Title:
COMPOSITE RAW MATERIAL BINDING CARBON FIBER FABRIC AND ELASTIC HIGH MOLECULAR COMPOUND, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2019181717
Kind Code:
A
Abstract:
To provide a composite raw material having strong binding force of a carbon fiber and an elastic high molecular compound such as a rubber, having toughness and excellent in flexibility, and a manufacturing method therefor.SOLUTION: A composite raw material 1 is heating treated and having a carbon fiber fabric 2 to which an additive is impregnated and an elastic high molecular compound 3 conjugated. The carbon fiber fabric has a structure of plain weave, twill, stain weave, or lattice weave. The elastic high molecular compound is one using a structure of an ethylene propylene rubber, a butyl rubber, an acrylnitrile rubber, or a silicone rubber. At least one layer of the carbon fiber fabric is sandwiched between a plurality of elastic high polymer compounds. The composite raw material is obtained by heating treating the carbon fiber fabric, impregnating the heating treated carbon fiber fabric in an adhesive liquid containing an isocyanate compound and an ethylene glycol compound, drying treating the carbon fiber fabric impregnated in the adhesive liquid, and press molding and crosslinking molding the dry treated carbon fiber fabric and the elastic high molecular compound.SELECTED DRAWING: Figure 1
