连续纤维增强复合材料点阵结构成型工艺研究进展

Continuous fiber reinforced polymer composite (CFRP) has the advantages of high specific stiffness and specific strength, and has been widely used in the fields of aerospace, automotive electronics, defense and military industries. Composite lattice structures have high structural efficiency and are widely used in lightweight sandwich structures,which play a key role in carrying structural loads. However,due to its complex structure,large-scale integrated manufacturing of lightweight lattice structures remains a technical challenge for researchers. This paper summarizes the forming process of continuous fiber reinforced composites 2D lattice and 3D lattice structures. Aiming at different forming processes of lattice structure,this paper analyzes the forming process,process characteristics and structural damage forms,and further comprehensively compares the advantages and disadvantages of each forming process. Finally,the future development of the continuous fiber reinforced composite lattice structures forming process is prospected.
