Problems solved by technology

Although the above patents disclose related devices for producing prepregs, there is no specific description of the yarn spreading equipment
Moreover, most of the equipment is only suitable for the production of prepregs with a single fixed size and fixed fiber arrangement. Changing the fiber arrangement often requires re-threading, which cannot be directly carried out in production.

Embodiment 2

[0033] A yarn spreading device, comprising a creel, a yarn arrangement device, a static elimination device, a yarn arrangement bar and a traction roller arranged in sequence. The interlayer provided on the creel body is 1 layer, on which 100 spindles are installed, the fiber rolls fixed on the spindles, the tooth mouth yarn discharge plate a located in front of each layer of spindles, and the tooth mouth yarn discharge plate a It is an aluminum plate with evenly arranged yarn through holes.

[0034] The said yarn arranging device has one layer, including a yarn arranging frame body, a tooth mouth yarn arranging plate b, a fixing screw for the tooth mouth yarn arranging plate b, and a scale fixed on the frame body. The tooth nozzle yarn-discharging plate b is an aluminum plate with uniform through holes, its position can move left and right in the slot, and it is measured by a scale fixed on the yarn-discharging frame body, and fixed by fixing screws. The yarn drawn out from t...

Embodiment 3

[0037] A yarn spreading device, comprising a creel, a yarn arrangement device, a static elimination device, a yarn arrangement bar and a traction roller arranged in sequence. There are 10 layers of compartments arranged on the creel frame body, and one spindle is installed on each layer, and the tooth nozzle yarn-discharging plate a in front of each layer of spindles is an aluminum-chromium alloy plate with uniform yarn-discharging through holes.

Abstract

The invention relates to a continuous fiber spreading equipment for prepreg production and its use method. The equipment includes a creel, a yarn arrangement device, a static elimination device, a yarn arrangement bar and a traction roller arranged in sequence. Compared with the prior art, the invention has the advantages of being able to spread the yarn evenly, being suitable for use in a production line for producing continuous fiber prepregs, and the like.

Description

technical field [0001] The invention relates to a production equipment and application of a prepreg, in particular to a device capable of uniform yarn spreading used in the production of a continuous fiber prepreg and a method for preparing a prepreg using the device. Background technique [0002] Continuous fiber reinforced prepreg has excellent mechanical properties, and its low density and recyclability conform to the concept of energy saving and environmental protection, and has been developed rapidly in recent years. The material can be processed into high-strength plates by molding, and the design and manufacture of structural parts can be realized through different molds. [0003] The good mechanical properties of prepreg are determined by the impregnation of matrix resin and reinforcing fiber. In its production process: yarn spreading, impregnation, shaping and winding, the quality of yarn spreading directly affects the quality of prepreg. performance parameters. T...
