“…The values are retrieved from the previous work conducted by the authors in [22]. Silicone rubber is found to have a higher tensile strength of ∼ 1.6 MPa and elongation at break of 600% than other metastructure absorber substrates, such as FR4 (tensile strength of ∼ 282 MPa and elongation at break of 1.95% [33]) and acrylonitrile butadiene styrene (tensile strength of ∼ 43.8 MPa and elongation at break of 7.2% [34,35]). The high ductility makes silicone rubber more suitable for a flexible matrix and it is easily moldable too.…”

One approach for lowering radar cross section (RCS) is by reducing reflection, which can be achieved by use of absorbers. Embedded meta-structure absorbers (MSAs) are void of metallic resonating structures, which minimize out-of-band reflections thus reducing the chance of detection by radar systems. Here, an X-band MSA is developed by embedding ionic deep eutectic solvent gel as subwavelength cuboidal resonant structures in flexible silicone rubber. The material properties and structural geometry of the gel combines to enhance the − 10 dB absorption bandwidth to more than 80 % . The fabricated Gel-Si MSA is sufficiently flexible with an overall thickness of ∼ 0.0775 λ 0 . 10 dB RCS reduction is evaluated in the range over the X-band. The RCS properties are insensitive to polarization angles up to ± 90 ∘ and incident angle up to ± 40 ∘ .

“…Moreover, several works on the mechanical reliability and behavior of polymers have been carried out [18][19][20][21][22][23][24] paying attention to rupture and failure of polymer structures to keep away from accidents causing production loose plus life damage of both human and material, besides saving money. Necar [25] studied the effect of temperatures ranging from -10 to 70 ° C on the mechanical properties of CPVC. They found that the yield strength and the elastic modulus decrease linearly according to temperature.…”

Most Chlorinated Poly Vinyl Chloride (CPVC) resins contain 63-69 % chlorine, in particular those used for the extrusion of plumbing tubes, due to this chlorination of basic PVC, CPVC offers a mixture of corrosion resistance and low installation costs for its main applications requiring service in non-ambient conditions. CPVC replaces copper owing to its economic gain and by virtue of its pressure resistance characteristics. In this article, we have been interested in fracture analysis and damage modeling of CPVC tubes by subject CPVC samples to burst pressure tests. We performed a set of burst tests on virgin and artificially damaged CPVC pipe at different notch lengths, then submitted the specimens to burst pressure tests, in addition to recording the pressure and time during these tests for use in conducting the study. The results of the burst tests were exploited to estimate the damage and reliability of the material, these two parameters allow us to follow the degradation of the pipes used; subsequently, we determined a new relationship between these two parameters through the fraction life. This makes it possible to predict the moment of damage acceleration and to intervene at the right time for engaging predictive maintenance.
