Description

Technical Field

[0001] The utility model relates to the technical field of placing carbon fiber crucible preforms, and particularly relates to a placing rack for carbon fiber crucible preforms. Background Art

[0002] Carbon fiber is mainly composed of carbon elements, and has characteristics such as high temperature resistance, anti-friction, heat conduction and corrosion resistance. Its shape is fibrous, soft, and can be processed into various fabrics. Due to the preferred orientation of its graphite microcrystal structure along the fiber axis, it has high strength and modulus along the fiber axis direction. The density of carbon fiber is small, so its specific strength and specific modulus are high. The main use of carbon fiber is as a reinforcing material to be compounded with resins, metals, ceramics, carbon, etc. to manufacture advanced composite materials. The specific strength and specific modulus of carbon fiber reinforced epoxy resin composite materials are the highest among existing engineering materials.

[0003] A crucible is a cup-shaped vessel used in a laboratory for high-temperature heating of solids.

[0004] Due to the good high-temperature resistance of carbon fiber, through certain material composite design and preparation processes, it can be used as a carbon-carbon crucible product for single crystal furnaces. The carbon-carbon crucible product for single crystal furnaces is a preform woven from carbon fibers with multiple pores, and then the pores in the carbon fiber preform are filled by chemical vapor deposition or impregnation resin carbonization to increase its density. The carbon fiber preform can be designed according to the shape and usage requirements of the actual application component, and its performance has a great impact on the usage performance of the final product.

[0005] In the prior art, the carbon fiber preform without hardening treatment has a soft texture and is prone to deformation during furnace loading and handling, seriously affecting the subsequent machining. Content of the Utility Model

The limiting groove is opened on the left side surface of the stud.

[0010] Preferably, two fork grooves are symmetrically opened on the front surface of the base.

[0011] Preferably, the fixing component includes a spring rod fixedly connected to the front surface of the inner wall of the moving groove.
