Carbon fiber heating element and preparation method thereof
The invention discloses a carbon fiber heating element and a preparation method, and the preparation method comprises the steps: mixing phenolic resin, fiber powder and short carbon fibers according to a preset mass ratio to obtain a mixed dry material; injecting the mixed dry material into a mold for mold pressing to obtain a carbon fiber blank; and carrying out densification treatment on the carbon fiber blank body to obtain the carbon fiber heating body. The mixed dry material comprising the phenolic resin, the fiber powder and the short carbon fibers is subjected to compression molding and then densification treatment to obtain the carbon fiber heating body, and the structural strength and density uniformity of the carbon fiber heating body can be synergistically improved through cooperation of a compression molding method and subsequent densification treatment, so that the carbon fiber heating body is uniform in density and not prone to damage, and the service life of the carbon fiber heating body is prolonged. The heating effect of the carbon fiber heating body is improved, and the service life of the carbon fiber heating body is prolonged; moreover, compared with a vapor deposition method, the mold pressing method is simple and convenient in preparation, the production period is greatly shortened, and the preparation cost is saved.
本申请公开了一种碳纤维发热体及制备方法，包括将酚醛树脂、纤维粉和短切碳纤维按照预设质量比混合，得到混合干料；将所述混合干料注入模具中进行模压，得到碳纤维胚体；对所述碳纤维胚体进行增密处理，得到所述碳纤维发热体。本申请将包括酚醛树脂、纤维粉和短切碳纤维的混合干料模压成型之后进行增密处理，得到碳纤维发热体，通过模压法配合后续的增密处理，能够协同提升碳纤维发热体的结构强度和密度均匀性，使得碳纤维发热体的密度均匀且不易损坏，有利于提升碳纤维发热体的加热效果，延长碳纤维发热体的使用寿命；并且，相比于气相沉积的方法，模压法制备简单方便，大大缩短了生产周期，节省了制备成本。
