Efficient preparation process of short fiber hard thermal insulation composite material
The invention provides a high-efficiency preparation process of a short-fiber hard thermal-insulation composite material. The high-efficiency preparation process comprises the following steps: immersing carbon fibers of which the raw material is short fibers into a modifier for surface treatment, and then sequentially carrying out metal modification, carbon layer deposition and inorganic matter layer coating on the surface, carbon fibers and inorganic materials are subjected to composite hot pressing, then high-temperature graphitization treatment is carried out, and the short fiber hard heat preservation composite material is obtained. According to the process, the connection strength between the short fibers and the inorganic material can be improved, the mechanical performance of the composite material is improved, the graphitization degree is higher, and the good heat preservation performance is achieved.
本发明提供一种短纤维硬质保温复合材料的高效制备工艺：将原料为短纤维的碳纤维浸入改性剂中进行表面处理，然后依次在表面进行金属修饰，沉积碳层以及包覆无机物层；将碳纤维和无机材料复合热压，然后进行高温石墨化处理，即得短纤维硬质保温复合材料。本工艺能够提高短纤维和无机材料之间的连接强度，提高复合材料的机械性能，并且石墨化程度更高、具有良好的保温性能。
