“…Further the abrasive wear rate increases with the increase in flyash content but still it was less than the virgin nylon-66. This might be attributed to the combination of evidence such as the in-terfacial adhesion of the filler between matrixes [22] . This is associated with the increase in heat distortion temperature due to the filler content, and the ability of flyash to reduce the thermal softening of the polymer due to the interfacial heat developed during sliding.…”

In the current study, the effect of flyash (FA) on the physic-mechanical, electrical, thermal and morphological behavior of nylon-66 (PA) was investigated. PA/FA composites were prepared by melt mixing via twin screw extruder, with varying weight percent (5 wt %, 10 wt %, 15 wt % and 20 wt %) of flyash. The results of composites were optimized and compared with virgin nylon-66. Mechanical and electrical properties of composites improved up to 10 wt% of FA loading without compromising the properties. The flyash filled nylon-66 composites showed a low abrasive wear rate. Increase the heat distortion temperature of composites with an increase in weight percent of flyash while opposing the melt flow rate. Flyash filler enhances the stiffness of plastics but significantly reduces the impact properties. Dispersion of flyash was examined by impact fracture surface of composites using a scanning electron microscope.

“…The testing was conducted at a speed of 500 mm/min at room temperature. The various tensile properties like moduli at different percent elongation, tensile strength (TS) and elongation at break (EB) were generated from the tensile curve [24,25] . The hardness of the cured slabs was measured by a multi-unit hardness tester (MUHT) as per ASTM D2240.…”

Natural rubber (NR) is not only the main compounding ingredient used to make the majority of components of tires as well as other rubber products, as it plays a significant role in ensuring that they operate well and complies with environmental standards. The applications of NR products are limited to high temperatures due to the revision tendency of NR vulcanizate. To address these issues, the potential engagement of a carbon black (CB) coupling agent (CA) in the presence of metal oxide i.e. Zinc Oxide (ZnO) was investigated in an NR-based system. This CA has dual functionality on physicomechanical properties. CA has the ability to reduce hysteresis loss as well as improve anti-reversion properties and these properties thoroughly depend on the presence of ZnO. While ZnO was added to the master formulation, a 65% improvement in reversion properties was observed. On the other hand, while ZnO fully transferred to the final formulation, bound rubber (BR) content increased by 19%, the difference in storage modulus (ΔG’) is reduced by 22%, cure rate index (CRI) improved by 14%, loss tangent (tan δ) reduced by 18% and slightly improve in elongation at break compared to control compound. Thermo-gravimetric analysis (TGA) was engaged to understand the thermal stability and degree of purity of CA. A differential Scanning Calorimeter (DSC) was used to detect the phase transition of CA. Fourier Transform Infrared Spectrum (FTIR) was adopted to detect the presence of carboxyl and amine groups in the CA moiety. Payne effect, BR content and Transmission Electron Microscope (TEM) were employed to investigate the micro-level dispersion of CB in the natural rubber (NR) matrix.

Throughout history, wood has been recognized as one of the most ancient construction materials. Wood material is used in a wide variety of fields due to its many positive properties. Despite its extensive use and distinct characteristics, it does have certain weaknesses, particularly in terms of being relatively brittle, especially under bending forces. To enhance its performance and reinforce wooden structural components, a viable solution is to incorporate FRP (Fiber-Reinforced Polymer) components, which are commonly utilized in rehabilitation processes. The versatility and ease of application with various materials like concrete, wood, and steel have facilitated the enhancement of structural elements' strength and ductility. In recent years, fiber-reinforced polymers have been widely used to strengthen wooden structures. In this study, the effect of FRP reinforcement number on the bending properties of glulam beams obtained from chestnut tree species was investigated. Chestnut beams were reinforced with 1, 2 and 3 layers of FRP. The beams were subjected to the bending test. After the bending test, the maximum load carrying capacity, bending strength and modulus of elasticity values were examined. Obtained findings showed that flexural properties increased with strengthening. In addition, with the increase in the number of reinforcements, the maximum load carrying capacity, modulus of elasticity and flexural strength values increased.
