specific Embodiment 1
[0025] Install the continuous carbon fiber T300 (manufactured by Toray Corporation, Japan) on the spindle of the creel, then wind the carbon fiber in a wave pattern and pass through the pre-dispersion device, while heating the carbon fiber at a preset temperature of 260°C; Eliminate static electricity due to friction, and then lead the carbon fiber to the wire inlet hole of the radiation melting impregnation device, and the carbon fiber entering the radiation melting impregnation device is also wound around the first tension roller in a wave pattern, and the carbon fiber is led to the second impregnation in the same way Finally, the carbon fiber is led out from the outlet of the secondary impregnation device, and then passes through the traction device and the winding device in turn.
[0026] After the arrangement of carbon fibers is completed, the twin-screw extruder is turned on, and the thermoplastic resin melt is pressed into the radiation melting impregnation mold. The set...
specific Embodiment 2
[0028] The continuous glass fiber (Zhejiang Jushi Group) is installed on the spindle of the creel, and then the glass fiber is wound through the pre-dispersion device according to the wave shape, and the glass fiber is heated at the same time, the preset temperature is 230 ℃; after that, it is passed through the static elimination device Eliminate the static electricity caused by friction, and then guide the glass fiber to the wire inlet hole of the radiation melting and impregnation device, and the glass fiber entering the radiation melting and impregnation device is also wound around the tension roller in a wave pattern, and the glass fiber is guided to the secondary in the same way. The impregnating device finally guides the glass fiber from the outlet of the secondary impregnating device, and passes through the traction device and the winding device in turn.
[0029] After the arrangement of the glass fibers is completed, the twin-screw extruder is turned on, and the thermo...
