本发明涉及碳化毡的一种新的制备方法，具体涉及一种组合功率法PAN基预氧化纤维针刺毡制备碳化毡方法，包括如下步骤：S1、以第一功率P1石英板远红外定向辐射器对PAN基预氧化纤维针刺毡进行第一次高温碳化处理；S2、以第二功率P2石英板远红外定向辐射器对PAN基预氧化纤维针刺毡进行第二次高温碳化处理；S3、以第三功率P3石英板远红外定向辐射器对PAN基预氧化纤维针刺毡进行第三次高温碳化处理；其中，P2大于P1、P3大于P2。本发明是利用远红外组合功率法将PAN基预氧化纤维针刺毡制备成碳化毡，打破传统在N2保护下高温碳化炉内制备碳化毡的做法，制备的碳化毡质量稳定、生产成本低、工艺简单、大幅度降低能耗。 The invention relates to a novel preparation method of a carbonized felt, in particular to a method for preparing the carbonized felt from a PAN-based pre-oxidized fiber needled felt by a combined power method. The method comprises the following steps of S1, performing first high-temperature carbonization treatment on the PAN-based pre-oxidized fiber needled felt by using a quartz plate far-infrared directional radiator with first power P1; S2, performing second-time high-temperature carbonization treatment on the PAN-based pre-oxidized fiber needled felt by using a quartz plate far-infrared directional radiator with second power P2; and S3, performing third-time high-temperature carbonization treatment on the PAN
