Claim 0:
1. A reinforcing material for use with a thermoplastic resin, the reinforcing material comprising:
coated glass flakes; and
coated glass strands,
wherein each of the coated glass strands includes a plurality of glass filaments and a coating formed on the glass filaments,
the glass flakes have a thickness of 0.1 to 4.0 μm,
the glass flakes have an average particle diameter of 10 to 800 μm,
the coatings on the glass flakes contain a first glycidyl group-including resin and aminosilane,
the coatings on the glass flakes contain the first glycidyl group-including resin in an amount of 30% to 95% by mass when a total amount of the first glycidyl group-including resin and the aminosilane, corresponds to 100% by mass,
the coated glass flakes have an ignition loss of 0.1% to 2.0% by mass measured pursuant to JIS R3420 (2013),
the coatings on the glass filaments contain a second glycidyl group-including resin, aminosilane, and a urethane resin,
the coatings on the glass filaments contain the second glycidyl group-including resin in an amount of 10% to 90% by mass, the aminosilane in an amount of 0.1% to 40% by mass, and the urethane resin in an amount of 1% to 50% by mass when a total amount of the second glycidyl group-including resin, the aminosilane, and the urethane resin corresponds to 100% by mass, and the coated glass strands have an ignition loss of 0.1% to 2.0% by mass measured pursuant to JIS R3420 (2013); and
wherein the reinforcing material has a mass ratio of coated glass flakes to coated glass strands of 1 to 15/25 to 70.
