Abstract

Inspired by the overlapping structure of snake scales, a reinforced scale-like knitted fabric (R-SLKF) was created in this work. To achieve this, short carbon fibers in an epoxy resin (ER) matrix were incorporated into the scales of an SLKF. The resulting textile is a highly stable protective composite that is flexible, warm, and thermally insulated. In addition, superior stab-resistance is ensured through rigid protective blocks in the R-SLKF, making up a hard overlapping scale region, besides satisfactory flexibility via soft twisted ultra-high-molecular-weight polyethylene yarn-based textiles. The R-SLKF achieves high stab resistance (peak load of approximately 600 N for a single scale thickness of 2 mm), good flexibility (~ 290 mN cm), and breathability (100 MPa, 423 mm/s), coupled with good warmth retention and thermal insulation properties (0.28 ℃/s), which are superior to previously reported protective composite textiles. From the results, the combination of desirable individual protection, excellent wearability and comfort enables human beings to survive in extremely dangerous environments. Finite element simulations provided valuable insights into the factors influencing the stab resistance of R-SLKF and elucidated the underlying anti-puncture mechanism in accordance with the experimental findings. This study presents a novel strategy for the facile industrial fabrication of flexible and lightweight protective composite textiles, which is expected to enhance the structure and material design for future innovations and provide advantages for personal protective equipment in various industrial fields.

大规模制造受蛇皮启发的防护复合纺织品

受蛇鳞片重叠结构的启发，这项工作创造了一种增强型鳞片状针织物（R-SLKF）。为此，在 SLKF 的鳞片中加入了环氧树脂（ER）基质中的短碳纤维。这种织物是一种高度稳定的保护性复合材料，具有柔韧性、保暖性和隔热性。此外，R-SLKF 中的刚性保护块构成了一个坚硬的重叠鳞片区域，确保了卓越的抗刺穿性，而基于超高分子量聚乙烯纱线的软捻纺织品则具有令人满意的柔韧性。R-SLKF 具有高抗刺性（单个鳞片厚度为 2 毫米时的峰值载荷约为 600 N）、良好的柔韧性（约 290 mN cm）和透气性（100 MPa，423 mm/s），同时还具有良好的保暖性和隔热性（0.28 ℃/s），优于之前报道的防护复合纺织品。从结果来看，理想的个体防护、出色的可穿戴性和舒适性的完美结合使人类能够在极其危险的环境中生存。有限元模拟对影响 R-SLKF 抗刺穿性能的因素提供了有价值的见解，并阐明了与实验结果一致的抗刺穿机理。这项研究为柔性轻质防护复合纺织品的简便工业制造提供了一种新策略，有望为未来的创新提升结构和材料设计，并为各工业领域的个人防护装备提供优势。
