SYSTEMS AND METHODS FOR ADDITIVELY MANUFACTURING COMPOSITE PARTS

摘要

A system (100) for additively manufacturing a composite part (102) comprises a delivery guide (112), movable relative to a surface (114). The delivery guide (112) is configured to deposit at least a segment (120) of a continuous flexible line (106) along a print path (122). The continuous flexible line (106) comprises a non-resin component (108) and a thermosetting-resin component (110). The thermosetting-resin component (110) comprises a first part (253) and a second part (255). The system (100) further comprises a first resin-part applicator (236), configured to apply a first quantity of the first part (253) to the non-resin component (108), and a second resin-part applicator (237), configured to apply a second quantity of the second part (255) to the first quantity of the first part (253) of a thermosetting resin (252), applied to the non-resin component (108). The system (100) also comprises a feed mechanism (104), configured to pull the non-resin component (108) through the first resin-part applicator (236) and the second resin-part applicator (237), and to push the continuous flexible line (106) out of the delivery guide (112).
