In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of par...

in this research, the effect of 2.3 wt.% aluminum addition on the microstructure and tensile properties of high manganese austenitic steel fe-18mn-0.6c was studied. for this purpose, the samples were investment cast, homogenized and hot rolled. tensile testing was carried out at ambient temperature. microstructural investigations and fractography on the steel samples were carried out using an o...

Mechanical properties are the attributes that measure the faculty of a metal to withstand several loads and tensions. In particular, ultimate tensile strength is the force a material can resist until it breaks. This property is one of the variables to control in the foundry process. The only way to examine this feature is to apply destructive inspections that make the casting invalid with the s...

PURPOSE To assess the effect of cyanoacrylate glue on knot slippage and strength in vitro. METHODS Ethibond 3/0 was tested using a tensile tester. A single drop of cyanoacrylate glue was applied to the knots. Seven knot configurations (10 samples each) were tested: (1) a surgeon's knot (S) plus 4 square throws (+4) without glue (control group), (2) S plus one square throw (+1) without glue, (...

The aim of the present study is to investigate the effect of variation of polypropylene fibres ranging from 0.1% to 0.4% along with 0.8% steel fibres on the behaviour of fibrous concrete. The mechanical properties of the concrete such as compressive and tensile strength have been investigated. The result shows that addition of polypropylene fibre has a little effect on the compressive strength,...

carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film, containing 0-10% cellulose nanowhiskers (cnw), was produced through casting method, while physical properties of the films being investigated. cmc-pvoh-cnw nanocomposites, were prepared with a diluted suspension of cellulose nanowhiskers. nanowhiskers suspension was prepared through acid hydrolysis of cotton linter by sulfuric a...

A Nd:YAG laser was used for joining a pseudoelastic Ti-51.5 at.% Ni shape memory alloy. Tensile tests on sheet metal of 0.5 mm thickness were performed at temperatures of -40°C, +20°C and 1 10°C, representing the martensitic, pseudoelastic and austenitic condition, respectively. Laser-welded specimens exhibited an ultimate tensile strength of about 820 MPa not affected by the test tempefature. ...

Background: The effect of in vivo implantation on breast implants is important to both physicians and patients, but little information about the in vivo aging process of silicone gel-filled breast implants has appeared in the literature. The effects of the in vivo aging process could affect the durability of breast implants. Objective: The purpose of this study was to investigate changes in the...
