Abstract null null This study reports the electrical conductivity of multi-wall carbon nanotubes (MWCNTs) embedded copper nanocomposites. Copper-based nanocomposites are prepared by the powder metallurgy route method with two different secondary operations, (i) hot pressing and (ii) rolling. The MWCNTs doping weight percentage used are 0, 0.25, 0.5, 0.75 and 1 wt% of copper (or base material). The four-point probe technique is used to measure the electrical resistance of the prepared samples. Th...

Abstract Natural protection offered to living beings is the result of millions of years of biological revolution. The protections provided in fishes, armadillos, and turtles by unique hierarchal designs help them to survive in surrounding environments. Natural armors offer protections with outstanding mechanical properties, such as high penetration resistance and toughness to weight ratio. The mechanical properties are not the only key features that make scales unique; they are also highly flexi...

Abstract This study investigates the influence of textile layers on the uniaxial tensile performance of the basalt textile reinforced concretes (BTRCs). The tensile tests were conducted on BTRCs reinforced by three, four and six numbers of basalt textile layers. It was found that the textile reinforcement would enhance the tensile strength, ultimate strain, and total energy absorption of the BTRCs, but also reduced the first crack stress and strain of the cement matrix. Meanwhile, the formation ...

Abstract Textile reinforced concretes (TRCs) have many extraordinary features that make them a future-ready material exposed to complex environmental situations. However, current knowledge related to TRCs under mechanical loading and environmental conditions is not fully explored as compared to conventional fiber reinforced concretes. The present work investigates the quasi-static pullout performance of single-yarn and textile type (AR-glass and basalt fiber) reinforced cement mortars under diff...

In this study, a new biomimetic design of protective equipment has been proposed. Basically, teleost fish scales combine a two-layered structure, tuff high mineralized bony layer with relatively soft collagen and fiber-based sublayer arranged in periodic overlapping design, which offers excellent flexibility and puncture resistance. For the biomimetic design of fish scales, a hard-ceramic layer with ultra-high-molecular-weight polyethylene based-sublayer is used for the design of protective equi...

This study is focused on the drop weight low-velocity impact (LVI) response of glass woven polymer composite laminates reinforced with multiwall carbon nanotubes (MWCNTs). Symmetrical quasi-isotropic laminates with zero bending-extension coupling were fabricated. Six hundred-grams per square meter plain glass woven fabric was used as a primary reinforcing agent while MWCNTs were used as the secondary reinforcement. The exceptional mechanical properties of MWCNTs in the context of impact damage t...

Abstract Carbon nanotubes (CNTs) have been in use for a long time for preparation of polymer composites due their excellent mechanical, thermal, electrical, physical properties etc. Many industries including automobile, aerospace, sports and marine industries have been using CNTs as a multi-functional material for improving the overall properties of their prepared composites with a small amount of loading value. In this review, we list the mechanical properties of nanotube reinforced polymer com...

Abstract Underground mines offer various non-favourable environmental conditions, one among them is the presence of corrosive elements which are not suitable for conventional materials such as steel. This problem can be avoided to a certain extent by using glass reinforced polymer (GRP) rebars. GRP rebars show high tenacity and excellent corrosion resistance compared to conventional steel which extends these materials application to constructions roofing supporting and columns. Thus this paper a...

Abstract Strengthening of cement-based materials have been always challenging for research communities. The steel bars or cages are the classical reinforcing materials however the limited availability of metals in mother nature lead humans to find suitable alternatives for Cementous concretes. Textile reinforced mortars (TRMs) are the materials in which the strengthening of cement mortars is done with glass, Kevlar, polypropylenes, nylons etc. instead of using steel reinforcement. These syntheti...

This research work investigates the energy absorption, and damage tolerance behavior of three phased (carbon woven/epoxy/multiwall carbon nanotubes) polymer composites. Five doping weight fractions of multi-wall carbon nanotubes (MWCNTs) are considered as 0, 1, 2, 3 and 4 wt.% of thermosetting epoxy resins. Low-velocity impact (LVI) tests are conducted on drop tower setup with three different velocities, 3.5, 4.5 and 5.5 m/s. Damage caused by a 10 kg, hemispherical headed cylindrical impactor is...
