Document Type and Number:
Japanese Patent JP6984821
Kind Code:
B2
Abstract:
To provide a core material whose area to be bent is hard to deform when bending a tubular body formed by a fiber-reinforced thermoplastic resin.SOLUTION: A core material 6 for bending includes at least one kind of linear member whose shape of a cross section orthogonal to the longitudinal direction is any one of a hollow circle, an ellipse and a polygon; and is formed by bundling a plurality of linear members 6a formed by, for example, PEEK which is hard to plastically deform by heating than, for example, a polyamide resin which forms a fiber-reinforced resin tubular body 1.SELECTED DRAWING: Figure 3
