Impregnation composite liquid for carbon-carbon composite material and preparation process of impregnation composite liquid
The invention discloses a dipping composite liquid for a carbon-carbon composite material and a preparation process thereof, a carbon-carbon fiber blank is soaked in the dipping composite liquid and then is heated under a high-pressure condition to form a dried carbon-carbon fiber blank, and the dried carbon-carbon fiber blank is carbonized at a high temperature to form the carbon-carbon composite material. The dipping composite liquid is prepared from the following components in parts by weight: 100 parts of polyamide acid, 8 to 15 parts of diglycidyl phthalate epoxy resin, 300 to 500 parts of diluent, 40 to 70 parts of silicon carbide, 30 to 50 parts of carbon powder, 3 to 6 parts of polytetramethyl styrene and 0.1 to 0.3 part of aluminate coupling agent. According to the invention, the interlaminar shear strength of the carbon fiber blank is greater than 45 MPa and the compressive strength is greater than 220 MPa by dipping the composite liquid.
本发明公开了一种用于碳碳复合材料的浸渍复合液及其制备工艺，碳碳纤维坯料经浸渍复合液浸泡处理后，在高压条件下加热后形成烘干碳碳纤维坯料，此烘干碳碳纤维坯料在高温下碳化形成所述碳碳复合材料，所述浸渍复合液由以下重量份的组分组成：聚酰胺酸100份、邻苯二甲酸二缩水甘油酯环氧树脂8~15份、稀释剂300~500份、碳化硅40~70份、碳粉30~50份、聚四甲基苯乙烯3~6份、铝酸酯类偶联剂0.1~0.3份。本发明浸渍复合液使得碳碳纤维坯料的层间剪切强度大于45MPa，抗压强度大于220 MPa。
