Abstract

The invention provides a C / C composite material deposition furnace. Various electrode bars are positioned between a bottom plate of a heat-insulation barrel and a bottom plate of a furnace shell; lower ends of the various electrode bars are respectively connected with a positive pole and a negative pole of a power source; upper ends of the various electrode bars are respectively connected with conductive trays of columns of various workpieces; conduction plates are respectively placed on the tops of the columns; and when the columns are stacked, the conductive trays are positioned on the bottommost layers of the columns, outer ring conductive layers, workpieces, center conductive layers, other workpieces and other ring conductive layers are sequentially placed on the conductive trays from bottom to top until the columns are stacked completely. Conductive bottom plates, conductive rings or sheets, the workpieces and the conduction plates are connected to one another in a gravitational pressing manner, so that a current channel is formed. The problems that a connecting mechanism is complex and is inconvenient to mount by using a clamped type connecting mode in the prior art, expansion and contraction characteristics of the workpieces are different from expansion and contraction characteristics of a clamping mechanism, so that current conduction reliability is poor are solved. The C / C composite material deposition furnace has the advantages of easiness in installation and connection and high current conduction reliability. The structure of the C / C composite material deposition furnace is simplified; and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of preparation of C / C composite materials, in particular to a preparation method of direct heating C / C composite materials. Background technique [0002] The preparation methods of C / C composite materials mainly include indirect heating and direct heating in terms of heating forms. [0003] Indirect heating is a kind of method that uses the resistance of the heating element to make the current flow through the heating element to heat the heating element first, and then use the thermal radiation and conduction of the heating element to reheat the workpiece, so that the workpiece reaches the deposition temperature for deposition. The method has the advantages of high temperature uniformity, many types of workpieces that can be heated, and mature technology, and is widely used in the technical field of C / C composite material preparation. [0004] At present, major international C / C composite material preparati...
