用气相氧化法对碳纤维进行表面处理

SURFACE TREATMENT AND INTERFACE EFFECT OF CARBON FIBERS

摘要: 碳纤维的表面处理方法很多。我们选择了行之有效的气相氧化法。实验结果表明,碳纤维经气相氧化处理后,不仅可使复合材料的层间剪切强度提高36—56%,而且也可使碳纤维本身的抗拉强度提高11—31%。所以,本法效果显著,可与碳纤维生产线相配套。

Abstract: In the present study we used gaseous oxidative procedure which carried out, with simple equipment,easy operation and likable with manufacturing line of carbon fibres.By using gaseous oxidation of carbon fibres an inter-laminar shear, strength (ILSS) of the carbon fibre reinforced plastic(CFRP) Can be increased by 36-56%.This is attributed to the increased concentration of chemical fuactional groups on the fibre surface.It was found that tensile serength of carbon fibre can be increased by 11-31% because of the removal of surface flaws.
