“…Multifunctional materials are designed such that they combine two or more functions that are typically accomplished using separate materials or systems into a single material. The most common structural multifunctional materials over the past decade have focused on incorporating self-healing, [1][2][3][4] energy harvesting, [5][6][7][8] sensing, [9][10][11] and health monitoring [12][13][14][15] into the structure. For example, the integration of nanoscale piezoelectric materials in continuous fiber reinforced polymer composites have allowed for structural components to harness wasted kinetic energy from mechanical vibrations in aerospace and automotive applications.…”

Composite materials designed for ballistic applications typically require fiber-matrix interfacial properties which are considerably different than those used in more common structural applications. Ballistic composites are usually benefited through the use of a weaker interface that allows the high This article is protected by copyright.

Here, the multifunctionality of a zinc oxide (ZnO) interphase through a tailored interfacial shear strength (IFSS) as a function of strain rate is demonstrated. Both zinc oxide (ZnO) nanowires and nanoparticles are shown through variable strain rate pullout to enable tailored behavior with the nanowires producing an 87% increase in IFSS over untreated fibers under quasi-static loading, and 53% lower interfacial shear strength than untreated fibers at 2200 s-1. The reduced interfacial strength under dynamic loading conditions is attributed to the the polymer's viscoelasticity, as matrix stiffening effects reduce the nanowires' functional gradient, causing brittle failure of the ceramic interphase. The results demonstrate the potential for ZnO nanowires and nanoparticles to enable the tailored design of interfaces and to realize multifunctional materials with optimal behavior under both static and dynamic loading conditions.

In order to obtain thermal barrier coatings by Suspension Plasma Spraying (SPS) process with potential new self-healing ability multicomponent submicronic Y-TZP/Al2O3/SiC suspensions were prepared. For this purpose, concentrated aqueous suspensions of individual components as well as the multicomponent mixture were studied and characterised in terms of colloidal stability and rheological behaviour to determine the best conditions for processing and preparation of the coatings. In the study, different dispersant contents and sonication times were tested. Subsequently, low concentrated suspensions were prepared to obtain preliminary thermal barrier coatings with the optimised feedstock. Thus, ceramic coatings were deposited by SPS and then characterised in order to assess the microstructure and phase distribution, in particular, the degree of preservation of the sealing agent, SiC, in the final coating as a previous indicator of its self-healing ability.

“…One of the applied applications of self-healing materials can be in the area of automobile sectors in the form of self-healing paints. The development of light weighted fiber-reinforced composites (FRCs) structures for weight reduction and self-healing coatings to prevent minor impacts and corrosion has a broad scope in aerospace industries (Bierwagen, 2001; Das et al, 2016; Heinz et al, 2000; Manuel, 2008). Different realistic strategies have been formulated in the past mimicking the capabilities to heal the polymer and metallic based composites.…”

In this article, the healing assessment of the AA2014 matrix reinforced with NiTi wires and solder alloy as healing agents is investigated through flexural testing. The idea of a smart composite was such that it could retain its structural stability through NiTi wires reinforced, which ultimately heals the macro cracks, whereas the solder alloy binds the micro-cracks by filling through the gap after heat treatment. The objective of this work is to determine the parameters influencing self-healing assessments. Specimens with different shape memory alloy vol% (0.5%, 1.3%), specimen size (1, 2) and shape memory alloy wires diameter (0.47 mm, 0.96 mm) were fabricated for analysis. Furthermore, Taguchi orthogonal columns of L8 (4^1 2^3) array technique was implemented to study the observations from different experimental runs. Healing temperature (i.e. 600°C) was selected such that it could take advantage of the compositional healing of the matrix. The completely damaged specimens through the bend test were thermally treated at different healing durations (30, 60, 90, 120 min) in a furnace to activate healing. The results show that a maximum of 96.95% of crack depth, 100% of crack width, and 73.76% of the recovery in flexural strength was recovered after heat treatment.
