    This study is to investigate the fatigue life of high speed rail in Malaysia. This paper describes about the experimental and simulation analysis investigation on fatigue life of rail profile UIC 54 using bulk specimen according to ASTM E 466-15 standard. The Fatigue life testing was performed in the fatigue testing machine (Instron 8800) 100 kN. Meanwhile, the fatigue life analysis was performed in ANSYS Workbench 14.5. Furthermore, the stress levels for experimental testing were applied as 16.7%, 25%, 35%, 50%, 58.3%, 66.77% and 75% with machine frequency of 20 Hz. Apart from that, the total fatigue life cycles for rail profile UIC 54 were acquired from both experimental and simulation. The fatigue life S-N curves were plotted and validated with the results of the simulation analysis with experimental results.

    Rubber composites are often used at high temperatures, particularly in practical applications, such as autoclave components, gaskets, and seals. This study investigated the effect of elevated temperatures on the friction and wear properties of pineapple leaf fiber (PALF)-reinforced natural rubber (NR) composites with the addition of multi-walled carbon nanotubes (MWCNTs). Commercial NR composites were prepared using a two-roll mill mixing method, followed by molding. The PALF and MWCNTs contents were fixed at 30 and 10 parts per hundred rubber (phr), respectively. The frictional force, coefficient of friction (COF), and specific wear rate (SWR) were studied in the temperature ranges from room temperature (RT) to 80°C under various applied loads (5, 10, and 15 N). A significant improvement in the wear properties of the composites was achieved with increasing temperature. The results showed that the inclusion of MWCNTs effectively enhanced the wear performance of the composites at elevated temperatures. Overall, this study provides valuable insights into the friction and wear characteristics of PALF-reinforced NR composites with the addition of MWCNTs, enhancing their end-use properties for high-temperature applications. Highlights: Improved wear and frictional properties of NR/30PALF composites with MWCNTs. MWCNTs enhance heat dissipation, reducing softening at elevated temperatures. Frictional force and COF decreased with increasing temperature and load. NR/30PALF/MWCNT composites showed smoother surfaces and lower wear rates. Thermal stability and wear resistance of the composites were enhanced.

    Replacing synthetic fibres with natural fibres as reinforcement fillers in natural rubber (NR) tends to yield eco-friendly bio-composites. This study investigated the tensile and hardness properties, and the thermal behaviour of pineapple leaf fibre (PALF)-reinforced NR composites with and without the addition of multi-walled carbon nanotubes (MWCNT). The fibre content was varied at 0, 10, 20, and 30 parts per hundred rubber (phr) and the MWCNT content was fixed at 10 phr. The surface morphology of the tensile-fractured specimens was examined using scanning electron microscopy (SEM) to identify the rubber-matrix adhesion and tear mechanisms of the fibres in the NR matrix. The results revealed that including the PALF and MWCNT allowed the NR composites to exhibit excellent stretching stress at low elongations. Additionally, the composites displayed enhanced stiffness, further increasing the hardness of the composite, ranging from 46.8 to 62.8 Shore A. However, PALF reduces the thermal stability of the composite, where the initial degradation temperature increases. From the thermogravimetric analysis, the residues remaining in the NR composites ranged from 6 to 13% at various fibre loadings. Therefore, this study provides valuable insights into the tensile and hardness properties and the thermal behaviour of PALF-reinforced NR composites to improve end-use properties.
