The Influence of the Kaolin Content on the Thermal Protection Property of Double-Layer Coating of Flexible Composites

The comparison and analysis for the preparation of related performance indicators of the thermal protection such as the ablation resistance performance, thermal stability at high temperature and reflection ability of the heat ray of kaolin double-layer coated flexible composites were carried on. Because of the 2 d stratified structure of kaolin, and at the same time it processes the higher refractoriness, excellent resistance to the elevated temperature, the certain heat insulation and the reflection performance of the heat ray, the adequate padding of kaolin can improve the prepared thermal protection ability of double-layer coating of flexible composites.
