Abstract

The invention discloses a high-frequency vibration continuous fiber prepreg production device, relates to the technical field of continuous fiber prepreg production, and is mainly used for solving the problem that prepregs are difficult to soak in methods or equipment adopted for continuous fiber prepreg production at present. The primary structure of the device is that the device comprises a creel, a guide roller group, a yarn spreading roller group, a drying oven, an extrusion forming mold group, an ultrasonic impregnation module group, an extrusion roller group, a cooling platform, a pull roll group and a winding mechanism which are arranged in sequence. According to the high-frequency vibration continuous fiber prepreg production device provided by the invention, continuous fibers before being coated with resin are vacuumed through a negative pressure vacuum channel, and ultrasonic vibration is applied to the continuous fibers coated with the resin through ultrasonic impregnation modules, so that the fibers can be fully infiltrated by the resin.

Description

technical field [0001] The invention relates to the technical field of continuous fiber prepreg production, in particular to a high-frequency vibration continuous fiber prepreg production device. Background technique [0002] Thermoplastic prepreg refers to the composition of thermoplastic resin impregnated with continuous fibers or fabrics under strictly controlled conditions to form a resin matrix and reinforcement. Among them, impregnation is also called gluing and dipping. At the same time, thermoplastic prepregs are also intermediate materials for the manufacture of thermoplastic composites. Compared with thermosetting prepregs, due to the very high viscosity of thermoplastic resins, the minimum viscosity at the general process temperature exceeds 100Pa.s, which makes the process of gluing and impregnating difficult, and continuous fibers or fabrics are not easy to be soaked. At present, the preparation of thermoplastic prepregs at home and abroad mostly adopts the mel...
