Due to differences in application fields and intended use, UAVs (Unmanned Aerial Vehicles) differ significantly from conventional manned aircraft in terms of manufacturing materials and airframe structures. When designing manned aircraft, the primary consideration is human safety, which imposes stri

HP-RTM, short for High Pressure Resin Transfer Molding, is a manufacturing process that involves injecting resin under high pressure into a vacuum-sealed mold pre-laid with fiber-reinforced materials and pre-positioned inserts. The process includes resin flow filling, impregnation, curing, and demol

Since the beginning of the 21st century, the maturation of lithium-ion battery technology has fueled the rapid development of electric vehicles (EVs). In recent years, EV penetration has accelerated, creating a disruptive trend against traditional internal combustion engine vehicles. However, challe
