Aerospace Composites Malaysia (ACM) Sdn Bhd produces one of the aircraft components, which is an aircraft composite panel. Currently, the painting of the composite aircraft panel is manually conducted by the high skilled human operator. However, there are several issues of manual painting, which are the precision of the thickness specifications, uneven spray, dust-free, microbubble, colour appearance, and contour of the aircraft composite panel. Consequently, these issues contribute to the aircraft aerodynamic performances, productivity, and index time of the aircraft composite panel's production. Thus, the main objectives are to investigate the human painting mimicking robot incorporated with the existing painting environment. The proposed environment becomes smart precision painting systems. In conclusion, the proposed prototype will overcome the quality issue of aircraft composite panel painting faced by Boeing worldwide aircraft industries. Furthermore, the proposed prototype will increase productivity and contribute to the maintaining of the aircraft's aerodynamic performance.

MODENAS CT115 engine is a single overhead camshaft (SOHC) engine, with a rated power of 8.8 horsepower at 9000 rpm. One of the main concerns of engine research is the overheating of engines. Overheating can affects the performance of an engine by leading to a loss of strength and thermal strain. To prevent failure, thermal analysis is used to determine the flow of heat with precision to optimise temperature distribution. The investigation is done using ANSYS Thermal simulation on the CAD model of the engine cylinder head, intake and exhaust valve, and intake and exhaust valve seat insert. The comparison to the existing valve seat insert is made using three different valve seat insert materials: Beryllium-copper C17200, Bronze-copper C61300, and Brass C36000. The research results proved that Brass C36000 provides the best thermal reduction and heat transfer increment compared to the existing valve seat insert material.
