Weight reduction is one possibility to reduce CO2 emissions. The replacement of metals by thermoplastics in the case of strong mechanical parts often requires more material volume. Therefore the successful implementation of thermoplastic materials often is limited. PEEK polymers show good thermo-mechanical properties and therefore is already used in many transmission applications, e.g. seal rings, thrust washers, bearing shells etc. In the paper the mechanical properties of PEEK, steel, brass and aluminum are compared showing that PEEK strength at yield is comparable to that of brass and aluminum with a better fatigue resistance. Bending load and wall thickness are impacting part stiffness and strength more than material modulus and strength. Thus with PEEK parts weight savings up to 80 % are reachable, as the dimensional difference is smaller compared to modulus difference. A full plastic shift fork has been developed for a DCT gearbox with weight savings of 65 %. It is expected that other meal parts can be replaced realizing extremely high weight saving potentials.
