Manufacturing method of mould-pressing needled carbon-carbon crucible support
The invention discloses a manufacturing method of a mould-pressing needled carbon-carbon crucible support, and relates to the technical field of crucible supports. The manufacturing method of a mould-pressing needled carbon-carbon crucible support comprises the following raw materials: carbon fiber felt, carbon fiber cloth and liquid phenolic resin; the preparation method comprises the following steps: needling a carbon fiber felt and carbon fiber cloth through carbon fibers to form a blank body; pouring liquid phenolic resin on the surface of the blank body to enable the liquid phenolic resinto completely permeate into the blank body, and then performing pre-baking; putting the blank body into a processed graphite mold tool, then putting the whole mold into a press vulcanizer to performhot press molding on the blank body, and forming a crucible support by the formed blank body; enabling the crucible support to be subjected to demolding treatment, and then carrying out chemical vapordeposition densification and liquid phenolic resin impregnation carbonization process densification on the crucible support. Liquid phenolic resin is added to the needled crucible support, the crucible support is manufactured in a hot pressing mode, and protrusions, cracking and pricking off are not likely to happen when the crucible support is used under the high-temperature condition.
本发明公开了一种模压针刺碳碳埚托的制作方法，涉及埚托技术领域，该模压针刺碳碳埚托的制作方法，包括原料：碳纤维毡、碳纤维布、液体酚醛树脂；步骤：将碳纤维毡、碳纤维布通过碳纤维针刺，形成胚体；将液体酚醛树脂倒在胚体的表面，使液体酚醛树脂完全渗透胚体，然后进行预先烘制；将胚体放入加工好的石墨模具工装内，随后将整个模具放入到平板硫化机内，以对胚体进行热压成型，成形后的胚体会形成埚托；将埚托进行脱模处理，接着对埚托分别进行化学气相沉积增密以及液体酚醛树脂浸渍‑碳化工艺增密，通过在针刺后的埚托上加入液体酚醛树脂并通过热压的方式制成的埚托，在高温的情况下使用时，不易出现突起、开裂、刺脱。
