ARAMID FABRIC AND AIRBAG FOR VEHICLE INCLUDING SAME

摘要

This invention relates to an aramid fabric and an airbag for a vehicle including the same, and more specifically, to an aramid fabric and an airbag for a vehicle including the same, wherein the aramid fabric can endure high levels of impact force and can exhibit superior air sealing performance, dimensional stability and packing property, and can thus be adapted for use in an external airbag for a vehicle. The aramid fabric includes an aramid fabric layer including an aramid yarn having a fineness of 300 to 1000 denier; and a rubber coating layer formed on the aramid fabric layer, wherein the strength-elongation index (TIwa) in a warp direction of the fabric as defined by a predetermined equation is 2.8 to 4.8, and the coating amount of the rubber coating layer is 20 to 100 g/m2.

1. An aramid fabric, including:
an aramid fabric layer comprising an aramid yarn having a fineness of 300 to 1000 denier; and a rubber coating layer formed on the aramid fabric layer, wherein a strength-elongation index (Twa) in a warp direction of the fabric is 2.8 to 4.8, as defined by Equation 1 below, and a coating amount of the rubber coating layer is 20 to 100 g/m2:
TIwa=Twa/(Swa×D)  Equation 1 wherein Twa is tensile strength (N/5 cm) in a warp direction of the aramid fabric as measured by International Organization for Standardization ISO 13934-1 method, Swa is tensile elongation (%) in a warp direction of the aramid fabric as measured by International Organization for Standardization ISO 13934-1 method, and D is fineness (denier) of the aramid yarn.
