High-purity carbon fiber hollow sphere composite material and preparation method thereof
The invention provides a high-purity carbon fiber hollow sphere composite material and a preparation method thereof. The high-purity carbon fiber hollow sphere composite material comprises a hollow layer and a carbon fiber layer; and carbon fibers in the carbon fiber layer are bridged by accumulated carbon atoms decomposed by carbon source gas. Monodisperse polystyrene microspheres are used as a support, then phenolic resin diluent, graphite powder, C2H6O and an amino surfactant are mixed, the outer layers of the monodisperse polystyrene microspheres are wrapped in the carbon fibers, and bridging between the carbon fibers is achieved by decomposing carbon source gas after heating and curing. The technical problems that in the prior art, a high-purity carbon fiber hollow sphere composite material is insufficient in stability, low in high-temperature resistance and low in strength under the vacuum condition are solved.
本发明提供了一种高纯碳纤维空心球复合材料及其制备方法，所述高纯碳纤维空心球复合材料，包括空心层和碳纤维层；所述碳纤维层中的碳纤维，通过碳源气体分解后的堆积碳原子桥接。通过以单分散聚苯乙烯微球为支撑，然后再通过，将酚醛树脂稀释液、石墨粉、C2H6O和氨基表面活性剂混合后，将碳纤维包裹在单分散聚苯乙烯微球外层，加热固化后通过分解碳源气体实现碳纤维与碳纤维之间的桥接。解决了现有技术中的高纯碳纤维空心球复合材料，稳定性不足，在真空条件下耐高温性差，强度低的技术问题。
