NOVELTY - Preparing high-strength aerogel composite material involves using long fibers as sutures to sew fiber fabrics and fiber mats to obtain fiber preforms, compositing fiber preform with aerogel precursor, and obtaining aerogel composite material through sol-gel and drying. The precursor solution is compounded and strengthened on fabric layer on surface of aerogel composite material, and cured and formed to obtain high-strength aerogel composite material. USE - Method for preparing high-strength aerogel composite material. ADVANTAGE - The method enables to provide high strength aerogel composite material with excellent comprehensive performance, especially excellent mechanical property, and the technique is simple, has high strength, low cost and short production period, and is suitable for mass production.
