Document Type and Number:
Japanese Patent JP2020192809
Kind Code:
A
Abstract:
To provide a fiber-reinforced resin substrate in which a plurality of resins having different characteristics are strongly composited.SOLUTION: There is provided a fiber-reinforced resin substrate comprising following components [A], [B] and [C]: the component [A] is reinforcing fibers 2; the component [B] is a thermoplastic resin (b) 6; and the component [C] is a thermoplastic resin (c) 7, in which the component [A] is arranged in one direction; a resin region including the component [B] and a resin region including the component [C] are present in the fiber-reinforced resin substrate, the resin region including the component [B] is present on a surface on one side of the fiber-reinforced resin substrate, and a distance Ra(bc) between Hansen solubility parameters of the component [B] and the component [C] satisfies the following formula (1): formula (1) Ra(bc)={4(δDB-δDC)2+(δPB-δPC)2+(δHB-δHC)2}1/2≥8, in which the component [A] included in both resin regions across a boundary surface 9 between the resin region including the component [B] and the resin region including the component [C] is present.SELECTED DRAWING: Figure 2
