under hyper-velocity impact at projectile speeds of 3-18 km/s. Advances in the whipple shield design include integrated and mechanised models employing high performance materials like fiber-metal laminates ensuring better operational capability. The forward bumper of the whipple shield is the first line of defence as it regulates the state of projectile after the primary impact. Use of aluminium alloys for front bumpers is popular, owing to their lightweight and strength characteristics. The advances for the front bumper have seen usage of ceramic, metallic foams, and super composite mixtures, which resulted in enhanced performance, durability and safety of the whipple shields. This work is a comprehensive coverage of the latest materials used for whipple shields, their performance characterization—both experimental and theoretical, and applications.

T HIS REVIEW presents the significance of nanotechnology as a new tool in textile printing to introduce multifunctional properties. Nanostructures, such as nano-fibers, nano-coatings, nano-finishing and nano-composites, have potentially revolutionized the textile manufacturing industry with high performance characteristics, such as electrically conductivity, self-cleaning, hydrophobicity or hydrophilicity, flame-retardant, antimicrobial properties and ultraviolet protection, as well as improving their printing performance, without changing the bulk properties of the coated fabrics. There are various techniques have been applied to explore the properties of the coated fabric surface, including scanning electron microscopy (SEM), atomic force microscopy (AFM), transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), Fourier-transform infrared spectroscopy (FTIR) and scanning probe microscopy (SPM).
