PURPOSE: To obtain a carbon fiber sheet-like material, useful as not only a usual structure but also a reinforcing substrate for a cement-based structure by respectively specifying the pickup of a sizing agent and breaking elongation of a carbon fiber yarn contained in a weaving yarn. CONSTITUTION: This carbon fiber sheet-like material is obtained by applying a sizing agent in an amount of 0.1-0.5wt.% pickup to a carbon fiber yarn contained in a weaving yarn and regulating the breaking elongation of the carbon fiber yarn to >=1.5wt.%, preferably >=1.8%. Thereby, weaving can be carried out while suppressing the occurrence of fuzzes to a small extent even in a small amount of the sizing agent. |
