Optimization of Carbon Fiber Allocation and Orientation to Develop Low-cost CFRTP

: In this study, we proposed an optimization method for carbon fiber allocation and orientation to reducethecost ofCFRTP.CFRTP iseffectivein reducing theweight oftransporta-tion equipment.However,thehigh materialcost ofCFRTP possesses a problem for the practical applicationofCFRTP.Therefore,wefocusedontheallocationandorientationofcarbonfibersthat affect the material properties of CFRTP to develop low cost and high stiffness CFRTP using minimal carbon fibers. The allocation of carbon fiber is determined by topology optimization employed in theproposed optimization method.Similarly,theorientation ofcarbon fiberisdeter-mined bytheprincipalstress.Thus,high stiffnessCFRTP with fewerfiberscan beobtained using theproposed optimization method
