摘要： Provided is a reinforced composite material, comprising: a laminate of a plurality of fiber reinforced sheets; and a surface material on at least one surface of the laminate. Each of the fiber reinforced sheets comprises: a fiber reinforcing material having orientation; and a resin base material. The plurality of fiber reinforced sheets comprise: at least one first fiber reinforced sheet including a fiber reinforcing material having directionality in a first direction having an angle of +1° to +44° with respect to a reinforcement required direction; and at least one second fiber reinforced sheet including a fiber reinforcing material having directionality in a second direction having an angle of −1° to −44° with respect to the reinforcement required direction. The surface material comprises a metal sheet having a mesh structure. Also provided is an article including the reinforced composite material.
