Manufacturing process of high-strength carbon-carbon composite material
The invention discloses a manufacturing process of a high-strength carbon-carbon composite material, which comprises the following steps of: soaking a carbon-carbon fiber blank in dipping composite liquid, 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; drying the soaked carbon fiber blank under a vacuumizing condition; drying the dried carbon fiber blank under a vacuumizing condition; and heating the dried carbon fiber blank to 200 DEG C under the condition of 4-6MPa, preserving heat for 6-10 hours, and then naturally cooling. The interlaminar shear strength of the obtained carbon fiber blank is greater than 45 MPa, and the compressive strength is greater than 220 MPa.
本发明公开了一种高强度碳碳复合材料的制造工艺，包括以下步骤：将碳碳纤维坯料浸泡于浸渍复合液中，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；将浸泡后的碳碳纤维坯料在抽真空的条件下烘干；将烘干碳碳纤维坯料在抽真空的条件下烘干；将烘干碳碳纤维坯料在4~6MPa的条件下升温到200℃，保温6~10小时后自然冷却。本发明获得的碳碳纤维坯料的层间剪切强度大于45MPa，抗压强度大于220 MPa。
