Abstract:
A fiber-reinforced resin molded body having damping properties, said molded body being a laminate that comprises fiber-reinforced resin layers prepared by impregnating a woven fabric with a resin and damping layers formed of a synthetic resin, wherein: a layer positioned at the center in the thickness direction of the laminate is a central fiber-reinforced resin layer; upper and lower damping layers are disposed so as to sandwich the central fiber-reinforced resin layer; outer fiber-reinforced resin layers are respectively provided outside the damping layers; the thickness (X) from the central face of the laminate that is the central face in the thickness direction of the laminate to the interface between the central fiber-reinforced resin layer and each damping layer and the thickness (Y) from the central face of the laminate to the surface of the laminate satisfy the requirement that X/Y is 0.19-0.89; and the sum (d) of the thicknesses of all of the damping layers contained in the laminate and the overall thickness (D) of the laminate satisfy the requirement that d/D is 0.02-0.18. Thus, a fiber-reinforced resin molded body having damping properties, which has a high strength and excellent damping properties, and an automobile part, which comprises the same as a constituting member, can be provided.
