The increasing demand for sustainable and lightweight composite materials has led to significant research in natural fiber-reinforced composites (NFRCs). This study explores the mechanical properties, durability, and performance of hybrid composites that combine natural fibers (such as jute, flax, or hemp) with glass fiber-reinforced polymers (GFRP). The goal is to evaluate how natural fibers enhance material sustainability while maintaining the structural integrity of traditional GFRP composites...........

Engine cylinder fins play a crucial role in dissipating heat from internal combustion engines, ensuring efficient thermal management and preventing overheating. This study focuses on the examination and evaluation of the heat transfer properties of engine cylinder fins under various operating conditions and geometric configurations. The research involves both experimental and numerical analysis to assess the thermal performance of different fin designs. Computational Fluid Dynamics (CFD) simulations are conducted to analyze temperature distribution, heat dissipation rates, and airflow behavior over the fins..........

The oval wing design has gained attention in modern aircraft engineering due to its aerodynamic efficiency, reduced drag, and structural advantages. Unlike conventional rectangular or tapered wings, the oval wing configuration offers a unique balance of lift distribution, maneuverability, and fuel efficiency, making it a promising alternative for commercial, military, and unmanned aerial vehicles (UAVs)........

With the help of CAD, rapid prototyping of physical objects can be achieved. In this method, objects are produced by stacking material in layers. This technology is also known as additive manufacture. There are five of the most common rapid prototyping such as visualization, appropriate forms, product testing, tools, and use of spare parts. 3D printer is an example of a machine that uses rapid prototyping. In this paper, we have discussed about designing and creating a 3D printer using the FDM method, FDM utilizes material extruded from a nozzle which is then driven by a motor............
