Micro Air Vehicles are the logical successors to modern aircraft and advancements in automated technology. In recent years, the use of Micro Air Vehicles (MAV) and Unmanned Aerial Vehicles (UAV) are playing important roles in different applications. It is used in many aspects of military and civil broadly, such as aerial photogrammetry, warzone, reconnaissance, attack missions, surveillance of pipelines, and interplanetary exploration and so on. The current trend in aircraft structural design is to use composite materials as primary structural elements. The main objective of this work is to analysis of Mechanical behavior of 3D printed composite materials Carbon Fiber PLA and Carbon Fiber Reinforced PET-G parts by varying various 3D- printing parameters like Printing Speed (mm/sec), Infill Density (%), and Layer Height (microns). Various tests such as Tensile Test, Compression test and Flexural test and are performed to determine failure characteristics of Carbon Fiber PLA and Carbon Fiber Reinforced PET-G materials. Optimization techniques like Taguchi and Taguchi Grey Relational Analysis are also applied to know the printing parameters influence on the mechanical properties of the printed part in order to obtain how parts can be manufactured (printed) to achieve improved mechanical properties. The ANOVA also carried out to know the percentage contribution of printing parameters.
