Fiber spreading device for woven carbon fiber one-way cloth

Abstract

The invention relates to the technical field of fiber spreading in fiber weaving production, in particular to a fiber spreading device for woven carbon fiber one-way cloth. The device comprises a pre-heating fiber spreading roller, a prismatic fiber spreading roller and a traction roller; the surface part of the pre-heating fiber spreading roller winds passing yarn and heats the yarn; the prismatic fiber spreading roller is rotatably arranged, the surface part of the prismatic fiber spreading roller winds passing yarn, and the rotary surface of the prismatic fiber spreading roller is set to have elevation difference to change the distance between the yarn passing through the surface of the prismatic fiber spreading roller and a rotary axis center of the prismatic fiber spreading roller; the traction roller is a driving roller, and provides traction power for the yarn passing through the pre-heating fiber spreading roller and the prismatic fiber spreading roller. According to the fiberspreading device, by arranging the fiber spreading roller to be of a prismatic structure, vibration motors in the prior art are replaced, when the prismatic fiber spreading roller rotates, the position of the yarn on the prismatic fiber spreading roller is changed periodically, by means of the principle, the yarn also vibrates at a certain frequency, the vibration only occurs to the yarn, and cannot influence the whole device, and meanwhile, the effects of widening, thinning and flattening the yarn during spreading are better.

Description

technical field [0001] The invention relates to the technical field of fiber spreading in fiber weaving production, in particular to a fiber spreading device for woven carbon fiber unidirectional cloth. Background technique [0002] In recent years, carbon fiber, as a high-tech material, has been widely used at home and abroad. In industrial applications, unidirectional prepreg or woven fabric is usually formed by unidirectional prepreg or weaving for the next step. In the process of making unidirectional woven fabrics, in order to obtain unidirectional woven fabrics with thin thickness, low weight and good performance, it is necessary to fully expand the carbon fiber tow to a certain width. [0003] There are many ways to expand carbon fiber. Commonly used expansion methods include roller extrusion method, liquid ultrasonic method, vertical air flow method, etc., but in general, the better the yarn spreading effect, the greater the damage to the fiber.
