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

Embodiment Construction

[0014] Such as figure 1 Firstly, according to different composite material matrices and their applications, reasonably prepare the matrix glue, put it into the glue groove (1-5) on the path where the fiber passes, and place the glue groove behind the tension sensor. The multi-filament fiber bobbin (1-3) is fixed on the rotating movable support, and the bobbin is fixed by apron friction. The tension of the multi-filament yarn is adjusted by the coaxial tension tension adjustment method, and the servo motor is used to adjust the tension. Drive the coaxial adjustment of the worm gear and worm, and the servo motor drives the connecting rod (1-2) through the worm gear reducer to synchronously move the friction brake mechanisms of the three bobbins at the same time, so as to achieve the effect of simultaneously adjusting the tension. The fiber tow passes through three tension rollers (1-4) and dipped in the glue tank. The tension sensor is placed before the glue tank, which not only...

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. Among them, the composite material lay-up technology is one of the fastest-growing and most effective automatic molding manufacturing technologies in recent years. 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 ...
