  7. 5. Ageing behavior of plastics used in automotive fuel systems

    Författare :Xin-Feng Wei; Mikael S. Hedenqvist; Richard Olsson; Ulf W Gedde; Pieter Gijsman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive; Ageing; Polyamide; Diesel; Biodiesel; Diffusion; Oxidation; Plasticizer migration; Mechanical properties; Fracture behavior.; Fordon; Åldrande; Polyamid; Diesel; Biodiesel; Diffusion; Oxidation; Mjukgöraravgång; Mekaniska egenskaper; Brottegenskaper;

    Sammanfattning : The increase in service temperature and the use of biobased fuels, such as biodiesel, have raised concerns on the short/long-term performance of plastic components used in automotive fuel systems.In this work the ageing behavior of unreinforced and glass-fibre reinforced polyamide 12 (PA12), exposed to three different fuels (petroleum diesel, biodiesel, and a mixture of these (80/20)) at high temperature, was investigated.
