What is the role of impact-resistant materials in helmet construction?

Impact-resistant materials are crucial in helmet construction because they are specifically designed to absorb and distribute the force of impacts. When a helmet experiences a collision, the materials used must be able to withstand significant pressure and sudden forces to protect the wearer’s head from injury. This strength is essential for preventing cracks or fractures in the helmet, which could compromise safety. By using these materials, manufacturers ensure that helmets can effectively protect against falls, blows, and other impacts, thus enhancing the safety and reliability of the helmet in critical situations. The other options, while they may have some merit, do not directly relate to the primary function of helmets in providing protection during impacts.
