Abstract: Composite materials containing epoxy/glass fiber have good strength and are of low weight. They are ideal for producing parts for automobile and railway locomotives. These composites lose their strength with age and exposure to UV rays, and exposure against solar radiation increases the rate of degradation of such materials. Fiber metal laminates (FML) are a new type of composites which can replace many other composites, as they use a metal cover over the ceramic core. They are widely used for a variety of structures in automobiles, locomotives, and aeroplanes owing to their good formability. In this experimental study, an aluminium alloy AA5052 H32 and glass fiber-reinforced polymer composite was prepared using the hand lay-up method. The FML composite was tested for tensile, shear, flexural, and Charpy impact strengths, hardness, and was subject to the Erichsen cupping test. The interface structure of the tensile test specimen characterized had fiber orientation of different sequences (0°, 45°, 90°). Further examination showed that the FML possessed fairly good mechanical properties indicating their ability to absorb light loads applied through tension, bending, and impact.
