Title:
COMPOSITE MATERIAL AND METHOD FOR MANUFACTURING THE SAME, MOLDED ARTICLE, AND INTERMEDIATE BASE MATERIAL
Document Type and Number:
Japanese Patent JP2022191471
Kind Code:
A
Abstract:
To provide a tow prepreg which has low tackiness at room temperature, can be stored in a bobbin state without a backing film by increased tackiness at high temperature, and is suitable for an automatic lamination process in an automatic tape placement device, a method for manufacturing the same, and a fiber-reinforced composite material manufactured using the same.SOLUTION: There are provided a tow prepreg in which a reinforcement fiber bundle is impregnated with a matrix resin composition, wherein a mass ratio of an epoxy resin that is solid at 23°C to an epoxy resin that is liquid at 23°C contained in the matrix resin is 50:50 to 75:25, and the UV thickening magnification is 200-5,000 times; a method for manufacturing the same; and a fiber-reinforced composite material manufactured using the same.SELECTED DRAWING: Figure 1
