Low-cost carbon-ceramic brake material and preparation method thereof
The invention discloses a low-cost carbon-ceramic brake material and a preparation method thereof.The preparation method comprises the steps that carbon fibers are sheared to obtain chopped fibers, the chopped fibers, calcined petroleum coke, phenolic resin, hexamethylenetetramine, nano zirconium silicate powder and vermiculite powder are mixed to obtain a mixture, the mixture is subjected to compression molding to obtain a green body, the green body is carbonized to obtain a carbonized green body, and the carbonized green body is dried to obtain the low-cost carbon-ceramic brake material. The preparation method comprises the following steps: preparing a carbonized green body, carrying out reaction siliconizing on the carbonized green body to obtain a carbon ceramic green body, carrying out silicon impurity removal treatment on the carbon ceramic green body, and finally polishing to obtain the carbon ceramic brake material. The preparation period is short and the cost is low. The prepared carbon-ceramic brake material is stable in friction coefficient, the wear rate is smaller than 0.65 [mu] m/face per time, the brake process is stable, vibration is small, and howling is avoided.
本发明公开了一种低成本的碳陶刹车材料及其制备方法，将碳纤维剪切获得短切纤维，将短切纤维、煅烧石油焦、酚醛树脂、六亚甲基四胺、纳米硅酸锆粉、蛭石粉混合获得混合料，混合料压制成型，获得坯体，将坯体进行碳化处理，获得碳化坯体，将碳化坯体反应渗硅获得碳陶坯体，碳陶坯体再进行硅除杂处理，最后抛光加工即获得碳陶刹车材料，本发明的制备方法，采用树脂模压的方法制备炭/炭坯体。不仅制备周期短而且成本低廉。本发明制备的碳陶刹车材料，摩擦系数稳定，磨损率小于0.65μm/面·次，而且刹车过程稳定，振动小无啸叫。
