Problems solved by technology
In the present invention, the carbon cloth is continuously wound around the needle-punched prefabricated body, and the process method combining chemical vapor infiltration and resin pressure impregnation carbonization is densely made into a carbon / charcoal hot-pressing mold, which can replace graphite in terms of powder metallurgy and ceramic hot-pressing molds Mold, this method can make a mold with good strength at high temperature, but it can't make a hollow structural plate, because the strength at the joints and corners cannot meet the requirements

Disclosed is a carbon-matrix composite-material hollow structural slab. The hollow structural slab consists of an upper face slab, a lower face slab, and intermediate ribs arranged between the upper face slab and the lower face slab at intervals; R angles exist at the connecting places between each rib and the upper and between each rib and the lower face slab; the face slabs and the ribs consist of multiple layers of carbon fiber cloth; the multiple layers of carbon fiber cloth are connected by radial carbon fiber filaments which penetrate into the carbon fiber cloth; the radial carbon fiber filaments and the carbon fiber cloth intersect with each other; and dense carbon matrices are used to fill the spaces between each two adjacent layers of carbon fiber cloth. The hollow structural slab is a hollow structural slab of which the strength and structural strength can be maintained at a certain level in a high temperature range from 1000 DEG C to 2000 DEG C.
Description
technical field [0001] The invention relates to the technical field of a thermal field material for high-temperature furnace welding, in particular to a carbon-matrix composite hollow structural plate. Background technique [0002] For brazing furnaces, it is a contradictory process to braze large-volume workpieces, high temperature generated during welding, and cooling of pressed workpieces at a reasonable speed. Because the workpiece is pressed, it is not conducive to heat exchange, and when the weld is not completely cooled, removing the object that presses the workpiece will affect the quality of the weld. The solution is to use a clip-type pressure plate with its own cooling method. There is a hollow air passage in the pressure plate, which is a hollow structural plate. [0003] It is a big technical problem to manufacture a hollow structural plate that can maintain a certain level of hardness and structural strength at a high temperature of 1000°C to 2000°C. [0004]...
