Multi-tow fiber preimpregnation laying device

Abstract

The invention discloses a multi-tow fiber preimpregnation laying device which comprises a grid, a multi-tow yarn drum mounting part, a tension adjusting part, a glue preimpregnation part, a glue content control part, a synchronous moving part and a laying part. The prepared base glue liquor is stored in a glue slot, the multi-tow yarn drum part is fixed on a rotary movable support; multi-tow fibers are arranged in order through the grid and then pass through a three-roll tension unit; a tension sensor is used for measuring and controlling the fiber laying tension; the multi-tow fibers are then impregnated with glue through the glue slot; extra glue is squeezed out through a glue squeezing roller; the multi-tow fiber impregnated with glue are arranged through the grid to form broad-width preimpregnation materials; and finally, the broad-width preimpregnation materials are laid through a laying head to form composite structural members. The multi-tow preimpregnation laying device has the advantages that the preimpregnation and the laying of the fibers are integrated; the laying efficiency is improved; fiber tension is uniform; the laying accuracy is high; and the glue content is controlled within 2 percent.

Description

technical field [0001] The invention relates to a multi-tow fiber prepreg laying equipment. In particular, glass fiber and carbon fiber prepreg lay-up methods and equipment for the manufacture of composite components. Background technique [0002] In recent years, various low-cost manufacturing technologies for composite materials have emerged, such as infiltration molding technology, low-temperature and low-pressure curing technology, electron beam curing technology, new winding technology, and composite fiber lay-up technology.

It has shown extremely outstanding advantages and great potential in reducing manufacturing costs and improving composite material performance. Composite lay-up forming technology is mainly used in aerospace components. Composite material layup is formed by the layup robot according to ...

AI Technical Summary

Problems solved by technology

At the same time, the in-situ instantaneous layered radiation curing is used to eliminate the influence of the tension in the fiber layup on the shape of the product, and the thermal deformation caused by the curing treatment in the autoclave is large, and cracks are easy to occur. The size of the component is limited by the volume of the autoclave. Problems and defects of high production cost and long production cycle

The equipment uses industrial robots as the main body of manufacturing, which improves the lack of flexibility of today's laying equipment to manufacture more complex profiles and its complex structure.

At present, there is no report on a multi-tow fiber prepreg laying equipment
