Abstract: The present disclosure provides a body structure for a vehicle capable of improving a vibration damping effect by a damping member while preventing an increase in an application amount of the damping member and a shape change of a component. Embodiments include a body structure for a vehicle in which a first bonded surface of a first body component and a second bonded surface of a second body component are bonded via a damping member, with which a portion between the first bonded surface and the second bonded surface is filled. The first bonded surface of the first body component has a vertical wall extending toward the second bonded surface or away from the second bonded surface. The portion between the first bonded surface and the second bonded surface is filled with the damping member such that the damping member contacts the vertical wall.

Abstract: A reinforcing body is disposed in a closed cross sectional portion constituted by one or more vehicle body components. The reinforcing body is provided with a joining portion to be joined to the vehicle body components. The joining portion includes hard connecting portions connected to the vehicle body components in an abutting state, and a soft connecting portion connected to the vehicle body components via a vibration damping member. The storage shear rigidity (KB′) of the vibration damping member is set in the range: 800 N/mm

Abstract: A vehicle upper structure reduces noise in a cabin by preventing vibration of a roof panel while avoiding an increase in manufacturing cost and an increase in vehicle weight. A vehicle includes a roof panel, a front header, a ceiling, and a vibration damping member. The front header extends in a vehicle width direction on an inner side of the cabin from the roof panel. The ceiling covers the roof panel from the inner side of the cabin. The vibration damping member is fixed to an upper surface of the ceiling. The vibration damping member is arranged between a sun visor fixed portion and a gusset fixed portion in the vehicle width direction and near the front header. The vibration damping member has at least two resonance frequencies and is configured such that one resonance frequency thereof is substantially the same as a resonance frequency of the ceiling.

Abstract: Provided is a fiber reinforced plastic member made by a braiding technique to obtain high rigidity and superior vibration damping performance under a bending load. A reinforcing member made of carbon fiber reinforced plastic resin extends in a specific direction along an axis of the reinforcing member and includes a carbon fiber braided structure. The carbon fiber braided structure has a structure in which a plurality of axial yarns, a plurality of first braid yarns, and a plurality of second braid yarns are braided. A plurality of first braid yarns are wound to intersect the axis at a first braid angle. A plurality of second braid yarns are wound to intersect the axis at a second braid angle. The first braid yarns and the second braid yarns intersect each other. The reinforcing member has a region approximately in the longitudinal middle where the first braid angle and the second braid angle of the first braid yarns and the second braid yarns take values larger than in other region regarding the longitudinal direction.
