Abstract
The present application relates to a sizing agent composition, a carbon fiber material and a composite material. The sizing agent composition comprises specific compositions, thereby producing a sizing agent having emulsion droplets with specific diameter. The sizing agent has excellent emulsion stability, and it can efficiently improve hygroscopicity and dimensional stability of the carbon fiber material. Besides, the sizing agent can improve bonding properties between the carbon fiber material and resin matrix, therefore enhancing properties of the composite material.
