Materials Criteria Selection and Certification Process for the Body in White in PSA PEUGEOT CITROËN

In order to lighten the body in white with respect to safety and comfort requirements, innovative material solutions have to be developed. In this field, PSA PEUGEOT CITROËN has defined a selection and certification policy in relation to main stages of vehicle development schedule. Then each step of the material certification has to be connected to main vehicle project milestones as follows :

• exploratory stage has to be completed before the concept choice,
• product and process feasibility before the numerical calculations,
• industrial certification before the final drawings. This strategy drives PSA PEUGEOT CITROËN to the use of different levels of high strength steels and aluminium for the body in white.
