Sizing agent composition, carbon fiber material and composite material

The invention relates to a sizing agent composition, a carbon fiber material and a composite material. The sizing agent composition comprises a specific composition, so that a sizing agent with a specific droplet particle size can be prepared. The prepared sizing agent has good emulsification stability, and can effectively improve the moisture absorption rate and the size change rate of the carbon fiber material. In addition, the sizing agent can improve the bonding property of the carbon fiber material and the resin base material, so that the property of the prepared composite material is improved. 本发明有关于一种上浆剂组成物、碳纤维材料与复合材料。此上浆剂组成物包含特定组成物，而可制得具有特定液滴粒径的上浆剂。其中，所制得的上浆剂具有良好的乳化安定性，且可有效改善碳纤维材料的吸湿率与尺寸变化率。另外，此上浆剂可提升碳纤维材料与树脂基材的结合性，而提升所制得复合材料的性质。
