Puncture resistance of nanofilled coated high strength woven fabric

This paper reports on the effects of nanofiller on the puncture resistance of high strength coated woven fabric. High strength Kevlar woven fabric was coated with natural rubber latex (NRL) and carbon nanotube (CNT) (1 phr, 3 phr, 5 phr) filled NRL. The coated fabrics were tested for puncture resistance test and the results were compared with neat fabrics. Three puncture probes with different geometry were used to test the fabrics which were conical probe, ogival probe and hemispherical probe. The NRL coated fabric gave higher puncture resistance in comparison with the neat fabric. The result also showed that the CNT filled influenced the properties of the coated fabric by increasing the resistance to puncture for all probe shapes. The 1 phr CNT turned out to give the highest puncture resistance. Among the puncture probe geometry, the hemispherical probe gave the highest puncture resistance in comparison with the ogival and conical probe.
