Abstract
Abstract: A helmet is a type of head protection that is worn on the head. By decreasing the impact of a force or collision to the head, a helmet seeks to lessen the risk of significant head and brain injuries. The shell, EPS liner, Comfort liner, Cheek pads, Visor, and Retention or closing mechanism are the different sections of a helmet. The outer shell of a motorcycle helmet can be made lighter and more comfortable by using materials that reduce weight and absorb energy. Metal foams are a type of cellular material that has a number of fascinating qualities, including high stiffness and low specific weight, as well as effective energy absorption. These distinct features make them suitable for a wide range of applications, from car bumpers to aircraft crash recorders. Keywords: Helmet, Material Selection, CFRP, Bluetooth
