“…Ballistic performance -Ballistic protection is a primary consideration in the fielding of a new helmet. For example, for the World War II steel M1 helmet, the ballistic performance was measured by the helmet's ability to defeat a pistol ball traveling at a certain velocity [16]. The ballistic performance of a composite helmet depends on the material used, helmet thickness, and fabrication method.…”

“…The M1 helmet was the longest serving helmet. The M1 helmet could defeat a pistol shot fired at a certain velocity, as required by the ballistic criterion imposed then [16]. However, the M1 helmet was manufactured in only one size (e.g., [79]).…”

“…These modern-era helmets have saved many lives and received great praise. Since their successful implementation, the trend for helmet development has been mainly towards weight reduction, and the concept of ''a soldier as effective as a tank'' (e.g., [16]) has become appealing to the Army. It has been envisioned that an advanced helmet should have a remote sight, a night vision device, a GPS, and a laser range finder to make an individual soldier a more effective fighter.…”

a b s t r a c tProtecting a soldier's head from injury is critical to function and survivability. Traditionally, combat helmets have been utilized to provide protection against shrapnel and ballistic threats, which have reduced head injuries and fatalities. However, home-made bombs or improvised explosive devices (IEDs) have been increasingly used in theatre of operations since the Iraq and Afghanistan conflicts. Traumatic brain injury (TBI), particularly blast-induced TBI, which is typically not accompanied by external body injuries, is becoming prevalent among injured soldiers. The responses of personal protective equipment, especially combat helmets, to blast events are relatively unknown. There is an urgent need to develop head protection systems with blast protection/mitigation capabilities in addition to ballistic protection. Modern military operations, ammunitions, and technology driven war tactics require a lightweight headgear that integrates protection mechanisms (against ballistics, blasts, heat, and noise), sensors, night vision devices, and laser range finders into a single system. The current article provides a comparative study on the design, materials, and ballistic and blast performance of the combat helmets used by the US Army based on a comprehensive and critical review of existing studies. Mechanisms of ballistic energy absorption, effects of helmet curvatures on ballistic performance, and performance measures of helmets are discussed. Properties of current helmet materials (including Kevlar Ò K29, K129 fibers and thermoset resins) and future candidate materials for helmets (such as nano-composites and thermoplastic polymers) are elaborated. Also, available experimental and computational studies on blast-induced TBI are examined, and constitutive models developed for brain tissues are reviewed. Finally, the effectiveness of current combat helmets against TBI is analyzed along with possible avenues for future research.

“…For wadded TTAI fabrics, both binding warp spacing and wadding warp spacing need to be considered. The binding warp spacing and the weft spacing are still calculated according to Equation (1) and Equation ( 2), and the wadding warp spacing (L 1 ') follows equation (3). L 0 1 ¼…”

Modern ballistic helmets made from textile composites offer enhanced protection with lightweight, but the discontinuity of the reinforcing materials is a potential problem affecting the helmet performance. This work uses 3D angle-interlock fabrics to provide reinforcement continuity, and evaluates 3D through-the-thickness angle-interlock (TTAI) fabrics to study the influence of fabric structural parameters on fabric mouldabilty and ballistic performance for ballistic helmet application. The mouldability was measured through experiments and modelled numerically, and the ballistic impact test was carried out to identify the optimal fabric structures for constructing ballistic helmet shells. The results show that increase in weft density of the TTAI fabrics causes decrease in the mouldability of the TTAI fabrics, and that the addition of wadding yarns into the TTAI fabrics has little influence on fabric mouldability compared to the conventional TTAI fabrics with the same weft density. However, the involvement of wadded TTAI fabrics demonstrates a 34% increase in ballistic energy absorption and 3% higher estimated ballistic limit over the conventional counterpart. Taking both mouldability and ballistic protection into account, the wadded TTAI fabric structure is an effective continuous reinforcement for ballistic helmet shells, offering required mouldability and improved ballistic performance.
