Vibration-damping properties fiber reinforced resin molded body and automotive parts using the same

摘要

The resin A vibration damping fiber reinforced resin molded body is a laminate of the fiber reinforced resin layer made by infiltrating woven synthetic resin of the damping layer, centered with respect to the thickness direction of the laminate layers is a central fiber-reinforced resin layer, it is provided damping layer of the vertical so as to hold it, respectively the outer fiber-reinforced resin layer provided on the outside, and, in the central plane in the thickness direction of the laminate the thickness from one laminate center plane to the interface between the central fiber-reinforced resin layer and the damping layer (X), the thickness of up to laminate the surface of the laminate center plane (Y) is, X / Y = 0 satisfy the relation of .190.89, further, the total thickness of all of the damping layers included in the laminate and (d-), the laminate total thickness (D) is, d / D = 0. satisfy the relationship of 02-.18. Therefore, excellent vibration damping property and having high strength, it is possible to provide vibration damping fiber reinforced resin molded product, and the automotive part comprising it as a constituent member
