Abstract
In this study, a 3D model of a PBO/m-aramid and SiC fabric was created in a virtual
space to evaluate the thermal protection performance of each material used in firefighting
suits, and a thermal protection performance simulation study was conducted with
an aim to reduce the material development lead time and development cost. To compare
the thermal protection performance of the PBO/m-aramid fiber woven fabric, which is the
material used for the outer fabric of the existing fire-fighting clothing, and the SiC fiber
woven fabric with different fabric densities (high, medium, and low density), a thermal protection
performance analysis was conducted for each yarn model after creating the geometry
of the fabric model and the finite element model using virtual engineering software.
To analyze the thermal protection performance according to the density difference of the
SiC fiber woven fabrics, three-dimensional (3D) models of the three types of fabrics with
low, medium, and high densities were created. The thermal protection performance analysis
compared the thermal protection performance against the radiation heat source exposure
of the PBO/m-aramid woven fabrics and the SiC woven fabrics according to density as
stated by the KS K ISO 6942 radiant heat protection test method, which is the concrete test
standard. A comparison revealed that the thermal protection performance of the SiC material
was superior to that of the PBO/m-aramid material, and the high-density woven SiC
fabric exhibited the best thermal protection performance.
