其他摘要：Fire helmet with optimized structure design can protect firefighters from hurt even in the case of the helmet being stroked by heavy objects or punctured by blunt; fire helmet can prevent fire-fighters being burned by selecting material of main components; fire helmet can protect firefighters from hunt by heavy strike and blunt puncture through selecting main components processing and forming. This article will illustrate that the security performance of the fire helmet can only be fully ensured when fire helmet structure optimization and correct selection of components material and molding applications being considered comprehensively. In other word, security performance of the fire helmet can not be guaranteed if only one or few factors be considered./span>
