Stab resistance of smart polymer coated textiles reinforced with particle additives
Selim Gürgen,Tolunay Yıldız +1 more
TL;DR: In this paper, different amounts of carbide particles were included in a shear stiffening polymer and the influences of additives were investigated through rheological measurements, and it can be stated that carbide reinforced particles result in much stiffer properties in the polymers however, the composites still keep their viscous behavior at low shear rates.
