Abstract: A vehicular center pillar includes a pillar outer panel including an upper outer portion and a lower outer portion divided by a beltline, a pillar inner panel including an upper inner portion and a lower inner portion divided by the beltline, and an upper reinforcing member disposed between the upper outer portion and the upper inner portion, and having a flange extending toward a door opening, wherein the upper outer portion has a first flange extending toward the door opening, and the flange of the upper reinforcing member is fixed to the first flange of the upper outer portion.

Abstract: A vehicle body side reinforcement assembly includes a first side reinforcement panel; an inner center pillar coupled to the first side reinforcement panel and to a floor support forming a lower portion of a vehicle body; and a second side reinforcement panel coupled to the first side reinforcement panel, the inner center pillar, and the floor support to form a closed structure at a lower portion of the side of the vehicle. This structure improves vehicle body performance during a side collision by transferring the collision load to the floor support, resulting in improved safety performance. In addition, the assembly minimizes the number of necessary parts and allows for low-cost assembly methods, such as spot welding, thereby reducing production costs and increasing marketability.

Abstract: A method of sealing a panel joint includes steps of: attaching a forming material made of resin and reinforced fiber to a joint as a bonded end of a plurality of panels such that the joint is surrounded with the forming material; coupling a cover back to surround the forming material, and sealing a coupled end of the cover back using a sealing tape; mutually compressing the reinforced fiber and the resin of the forming material, while the reinforced fiber is impregnated with the resin, using compressive force of the cover back generated by introducing air into a nozzle connected to the cover back; and hardening the resin and removing the cover back and the sealing tape.

Abstract: A B-pillar unit for a vehicle is provided. The B-pillar unit includes a B-pillar that is connected to a vehicle body. In particular, the B-pillar includes a roof surface, a left surface, a right surface and a floor surface that are connected in a substantially circular shape.

Abstract: A CFRP plate having a steel plate wherein a weld nut is welded is integrally stacked, and a manufacturing method are provided. The CFRP plate is formed by interposing a steel plate having a weld nut welded to a lower surface between two adjacent CFRP layers. A foam is interposed between a layer when the steel plate is disposed and a layer below the layer when the steel plate is disposed. The guide pins are fitted into the steel plate, a second layer, and the foam, forming an aperture in a portion of a second layer where the weld nut is positioned. A grove is formed accommodating the weld nut in the foam positioned below the aperture. A resin is injected when a temporary bolt is fitted into the weld nut, and the temporary bolt is removed after the resin is injected.

Abstract: A self-piercing rivet which reduces damage of a composite part and enhances bonding capability by suppressing galvanic corrosion is provided. The self-piercing rivet includes a repair resin that is disposed in a space formed within the rivet and a passage that is formed between an inner surface forming the space and an outer surface of the rivet and through which the repair resin flows.
