The safety helmet is a protective equipment to prevent the impact from hurting the head. Composed of cap shell, cap liner, lower cheek strap and back hoop. When the operator's head is impacted by falling objects, the impact force is decomposed to the entire area of the skull by using the helmet cap shell and cap lining in an instant, and then most of the impact force is absorbed by using the elastic deformation, plastic deformation and allowable structural damage of the buffer structure of each part of the helmet, so that the final impact force applied to the head of the operator is reduced to less than 4900N, thus protecting the head of the operator. The cap shell material of the safety helmet plays an important role in the overall resistance performance of the safety helmet.
