TECHNICAL FIELD
[0001] The utility model belongs to one -way pre -impregnated tape technical field relates to a kind of impregnation equipment of composite one -way pre -impregnated tape. BACKGROUND
[0002] The existing one-way pre-impregnated tape has the disadvantages of low dehydration efficiency, uneven dehydration and easy to produce bubbles and pores in the pre-impregnation dehydration aspect. The causes of these shortcomings lie in the material structure and manufacturing process of the pre-impregnated tape. Since the pre-impregnated tape is usually composed of resin and fiber, the resin may not be able to completely fill the gap between the fibers during the impregnation process, making it difficult to remove water during the curing process. In addition, the pre-impregnated tape may be unevenly distributed due to uneven pressure, improper temperature control and other factors during the manufacturing process, further affecting the dehydration effect.
[0003] The conventional methods include increasing the pressing pressure of the pre-impregnated tape, prolonging the curing time of the pre-impregnated tape and using vacuum-assisted curing technology. Increasing the pressing pressure can promote the flow of resin, fill the gap between the fibers, and thus improve the dehydration efficiency. Prolonging the curing time gives more time for water to be removed by diffusion. Vacuum-assisted curing technology helps to remove bubbles and excess water by reducing pressure, improving dehydration uniformity, however, these methods also have disadvantages. Prolonging the curing time will reduce production efficiency and increase production cost. Although vacuum-assisted curing has significant effect, it requires additional equipment investment and maintenance cost, and may be difficult to implement in large-scale production, therefore, there is an urgent need for an impregnation equipment for composite one-way pre-impregnated tape to solve the above problems.
