Abstract In this study, a series of double-layer coated flexible composites with different insulation fillers, like aerogel, hollow glass microspheres and 100 mesh, 200 mesh and 400 mesh’s hollow ceramic microspheres were prepared, and their high temperature insulation performance, high temperature thermal stability and radiant heat protection performance were tested. The results indicated that the chemical composition and internal structures of thermal insulation functional filler had a great influence on the thermal protective performance and thermal stability under high tempe-rature. In the high-temperature thermal insulating performance test, stable temperature of 100 mesh hollow ceramic microballoon double-layer coatedk flexible composite was 360.97 ℃, which was 32.41 ℃ and 57.69 ℃, lower than that of 200 mesh and 400 mesh samples respectively. Among the four samples, TPP time of hollow glass microsphere double-layer coated flexible composite was the longest whose value was 43.13 s. To achieve an ideal effect of thermal protective performance, the thermal insulation functional filler which display greater propensity, more appropriate particle size and higher porosity or hollow ratio should be decided on.
