<p>Most stab-proof vests in use are made from metal plates, whose weight, bulk, and rigidity make them unsuitable for use over extended periods of time. Light, thin, and flexible clothing that protects against knives and other sharp objects is needed. However, achieving high levels of puncture resistance and comfort remains a challenge. While plain textiles can resist slashing, they cannot withstand stabbing. In this study, we investigated the stab resistance of aramid fabrics impregnated with micro-glass particles and nano-silica particles and evaluated the influence of particle size and mass concentration by measuring the load, displacement, and energy when the samples were struck by a blade. Particle-impregnated fabrics showed good puncture resistance. The smaller the diameter of the particles, the greater the material's resistance to penetration. Movement of yarn strands is inhibited by impregnation with particles. Furthermore, the friction force acting on intersecting sections of plain fabric exhibits the largest influence on stab resistance.</p>
