Fabrication And Analysis Of Industrial Safety Helmet Structured Of Composite Materials

Abstract

All helmets attempt to protect the user’s head by absorbing mechanical energy and protecting against penetration. Their structure and protective capacity are altered in high-energy impacts. Beside their energy-absorption capability, their volume and weight are also important issues, since higher volume and weight increase the injury risk for the user’s head and neck. Every year many workers are killed or seriously injured in the construction industry as a result of head injuries.

Composite materials as heterogeneous materials consisting of two or more solid phases, which are in intimate contact with each other on a microscopic scale, they can be also considered as homogeneous materials on a microscopic scale in the sense that any portion of it will have the same physical property.
