Preparation method of carbon ceramic green body, carbon ceramic green body and carbon ceramic brake pad
The invention provides a preparation method of a carbon ceramic green body, the carbon ceramic green body and a carbon ceramic brake pad, and relates to the technical field of brake pads. The preparation method of the carbon ceramic green body comprises the following steps: placing a carbon fiber preform in an infiltration solution, and carrying out ultrasonic treatment to obtain a modified carbon fiber preform; wherein the infiltration liquid comprises organic silicon modified phenolic resin, siloxane modified polyimide resin, silicon carbide, graphite and silicon dioxide; and performing carbonization treatment and high-temperature sintering on the modified carbon fibers to obtain the carbon ceramic green body. According to the preparation method, a good infiltration effect and a good dispersion effect are achieved on the carbon fibers through the ultrasonic cavitation effect, the combining capacity of the carbon fibers and resin is remarkably improved, and therefore the composite material with more excellent performance is prepared, and the carbon ceramic brake pad high in mechanical strength, resistant to high temperature and resistant to friction is prepared.
本发明提供了一种碳陶胚体的制备方法、碳陶胚体及碳陶刹车片，涉及刹车片技术领域。所述碳陶胚体的制备方法包括以下步骤：将碳纤维预制体置于浸润液中，进行超声处理，得到改性碳纤维预制体；其中，所述浸润液包括有机硅改性酚醛树脂、硅氧烷改性聚酰亚胺树脂、碳化硅、石墨和二氧化硅；将改性碳纤维预制进行碳化处理和高温烧结，得到所述的碳陶胚体。本发明所述制备方法通过超声空化作用对碳纤维有良好的浸润效果和分散作用，显著地提高碳纤维与树脂的结合能力，从而制备性能更优异的复合材料，由此制备得到机械强度高、耐高温、耐磨擦性能的碳陶刹车片。
