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.

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.

A bi-slot tree based tag identification method in RFID systems includes (a) transmitting an inquiry of (n&#x2212;1) bits to each tag at the reader; (b) deciding whether the inquiry of (n&#x2212;1) bits are identical with first (n&#x2212;1) bits of each tag ID when receiving the inquiry of (n&#x2212;1) bits at each tag within a readable range of the reader; (c) transmitting each tag ID by one bit from (n+1)bit to last bit thereof to the reader through different time slots based on nbit value of each tag ID at the tags whose first (n&#x2212;1) bits are identical with the inquiry of (n&#x2212;1) bits; and (d) at the reader, checking whether there is a collision among the tag IDs received from the tags and identifying each tag ID of the tags based on the check result.

A query tree based tag identification method in RFID systems includes: (a) forming a temporary ID for each of the tags; (b) comparing an inquiry of the reader with a portion of the temporary ID in each tag when receiving the inquiry from the reader; (c) if the inquiry and the portion of the temporary ID are identical to each other, transmitting a remainder of the temporary ID in each tag to the reader; (d) if a collision occurs in the step (c), generating new inquiries for storing them in the reader; (e) if there is no collision in the step (c), transmitting an ACK signal to each tag whose temporary ID is identified to receive its real tag ID therefrom; and (f) repeating the steps (b) to (e) until there is no inquiry in the reader.
