摘要：精密鑄造所用陶瓷模殼，目前通常采用水玻璃或硅溶膠為粘結劑，通過反復粘漿、淋砂、干燥制成。對于尺寸較大的精鑄件，通常需要通過增加模殼層數(shù)（厚度），來增大模殼的強度。這往往會帶來，操作不便，模殼易開裂等問題。本文通過碳纖維織物增加的方法，開發(fā)一種高強度薄壁精鑄模殼的制作方法，并對其進行工藝參數(shù)優(yōu)化

關鍵詞：硅溶膠   精密鑄造   碳纖維增強

  

Abstract：Ceramic shell mold used in precision casting, now often used sodium silicate and silica sol as binder and is made by repeated mud, pouring sand and drying.  We often increase the mold shell layer (thickness) to increase strength of mold shell for large castings。This will often bring some questions such as inconvenience of the operation, mold shell easy cracking. This paper conducted a high-strength fiber-reinforced thin shell mold Shell technology research and development, and determined the best system shell process parameters.
