Abstract

Utilizing cocoon waste as reinforcement in composites offers a cost-effective alternative for soft body armour production. Cocoon waste, including damaged or uncoiled cocoons and those with pupae, is recognized as an eco-friendly choice. This study aims to develop and assess the incorporation of varying amounts of cocoon waste as reinforcement in epoxy resin matrix composites through the cold pressing process. The cocoon waste content in the composite specimens ranged from 0 – 40 wt%. Tensile testing and ballistic impact testing were conducted to evaluate specimen performance. The cocoon waste composite plate exhibited a maximum tensile strength of 62.21 MPa at 30 wt%, slightly surpassing that of woven hemp. These findings indicate the advantageous reinforcement attributes of cocoon waste. However, a limitation was identified: bullets fully penetrated the composite plate. To address this, ultra-high-molecular-weight polyethylene was incorporated in cocoon waste composite, resulting in enhanced tensile strength (107.36 MPa) and complete bullet penetration prevention. These outcomes position the study as a promising avenue for developing body armour plates meeting the stringent Level II certification standards set by the National Institute of Justice.
用冷压工艺从蚕茧废料中轻松生产盔甲
利用蚕茧废料作为复合材料的增强材料,为软体护甲的生产提供了一种具有成本效益的替代方法。蚕茧废料,包括破损或未卷曲的蚕茧和带蛹的蚕茧,是公认的环保选择。本研究旨在开发和评估通过冷压工艺在环氧树脂基复合材料中加入不同数量的蚕茧废料作为增强材料的情况。复合材料试样中的蚕茧废料含量范围为 0 - 40 wt%。拉伸试验和弹道冲击试验对试样性能进行了评估。蚕茧废料复合材料板在 30 wt% 时的最大拉伸强度为 62.21 MPa,略高于编织麻。这些结果表明了蚕茧废料的优势增强属性。但也发现了一个局限性:子弹完全穿透了复合板。为了解决这个问题,在蚕茧废料复合材料中加入了超高分子量聚乙烯,从而提高了拉伸强度(107.36 兆帕),并完全防止了子弹的穿透。这些成果使这项研究成为开发符合美国国家司法研究所制定的严格二级认证标准的防弹衣板的可行途径。
