Abstract
The invention relates to a laser in-situ heating-solidification forming device and method for a thermoplastic composite material. The forming device comprises a laser heating mechanism, a feeding mechanism and a pressure roller mechanism; the laser heating mechanism and the pressure roller mechanism are separately arranged on the two sides of the feeding mechanism; the feeding mechanism is used for conveying a thermoplastic composite material prepreg tape to be subjected to laying forming; the laser heating mechanism is used for preforming laser heating on the formed surface of the thermoplastic composite material prepreg tape to fuse the formed surface; the pressure roller mechanism comprises a hot pressure roller and a cold pressure roller which are arranged front and back in the formingdirection; the highest working temperature of the hot pressure roller is higher than that of the cold pressure roller; the highest working pressure of the cold pressure roller is higher than that ofthe hot pressure roller; and the hot pressure roller and the cold pressure roller are used for compacting the fused thermoplastic composite material sequentially and enabling the fused thermoplastic composite material to be cooled and solidified quickly during high-pressure cooling.
