| 摘要: |
| 压裂技术是开发非常规油气资源的核心技术,而压裂球的质量又决定该技术的成败。以碳纤维(CF)和聚醚芳酮(PEAK)为原料,采用挤出造粒的方法制备了高性能PEAK/CF复合材料压裂球,并对其微观形貌、热性能及力学性能进行了研究。结果 表明, CF与PEAK结合紧密,当CF质量分数约为25%时, PEAK/CF复合材料的热分解温度大于500 ℃,拉伸强度、剪切强度及弯曲强度的力学性能良好。 |

| Abstract: |
| Fracturing technology is the core technology in development of unconventional resources, and the quality of fracturing ball determines the technical success or failure. The high performance PEAK/Carbon fiber (CF) composite was prepared by extrusion pelletization with the raw material of carbon fiber (CF) and pure PEAK, and the micro-morphology, thermal performance and mechanics property of the composite were studied. The results indicated that the combination of CF and PEAK was tight.When the mass fraction of CF was about 25%, the thermal decomposition temperature of PEAK/CF composite is above 500℃, and the tensile strength, shear strength and flexural strength of the composite were very good. |
