Continuous fiber composite material additive manufacturing Z-direction reinforcing method and manufacturing equipment

Abstract

The invention provides a continuous fiber composite material additive manufacturing Z-direction reinforcing method and a manufacturing equipment, and belongs to the field of additive manufacturing. The method comprises the following steps of establishing a three-dimensional model of a preformed continuous fiber reinforced composite material piece; layering the three-dimensional model by using layering software to obtain a lamination data file; converting the lamination data file into a forming path driving signal file which can be directly identified by the additive manufacturing equipment; and printing according to the driving signal file. The continuous fiber composite material additive manufacturing Z-direction reinforcing method and the manufacturing equipment aim to solve the technical problems in the prior art.
