Preparation method and application of chopped carbon fiber insulation felt
The invention relates to the technical field of carbon composite materials, in particular to a preparation method and application of a chopped carbon fiber insulation felt. The preparation method comprises the following steps: adding a cross-linking agent and a monomer into water, uniformly stirring, and adding an initiator to obtain a mixed solution 1; adding polyacrylamide into water, uniformly stirring to obtain a polyacrylamide solution, and uniformly stirring the polyacrylamide solution with the mixed solution 1 in the step S1 to obtain a mixed solution 2; adding water-soluble sugar into water, and uniformly stirring to obtain a water-soluble sugar solution; mixing chopped fibers, the water-soluble sugar solution and the mixed solution 2 to obtain a paste material; placing in a mold, drying, and then cooling and demolding to obtain a prefabricated blank body; and sequentially carrying out pre-carbonization and carbonization on the prefabricated blank body to obtain the low-density carbon-bonded carbon fiber composite material. The method is simple and easy to implement, and the prepared material has the excellent properties of low density, high strength, high purity, good heat insulation performance, porosity and the like.
本申请涉及碳复合材料技术领域，特别是涉及一种短切碳纤维保温毡的制备方法与应用。所述制备方法，包括：将交联剂、单体加入到水中搅拌均匀，加入引发剂，得到混合溶液1；将聚丙烯酰胺加入到水中搅拌均匀，得到聚丙烯酰胺溶液，将其与步骤S1的混合溶液1搅拌均匀，得到混合溶液2；将水溶性糖类加入到水中搅拌均匀，得到水溶性糖溶液；将短切纤维、水溶性糖溶液、混合溶液2混合，得到糊料；置于模具中，进行干燥，然后冷却脱模，得到预制胚体；对预制胚体依次进行预炭化、炭化，得到低密度碳粘结碳纤维复合材料。采用本方法简便易行，制备出的材料兼具低密度、高强度、纯度高、隔热性能好、多孔率等优异性能。
