Research progress of process and structures optimization for 3D printed continuous fiber-reinforced polymers
Continuous fiber-reinforced polymers(CFRP)has been broadly applied in the aerospace engineering due to its excellent specific strength,specific stiffness,designability and lightweight fea-ture.The development of 3D printing has changed the manufacturing process of CFRP structures,which makes the free form of complex structures possible and provides more design space for ad-vanced structural materials.In order to give full play to the performance advantages of CFRP and the flexibility of 3D printing process,and achieve innovative structural design and performance improve-ment,researchers explored the solutions of design and manufacturing integration for 3D printing CFRP from the aspects of material performance and structural design,respectively.In this paper,the development of properties analysis,process improvement and structure optimization of CFRP is re-viewed systematically.Various multi-scale optimization methods of CFRP are summarized and illus-trated,the development trend of real-time,functional and intelligent structural design method of ad-vanced materials in the future is discussed and prospected.
