Abstract

New dampers are provided by reinforced fibers in a full density network. Their mechanism is on their network structures that disperse the projectile energy in a wide area. Shear thickening fluid (STF) is made from the combination of nanoparticles with a specified weight fraction in polyethylene glycol to increase damping in network structures. To immerse fibers, STF is diluted in ethanol, and the fibers are placed therein for a specified period to impregnate all fibers in the fluid. To eliminate the sample ethanol, specimens are heated at 60°C to 80°C. Combining ethanol with fluid and eliminating ethanol reduce the sensitivity of the composite to the impact. Energy dissipation is highest in the 3:1 portion (ethanol and STF) because of the insignificant influence on the nanoparticle interface and polymer. However, decreasing the amount of ethanol makes the dispersion of STF unsuitable.
