The invention provides a novel far infrared heater and a preparation method thereof. The novel far infrared heater comprises surface films, a heating sheet, an adhesive layer, a core material and a curing sheet, the heating sheet, the core material and the curing sheet are sequentially attached through the adhesive layer, and the surface films are respectively arranged on the upper surface of the heating sheet and the lower surface of the curing sheet; and integral compounding and molding are achieved. The novel far infrared heater is endowed with a heating function on the basis of light weight of the aramid fiber honeycomb composite material plate/part, so that the integration of the structure and the function is realized, and the heating problem in the fields of rail transit, aerospace and the like is solved. 本公开提供了一种新型远红外发热器及其制备方法，所述新型远红外发热器包括表面膜、发热片、粘合剂层、芯材和固化片，其中发热片、芯材与固化片依次通过粘合剂层贴合设置，并分别在发热片的上表面和固化片的下表面设置表面膜；一体复合成型。本公开的新型远红外发热器在芳纶蜂窝复合材料板/制件的轻量化的基础上，赋予了其发热功能，实现结构功能一体化，解决了轨道交通和航空航天等领域取暖的问题。
