Thermal resistant coatings of textile materials are required so that they can fulfill the high
security demands in the case of resistance to fire. These coatings also improve the
properties of textiles as composite materials. In this research work, a polysilazane based
coating was applied on carbon filament (CF) and glass filament (GF) rovings by a padding
method. Tensile testing under thermal stress was carried out to assess the
thermomechanical properties of both coated and uncoated rovings. Scanning electron
microscopy, energy dispersive X-ray analysis, contact angle measurements, and surface
energy calculations were performed to evaluate the surface properties of coated and
uncoated rovings. The amount of coating mass on rovings was also determined using
different recipes. Thermo-gravimetric analysis and weight loss after thermal treatment of
coated and uncoated CF rovings were carried out to observe the oxidation behavior, as
well as the thermal stability. The obtained testing results were assessed to ascertain the
coating performances on GF and CF rovings.
