The invention discloses a preparation method of a novel ablation dimensional fiber coating, belongs to the field of special coating coatings, and particularly relates to a preparation and construction method of a fiber composite gradient coating with ablation dimensional performance. The novel ablation dimensional fiber coating prepared by the patent gets rid of the defect of high-temperature decomposition of a resin substrate, takes compound inorganic fibers as main components of the coating, has excellent high-temperature resistance and airflow scouring resistance, has good construction efficiency and lower material cost, and is particularly suitable for the disposable or repeated thermal protection requirements of equipment such as high-speed aircrafts, reentrant aircrafts and missiles with large-area ablation dimensional protection requirements. |
