Disclosed are a partition panel for vehicles and a method of manufacturing the same. The method includes mounting a first prepreg formed to have a shape corresponding to a molding groove on a lower die provided with the molding groove. The molding groove is inclined upwards from the center of a lower portion of the lower die to opposite ends of the lower die. A second prepreg having a sheet type is mounted on the lower die so as to cover the first prepreg. The first prepreg and the second prepreg are integrally molded by placing an upper die on the lower die.

Method of manufacturing partition panel for vehicles

Disclosed are a partition panel for vehicles and a method of manufacturing the same. The partition panel for vehicles includes a panel part formed of a composite material to divide a trunk and the inside of a vehicle from each other and a reinforcement part formed of a composite material, inclined upwards from the center of the lower portion of the panel part to both ends of the panel part, and connected integrally to the panel part.

Partition panel for vehicles and method of manufacturing the same

A vehicular underframe structure may an include a lower panel including a composite material and having a central portion curved upwards along a longitudinal direction thereof; an upper panel including a composite material and combined on the lower panel wherein an undersurface thereof faces an upper surface of the lower panel with an internal compartment formed therebetween; and a rib portion provided in the internal compartment and having a lower rib integrally protruding upwards from the upper surface of the lower panel and an upper rib integrally protruding downwards from the undersurface of the upper panel.

Vehicular underframe structure

A rod stiffener may include a rod molded by a glass fiber reinforced thermoplastic resin, and brackets connected to both ends of the rod, in which properties of a core part forming a center of the rod and an outer part surrounding the core part are formed to be different from each other, and the properties of the core part and the outer part are differentiated by a mixing amount of glass fiber and polypropylene resin including the glass fiber reinforced thermoplastic resin.

Rod stiffener for bumper of car

A car undercover is provided. The car undercover includes: a cover main body installed on a lower end of a front frame carrier; a plurality of mount units formed by being spaced at a predetermined interval in a longitudinal direction on an end of the cover main body, in order to install the cover main body; and a reinforcement rib formed by being protruded in a vertically longitudinal direction on an internal side of the cover main body, in order to reinforce strength, wherein the reinforcement rib includes a stiffener formed by being protruded from the reinforcement rib in a shape opposite to a shape of the reinforcement rib. The car undercover may minimize damage of a pedestrian, by not being broken when colliding with the pedestrian. In addition, the car undercover may minimize damage of internal components, by being broken when colliding with a vehicle.

Car undercover

A bumper back-beam for a vehicle is provided. The bumper back beam includes a glass fiber mat reinforced plastic composite and a carbon fiber reinforced plastic composite disposed within the glass fiber reinforced plastic composite. The glass fiber mat reinforced plastic composite includes polypropylene at about 45 to 60 wt. %, glass fiber at about 35 to 45 wt. %, a crosslink agent at about 0.1 to 10 wt. %, peroxide at 0.1 to 4 wt. %, and an antioxidant at about 0.1 to 4 wt. %. The carbon fiber reinforced plastic composite includes a thermoplastic resin at about 40 to 60 wt. % and a carbon reinforced fiber at about 40 to 60 wt. % arranged in a predetermined direction.
