Carbon/carbon composite material breathable ring as well as preparation method and application thereof
The invention relates to the technical field of breathable rings, and provides a carbon/carbon composite breathable ring as well as a preparation method and application thereof. The preparation method comprises the following steps: sequentially carrying out dipping curing, carbonization and graphitization heat treatment on a carbon fiber breathable ring preform to obtain a graphitized breathable ring blank; the graphitized breathable ring blank is subjected to purification treatment and heat treatment after being subjected to finish machining, and the carbon/carbon composite breathable ring is obtained. According to the preparation method, a dipping carbonization process and a high-temperature purification process are combined, the carbon/carbon composite material breathable ring with high density and high breathability is prepared, the use requirement of a photovoltaic thermal field is better met, meanwhile, the thermal field mechanical property is higher, the service life is longer, the energy consumption is lower, the production cost of an enterprise can be reduced, and the ever-increasing photovoltaic thermal field accessory requirement is met. Moreover, the prepared breathable ring is high in purity, simple in process, convenient to operate, short in preparation period, low in production cost and suitable for large-scale industrial production.
本发明涉及透气环技术领域，提供了一种碳/碳复合材料透气环及其制备方法和应用。本发明将碳纤维透气环预制体依次进行浸渍固化、碳化、石墨化热处理，得到石墨化透气环坯体；将石墨化透气环坯体精加工后进行纯化处理和热处理，得到碳/碳复合材料透气环。本发明结合浸渍碳化工艺和高温纯化工艺，制备得到高密度、高透气性的碳/碳复合材料透气环，更符合光伏热场的使用要求，同时其热场力学性能更高，使用寿命更长，能耗更低，可降低企业生产成本，满足日益增长的光伏热场配件需求。并且，本发明制备的透气环纯度高，且工艺简单、操作方便、制备周期短、生产成本低，适合进行大规模工业化生产。
