The continuous fiber composite material is formed in the additive manufacturing mode, so that the problems of complex forming process, more manual and semi-automatic processes, long mold development period, high manufacturing cost and the like in the traditional forming process are solved, intelligent and digital processing and manufacturing can be realized, and the efficiency of part trial manufacturing links is improved.
But the additive manufacturing technology for continuous fiber reinforced composite materials is not perfect at present. The composite material may undergo multiphase variations during additive manufacturing forming, and dimensional errors due to volume shrinkage may affect the forming accuracy of the part. In addition, due to the characteristic of additive manufacturing layer-by-layer superposition layering forming, discretized layering slices break the continuity of the surface of the model, intermediate information is lost, and shape errors and size errors are caused.
