Optimizing the Anti-stab Performance of Fiber Composites by Using Ceramic Particle Reinforcements

Abstract

Abstract Fiber reinforced composite is widely used in current stab-proof equipment, the high performance and light weight have always been pursued for a long time. The present study optimizes the anti-stab performance of fiber composites by using silica and silicon carbide ceramic particle reinforcements. The anti-stab performance of different composite processes and composite structures were characterized. Silica particle reinforcements were added to the fiber fabric in the form of a shear thickening fluid (STF). Quasi-static puncture tests results revealed that the puncture force of the fiber composite prepared by STF dilution process was significantly higher than that of the sample prepared without dilution. Under the same areal density, the puncture force of the sample with a dilution ratio of 1:2 had been improved by 79.9% higher than that of pure fiber fabrics. Silicon carbide particle reinforcements were added to the fiber fabric in the form of particles/epoxy resin coating. After coated with SiC particles, the aramid fiber fabric not only greatly improves the puncture force, but also significantly increases the wear of the tool. The dynamic puncture test results further showed that the SiC coated / STF aramid plain weave fabrics exhibited excellent stab-resistant performance.
