My helmet meets all of the safety standards a helmet should have. It will keep the user safe in situations of high acceleration. The helmet has a face shield which will protect the user from wind speeds as a result of high acceleration. This helmet will also protect the head from friction in the case of an accident because of its thick double layer of composite carbon fiber and Kevlar. The front of the helmet sticks out 4 inches. This acts as a crumple zone. If an accident is to occur this part of the helmet will absorb the energy of the energy of the collision instead of causing damage to the users face. The helmets slick smooth design helps prevent drag . The purpose of this is to prevent as much fluid resistance on the helmet. The helmet is not designed to bend in any place but the front shield. Inertia keeps the helmet moving in a constant direction and prevent outside factors like wind speed from affecting the overall function.\ The helmet is made of strong material which prevents force on the back of the head in the case of the dirt bike landing on the rider. The inner lining and the outside shell are an example of kinetic friction because they both rub on each other to a point as it is used in motion. Materials - The inner lining is made up of expanded polystyrene which protects the head from trauma and provides the user with a comfortable fit. The outside shell of the helmet is made up of a mixture of composite carbon fiber, Kevlar, and fiberglass. These materials provide a strong durable fit which protects the head from impact.
Design Explanation
The helmet I created is modeled to look and function after a motorcycle helmet. Specifically a dirt bike helmet. This helmet has a cushioned inner lining to protect the head from blunt force trauma. On the outside the helmet has a hard shell made up of composite carbon fiber, Kevlar, and fiberglass. It has an opening at the front where goggles can be applied to prevent dust and other debris from entering the users face.
