Laser-weldable carbon fiber modified PEEK material and preparation method thereof

The invention provides a laser-weldable carbon fiber modified PEEK material and a preparation method thereof, and relates to the field of special engineering plastics. The material mainly comprises the following components in parts by weight: 60-120 parts of first PEEK resin, 15-30 parts of second PEEK resin, 10-20 parts of carbon fiber, 5-10 parts of low dielectric glass fiber, 5-10 parts of hollow glass beads, 1-2 parts of light-transmitting black pigment, 1-2 parts of compatilizer, 1-2 parts of heat stabilizer, 1-2 parts of antioxidant and 1-2 parts of lubricant. The preparation method comprises the following steps: respectively adding the raw materials weighed in parts by weight into a twin-screw extruder from three feeding hoppers of the twin-screw extruder, and carrying out melting reaction, extrusion, cooling, pelletizing and drying to obtain the product. The prepared carbon fiber modified PEEK material has the characteristics of good light transmission, high welding strength and the like, secondary pr
