Method for preparing boron nitride modified carbon/carbon composite material product and product
The invention belongs to the field of preparation of carbon/carbon composite material products, and relates to a preparation method of a boron nitride modified carbon/carbon composite material product and the product. In order to solve the technical problem that a carbon/carbon composite material product is easy to oxidize, the invention provides a method for preparing a boron nitride modified carbon/carbon composite material product, which comprises the following steps: preparing a carbon fiber preform by adopting a needling method, carrying out boron nitride modification on the carbon fiber preform before densification treatment on the carbon fiber preform, and after modification, preparing the boron nitride modified carbon/carbon composite material product. The carbon fiber in the carbon fiber preform is wrapped by the boron nitride coating, so that the carbon fiber preform has better oxidation resistance.
本发明属于炭/炭复合材料制品制备领域，涉及一种氮化硼改性炭/炭复合材料制品的制备方法及制品。为了解决炭/炭复合材料制品易氧化的技术问题，本发明提供一种制备氮化硼改性炭/炭复合材料制品的方法，该方法采用针刺法制作碳纤维预制体，在对碳纤维预制体进行致密化处理之前对碳纤维预制体进行氮化硼改性，改性后，碳纤维预制体中的碳纤维被氮化硼涂层包裹，具有更好的抗氧化性。
