Fiber-reinforced composites are increasingly used as an outer shell of sporting helmets as an alternative to conventional thermoplastic shells like Acrylonitrile butadiene styrene (ABS), Polyurethane (PU), and polycarbonate (PC) for improved protection. The current research presents a detailed study to manufacture novel woven carbon/Elium® (WEL) thermoplastic composite helmets and investigate the details based on the impact tests following the industrial safety certification criteria (CPSC 1203 helmet certification) tests on the flat, curb-stone, and the hemispherical anvils. The effect of thermoplastic Elium® resin toughened thermoplastic Elium® IM, and Epoxy resin is investigated to understand the benefits offered by the thermoplastic variants in terms of safety, energy absorption, and the impact failure mechanisms. Post-failed Carbon/Elium® thermoplastic composite shells have shown more ductile and less catastrophic damage as opposed to the Carbon/Epoxy composite shell damage. The impact damage mechanisms as observed from the in-situ high-speed camera images have shown more deformation-dominated failure mechanisms for the composite shells manufactured with Elium® and toughened Elium® resin. Carbon/Epoxy composite shells have shown lower energy absorption and the nature of the failure was more catastrophic and more cracks were noticed on the inner side of the foam which is directly attached to the human head. In case of an impact on a flat anvil, the PC shell configuration has shown a critical injury rate of 28.7% and a fatality rate of 6%. With the manufactured Carbon/Elium® composite helmets, the chances of critical and fatal injury rates are reduced to 16.7% and 3% respectively.

纤维增强复合材料越来越多地用作运动头盔的外壳，以替代传统的热塑性塑料外壳，如丙烯腈丁二烯苯乙烯 (ABS)、聚氨酯 (PU) 和聚碳酸酯 (PC)，以提供更好的保护。目前的研究提出了一项详细研究，以制造新型编织碳/Elium® (WEL) 热塑性复合材料头盔，并根据工业安全认证标准（CPSC 1203 头盔认证）对平坦路缘石进行的冲击测试研究细节，以及半球形的砧座。对热塑性Elium®树脂增韧的热塑性Elium®IM和环氧树脂的效果进行了研究，以了解热塑性变体在安全性，能量吸收和冲击破坏机理方面的优势。与碳/环氧树脂复合材料外壳损坏相比，失效后的 Carbon/Elium® 热塑性复合材料外壳显示出更高的延展性和更少的灾难性损坏。从原位高速摄像机图像中观察到的冲击损坏机制表明，对于使用 Elium® 和增韧 Elium® 树脂制造的复合材料外壳，更多以变形为主的失效机制。碳/环氧树脂复合材料外壳显示出较低的能量吸收，故障的性质更具灾难性，并且在直接连接到人头部的泡沫内侧发现了更多裂缝。在撞击平砧的情况下，PC 外壳配置显示出 28.7% 的致命伤害率和 6% 的致死率。使用制造的 Carbon/Elium® 复合头盔，重伤和致命伤害的几率降低到 16。
