What material is categorized as semi rigid?

Semi-rigid materials exhibit a balance between flexibility and strength, allowing for some deformation under stress while still maintaining structural integrity. Plastic is a prime example of a semi-rigid material because it can absorb impact and flex under stress without breaking, making it commonly used in automotive applications such as bumpers and interior components.

Aluminum, while lightweight and strong, is more rigid than plastic and is typically categorized as a rigid material. Steel is also considered rigid and is often used in areas requiring high strength and durability, such as the frame and body of a vehicle. Fiberglass, although somewhat flexible, is generally more brittle than plastic and does not fall into the semi-rigid category as effectively.

Understanding the properties of materials is essential in auto collision repair, as selecting the right material for specific applications can significantly affect the performance and safety of repaired vehicles.
