摘要:
There is provided a fiber-reinforced composite material is constituted by reinforcing fibers with an average fiber length of 5 mm to 100 mm and a thermoplastic resin, in which in a viscoelastic characteristic that is defined by following formulas (1) and (2), an average value in a range of −25° C. of the melting point of a matrix resin to +25° C. of the melting point of a matrix resin satisfies following formula (3): tan δ=G″/G′ (1) tan δ′=Vf×tan δ/(100−Vf) (2) 0.01≦tan δ′≦0.2 (3) wherein G′ represents a storage modulus (Pa) of the fiber-reinforced composite material, G″ represents a loss modulus (Pa) of the fiber-reinforced composite material, and Vf represents a volume fraction (%) of the reinforcing fibers in the fiber-reinforced composite material.
