FIBER SIZING AGENT, FIBER BUNDLES, COMPOSITE INTERMEDIATE, AND FIBER-REINFORCED COMPOSITE MATERIAL

Document Type and Number:

Japanese Patent JP2022001689

Kind Code:

A

Abstract:

To provide a fiber sizing agent having an excellent bundling property.SOLUTION: There is provided a fiber sizing agent comprising a polyurethane resin (U). The polyurethane resin (U) is a polyurethane resin formed by reacting an active hydrogen-containing compound component (A) and an isocyanate component (B). The active hydrogen containing compound component (A) comprises a hydroxyl group-containing polyolefin (A1). The hydroxyl group-containing polyolefin (A1) comprises as constituent monomers ethylene and a C3-8 α-olefin(s). A weight ratio [ethylene/α-olefin(s)] of ethylene and C3-8 α-olefin(s), the constituent monomers of the hydroxyl group-containing polyolefin (A1), is 3/97-65/35.SELECTED DRAWING: None
