Today, the use of polymer and plastic materials in the automotive industry has expanded so much that it can be said that more than 50% of the parts of the automotive industry are made of polymer materials, and it has created a huge transformation in this industry. The advantages of using these materials instead of other parts have brought things such as lower costs, more integrated connections, easier assembly, etc. to this industry.
The use of plastic materials in many interior parts such as consoles, mirrors, seats, etc., in order to increase the usable space, etc., is seen more than in the past. Also, using them in external parts such as bumper, body, lights, etc., in addition to beauty, has created better efficiency. In addition to these, research on the construction of various parts of the car using these materials is carried out with the aim of stylization, higher safety, cost reduction, more beauty, etc., and is the subject of research by thousands of researchers as current research discussions.
