Outline
In order to investigate the arc resistance of coating modified polyimide fabric, a waterborne polyurethane was used as matrix to prepare a barrier thermal insulating coating with SiO2 aerogel and a reflective thermal insulating coating with TiO2 filler, and then two coatings were applied on the polyimide fabric, respectively. The effect of filler addition amount and the matrix on the thermal protection performance and rupture performance of polyimide fabric under the effect of fault arc was studied. The results show that the thermal protection performance of the modified polyimide fabric increases with the increase of filler addition, the thermal protection performance of polyimide modified by thermal insulating coating with 6% of SiO2 and 6% of TiO2 increases by 34.79% and 21.78%, respectively. Waterborne polyurethane matrix has no effect on the thermal protection performance of polyimide fabrics, but it can make their rupture performances increase by 20%.
