This work analyses the stress distribution in injected molded carbon fiber (CF) reinforced poly-ether-ether-ketone (PEEK) gears. The actual fiber orientation was assessed by simulation of the injection molding process. Welding line locations were identified for different injection configurations and dimension stability was compared. Fiber distribution was mapped to a finite element model in order to obtain the local constitutive behavior. The most critical parts in the gear are identified and their correlation with the obtained microstructure was discussed.
