Title:
METHOD FOR MANUFACTURING FIBER-REINFORCED BASE MATERIAL, AND METHOD FOR MANUFACTURING SHUTTER BLADE
Document Type and Number:
Japanese Patent JP2021134306
Kind Code:
A
Abstract:
To provide a fiber-reinforced base material which hardly causes warpage, and a shutter blade having high accuracy.SOLUTION: A method for manufacturing a fiber-reinforced base material includes: a first step of preparing first sheet materials 1 in which reinforcement fibers oriented in one direction are embedded in a thermoplastic resin, and a second sheet material 2 containing a thermoplastic resin; a second step of interposing the second sheet material 2 between the two first sheet materials 1 in which the orientation directions of the reinforcement fibers are aligned, and arranging the sheet materials on a lower press die 100; and a third step of making an upper press die 200 face the lower press die 100, bringing the lower press die 100 and the upper press die 200 into close contact with each other while heating the press dies and thereby melting the thermoplastic resin of the first sheet materials 1 and the thermoplastic resin of the second sheet material 2, integrating the two first sheet materials 1 and the second sheet material 2, and obtaining a fiber-reinforced base material 3.SELECTED DRAWING: Figure 1
