Abstract
The invention provides a method for preparing a carbon fibre prefabricated body of a support and heat-insulation part in a thermal field of a monocrystalline silicon furnace. The prefabricated body is prepared into an integrated prefabricated body with a density gradient and a variable structure by controlling the needling density and by adopting different combinations of carbon cloth, carbon fibres or net tyres and fibre configuration in the laying process; the inner section of the prefabricated body serves as in a high-density structural layer which is formed by twisting the carbon cloth and the carbon fibres or the thin net tyres, and the unite layer is paved in a manner of overlapping and needling in a layer-by-layer manner; the outer section of the prefabricated body serves as a low-density functional layer which is formed by paving and needling the thin net tyres layer by layer; and the variable structure of the prefabricated body is realized by controlling the configuration and needling of fibres. The method for preparing the carbon fibre prefabricated body disclosed by the invention is very simple. A prepared carbon-carbon compound material is a material integrating functions and structures and is used for preparing a support and heat insulation integral thermal field material of a monocrystalline silicon growth furnace.
