Embodiment 1

[0039] Example 1: Welding of carbon fiber reinforced polyetheretherketone resin-based composite (CF / PEEK) plates. A PEEK resin film with a thickness of 0.3mm is placed between the soldering surfaces as solder. Adjust the power of the first servo motor, set the welding pressure to (2.0±0.2)MPa; adjust the output power of the ultrasonic amplifier, and set the welding surface temperature to (420±10)°C. Adjust the moving rate of the moving column to (20±5) mm / s, and move at a constant speed along the welding seam track to complete the welding.

Embodiment 2

[0040] Example 2: Repair of carbon fiber reinforced polyphenylene sulfide resin matrix composite (CF / PPS) plate with delamination damage. Adjust the power of the first servo motor, set the welding pressure to (1.5±0.1) MPa; adjust the output power of the ultrasonic amplifier, and set the welding surface temperature to (350±10)°C. Adjust the moving rate of the moving column to (20±5)mm / s, sweep back and forth to cover all the delaminated areas, and complete the repair.

Abstract

The invention relates to continuous ultrasonic welding equipment for a thermoplastic composite material and application of the continuous ultrasonic welding equipment. The equipment at least comprisesa motion guiding mechanism, an ultrasonic welding mechanism and an industrial controlling unit, wherein the motion guiding mechanism comprises a base with a Y-direction guide rail, a portal frame capable of horizontally moving along the Y-direction guide rail of the base and a cross beam capable of ascending and descending in the Z direction of the portal frame, wherein the ultrasonic welding mechanism comprises a first servo motor, an ultrasonic generator, an amplifier and a welding pressure head which are sequentially connected in the force transmission direction, the first servo motor is arranged on the cross beam and can horizontally move in the X direction along the cross beam, and the industrial controlling unit correspondingly controls moving paths and moving speed in the X direction, the Y direction and the Z direction through control software. According to the continuous ultrasonic welding equipment for the thermoplastic composite material and the application of the continuous ultrasonic welding equipment, welding of the thermoplastic composite material and repairing of the thermoplastic composite material with layering damage can be achieved.

Description

technical field [0001] The invention belongs to the manufacturing technology of thermoplastic resin-based composite materials, in particular to continuous ultrasonic welding equipment for thermoplastic composite materials and its application. 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, but the application range of thermoplastic resin-based composite materials has been expanding in recent years, mainly because thermoplastic resin-based composite materials have the following advantages: [0003] (1) High toughness, high fatigue strength, impact damage resistance and impact damage tolerance are high...
