Automotive fenders is one such example where specialized thermoplastic material Noryl GTX* (blend of Polyphenyleneoxide (PPO) + Polyamide (PA)) has successfully replaced metal by meeting functional requirements. The evolution of a fender design to fulfill these requirements is often obtained through a combination of unique material properties and predictive engineering backed design process that accounts for fender behavior during the various phases of its lifecycle. This paper gives an overview of the collaborative design process between Mitsubishi Motors Corporation and SABIC Innovative Plastics and the role of predictive engineering in the evolution of a thermoplastic fender design of Mitsubishi Motors Corporation's compact SUV RVR fender launched recently. While significant predictive work was done on manufacturing and use stage design aspects, the focus of this paper is the design work related to identifying support configuration during the paint bake cycle.

Worldwide involvement in Global Technical Regulation (GTR) discussion shows the increasing importance of pedestrian safety as a global concern. Vehicle front styling plays an important role in vehicle to pedestrian impact. Front styling can change the pedestrian kinematics and injury levels during an impact. Key elements of bumper front are Fascia, Upper & Lower Grille, Hood, spoiler or undertray, bumper beam and height of these components from ground level, determine the vehicle aggressiveness for pedestrian safety. This paper presents an approach to diagnose the vehicle front aggressiveness for pedestrian leg impact. Eight different vehicle bumper front configurations from ‘minis’ to ‘sedans’ are studied for lower leg impact cases, to understand the bumper stiffness profile (stiffness in upper, middle and lower load path).
