REINFORCING CARBON FIBER MESH AND PREPARATION THEREOF

摘要

PURPOSE:To provide the subject mesh having good adhesiveness to cement materials and capable of securing excellent workability by holding a carbon fiber bundle coated and impregnated with an epoxy resin containing SiO2 particles having a specific average particle size in a straight line state and simultaneously bonding only intersecting points of the fibers in the bundle to each other. CONSTITUTION:A carbon fiber bundle is coated and impregnated with an epoxy resin emulsion containing SiO2 particles comprising colloidal silica and having an average particle size of 1-100nm and wound on a lattice-like frame in one direction in parallel while being maintained in a straight line state. The frame is rotated at an angle of 90 degree and a carbon fiber bundle is also wound in the direction orthogonal to the first wound fiber bundle. The resultant body is heated and cured in such a state that the intersecting points of the fibers are brought into contact with each other to bond only the intersection portions to each other, thereby inexpensively providing the reinforcing carbon mesh having excellent adhesiveness to cement material cured products. The employment of the mesh as a reinforcing material improves the mechanical physical properties of a carbon fiber-inorganic plate in which the mesh is employed as a reinforcing material.
