The College of Materials Engineering, University of Babylon discussed a master’s thesis on recycling of spent car battery casings and their use in manufacturing highly efficient, impact-resistant car bumpers by the postgraduate student, Ms. Zahraa Falah Mahdi.

The thesis aimed at recycling car battery casings for use in industrial applications, blending polypropylene derived from recycled battery casings with raw materials and glass fibers in precise, standardized ratios then reprocessed using modern extrusion techniques, and the resulting innovative material underwent a series of mechanical and thermal tests.

The thesis reviewed that adding 25% glass fiber achieved the optimal balance between rigidity and durability, while also reducing weight and significantly improving the material's flexibility and impact resistance, furthermore, computer simulations of collision dynamics based on passenger safety standards demonstrated that the new material possesses a higher safety factor than conventional materials. 

This makes it a sustainable, effective local alternative both mechanically and economically for the manufacture of vehicle bodies and bumpers.
