Abstract

The invention discloses an assorted fiber felt body. The felt body comprises a high-strength carbon fiber assorted layer located on the surface layer and a high-strength ceramic fiber layer located under the high-strength carbon fiber assorted layer, a high-modulus carbon fiber layer is arranged between the high-strength carbon fiber assorted layer and the high-strength ceramic fiber layer, and the high-strength ceramic fiber layer, the high-strength carbon fiber assorted layer and the high-modulus carbon fiber layer are formed through stitching structures. The felt body is a felt-shaped textile with a combined structure taking carbon fiber as the primary material assorted with other fibers. Comprehensive characteristics of different fibers can be achieved by an assorted fiber multi-layerstructure to improve the integrated strength and tearing resistance degree of the felt-shaped textile; a stitching structure multi-layer textile has higher heat-insulation and heat-preserving characteristics and mechanical processing characteristics. By means of the multi-layer felt-shaped structure, the overall tearing resistance degree and the overall heat-insulation and heat-preserving characteristics can be ensured, and the assorted fiber felt body can be extensively applied to heat-preserving parts of high-temperature heating furnaces.

Description

technical field [0001] The invention relates to the technical field of carbon fiber fabrics, in particular to a hybrid fiber mat. Background technique [0002] With the rapid development of the economy, new types of thermal insulation materials used in high-temperature environments are gradually recognized by people, and the stability and functionality of materials used in high-temperature environments are also the focus of people's research. In order to improve the comprehensive performance of current high-performance carbon fiber composite materials, a new type of fiber composite fabric that can be used for thermal insulation materials has been developed. The composite felt fabric prepared by mixing various fibers with carbon fiber as the main material has become the main direction of researcher design. [0003] The insulation material of high-temperature furnaces commonly used in the prior art is mainly single carbon fiber, which is prepared by various processes such as c...
