Problems solved by technology

However, the fabric produced by 12K carbon fiber yarn on the market currently has the smallest single-layer unit area mass of 190g / m 2 , while the density of carbon fiber yarn is only 1.8g / m 3 , so this kind of fabric is relatively thick, with large deviations in mechanical properties, especially the poor covering performance, so that the quality of the subsequent parts cannot be well guaranteed, which seriously restricts the use of carbon fiber yarns in the high-end field.

Abstract

The invention relates to a fiber spreading traction device which comprises a support, a synchronous driving device, a roller fiber spreading device, a tension balance fiber spreading device and an extensible thrusting device capable of pushing the tension balance fiber spreading device to achieve opening and closing. The synchronous driving device is fixed in the middle of the support, and the roller fiber spreading device is fixed on the support and connected with the synchronous driving device through a transmission belt. The tension balance fiber spreading device is located on the downstream of the roller fiber spreading device, one end of the tension balance fiber spreading device is hinged to the support, the other end of the tension balance fiber spreading device is connected with the roller fiber spreading device through a tension spring, and the extensible thrusting device is fixed on the support and located above the tension balance fiber spreading device. The fiber spreading traction device can spread carbon fibers to be wide, thin and flat.

Description

technical field [0001] The invention relates to a fiber spreading and pulling device. Background technique [0002] Carbon fiber multi-axial warp knitted fabric preforms / LCM process parts have been successfully applied on the new generation of large aircraft Airbus A380, Boeing 787 and Airbus A400M; the rear of Airbus A380 and Boeing 787 aircraft The dome-shaped frame shell of the pressure frame is preformed with 0° / 90° warp-knitted carbon fiber fabric; A380 outer wing spar; A400M cargo door; A380 window frame is made of carbon fiber multiaxial warp-knitted fabric sewing reinforcement ribs. At present, my country has successively built a number of large-scale projects; large aircraft, large-scale offshore wind power generation, lightweight automobile tracks, etc., all require a large amount of carbon fiber multi-axial warp knitted fabrics. This product has a very broad application prospect in our country. [0003] Tests on carbon fiber fabrics have shown that the thinner t...
