Repairing assessment on damageability of a vehicle is done by analyzing the damage itself and repairing costs for the damage that collisions caused. Korea, as it is in European countries, uses RCAR low speed collision test as a standard when analyzing. RCAR has announced its new plan to implement a new set of tests that includes bumper barrier tests in addition to existing structure tests. In order to adjust for the new RCAR test, it is more than necessary to adopt crush box technology; also, strength of bumper beams need to be brought up to match that of the North American version. In this report, a new system developed by introducing a new design to meet the RCAR requirement has been analyzed. The new structure which consists of crash boxes installed on existing performance-proved North American GMT beam has been assessed. All the adjustment and new development have been initiated in purpose of passing newly erected RCAR test.

In order to meet the new European regulation ECE 17.07, automobile makers are required to prepare for a high performance seating system. This paper describes the development of a seating system with the 60:40 and 50:50 fold-down rear seat backs made of GMT (Glassfiber Mat Thermoplastic) for the ECE 17.07. GMT-RD( random mat grade) composite was used as the seat back material because of it's high strength and toughness. Through the static and dynamic structure analysis, we have optimized the seat back design including rib pattern, hinge structure, and so on. This newly developed GMT seat-back meets the above mentioned requirements with significant weight savings when compared with traditional steel seat back.
