Abstract

The invention provides wide-width continuous fiber thermoplastic resin preimpregnation equipment. The wide-width continuous fiber thermoplastic resin preimpregnation equipment comprises a fiber cone creel, a fiber dividing device is arranged at the yarn outlet end of the fiber cone creel, a mud water tank device is arranged at the yarn outlet end of the fiber dividing device, the fiber dividing device comprises a three-roller device used for generating and maintaining fiber tension, a plurality of shaking shafts are horizontally arranged at the yarn outlet end of the three-roller device, the shaking shafts do reciprocating motion in the direction perpendicular to the fiber motion direction, and the motion directions of every two adjacent shaking shafts are opposite. A digital display typetension controller and a magnetic powder brake are arranged, so that digitalization of fiber cone yarn unwinding tension detection is achieved, the tension detection precision is greatly improved, andconstant unwinding tension of all fiber cone yarn fibers is achieved; the adjustment is convenient, the precision is reliable, and the time and labor are saved; and a guarantee is provided for finally preparing the wide-spoke unidirectional cloth.

Description

technical field [0001] The invention relates to a thermoplastic prepreg machine. [0002] Specifically, it relates to a wide continuous fiber thermoplastic resin prepreg equipment and its production process. Background technique [0003] In 2008, the domestic composite material forum first introduced that thermoplastic composite material is an advanced composite material. In the field of composite materials, prepreg is a semi-finished material. Around 1998, thermosetting resin carbon fiber prepreg appeared for the first time in China. Thermosetting resin is epoxy resin. Resin-like, curing temperature 120 degrees. Most leisure products such as fishing rods and badminton rackets are made of thermosetting carbon fiber prepreg, which requires thermosetting prepreg equipment to prepare. [0004] The melting temperature of the polymer resin required for thermoplastic composites is in the range of 200-450 degrees. For example, the melting temperature of polyether ether ketone is ...
