Problems solved by technology

For example, the thermoplastic prepreg automatic laying and frontier rapid heating tests carried out by EADS, using laser and hot air as heating sources respectively, were verified by manufacturing wall panel test pieces. The product appearance quality is good, but due to the traditional thermosetting composite material automatic The laying pressure of the laying equipment is low, resulting in insufficient density of the laid thermoplastic composite laminate, which must be cured in an autoclave to meet the load-bearing requirements
Obviously, automatic laying followed by autoclave curing greatly increases the manufacturing cost of thermoplastic composites, significantly reduces manufacturing efficiency, and is not conducive to the further application of thermoplastic composites

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.

Description

technical field [0001] The invention belongs to the manufacturing technology of thermoplastic resin-based composite materials, in particular to a laser in-situ heating-solidification molding device and molding method for thermoplastic composite materials. Background technique [0002] Due to the advantages of high specific strength, high modulus, excellent corrosion resistance and fatigue resistance, carbon fiber reinforced composite materials (CFRP) have surpassed traditional metal materials and become the most used material for new generation aircraft. At present, most of the composite materials used in the aviation industry are thermosetting resin-based composite materials. Compared with thermosetting resin-based composite materials, thermoplastic resin-based composite materials have the following advantages: [0003] (1) High toughness, high fatigue strength, impact damage resistance and impact damage tolerance are higher than thermosetting composite materials; [0004]...
