The invention belongs to the technical field of carbon fiber ceramic composite materials, and particularly relates to a novel carbon ceramic fiber thermal insulation material and a preparation method thereof. Comprising at least one carbon fiber non-woven felt body layer, at least one ceramic fiber felt body layer; the ceramic fiber felt body layer is arranged outside the carbon fiber non-woven felt body layer, and phenolic resin is sprayed between the ceramic fiber felt body layer and the carbon fiber non-woven felt body layer; the ceramic fiber felt body layer is composed of one or more of aluminum oxide and/or silicon dioxide fibers. The carbon fiber ceramic composite material provided by the invention has better electromagnetic wave scattering property, better oxidation resistance, better heat insulation effect and lower heat conductivity, and effectively solves the technical problems of high manufacturing cost, poor heat insulation effect, high possibility of delaminating and cracking and the like of the existing heat insulation and heat insulation materials.
本发明属于碳纤维陶瓷复合材料技术领域，特别是涉及一种新型碳陶纤维隔热材料及其制备方法。包括，至少一层碳纤维非织造毡体层；至少一层陶纤维毡体层；所述陶纤维毡体层设置在碳纤维非织造毡体层外，二者之间还喷涂有酚醛树脂；所述陶纤维毡体层由三氧化二铝和/或二氧化硅纤维中的一种或几种组成。本发明提供的碳纤维陶瓷复合材料，具有更好的电磁波散射性，以及具有更好的抗氧化性，隔热效果更好，热传导率也更低，有效解决了现有的隔，热材料，制造成本高，隔热效果差，易发成脱层、开裂等技术问题。
