Constant-temperature impregnation device for composite fiber winding

Abstract

The invention provides a constant-temperature impregnation device for composite fiber winding. The constant-temperature impregnation device for composite fiber winding is used for impregnating glass fiber and carbon fiber in the winding process and balancing fluctuation of the tension value during winding reversing and can be placed on a fiber winding tension control system to cooperate with a fiber winding mainframe to together complete processing of winding products. The constant-temperature impregnation device can be transversely and longitudinally moved according to the actual size of winding parts. The constant-temperature impregnation device is composed of a U-shaped impregnation tank, a constant-temperature device, a low-friction guide roll set, a fiber guiding device, a tension balancing device, an impregnation roll, an adjustable scraping knife and other components. Through the constant-temperature impregnation device for composite fiber winding, the technical problems that fiber is impregnated insufficiently and unevenly and fluffs due to dry friction, the constant-temperature effect of an adhesive solution is poor, the fiber is impregnated unevenly due to fluctuation ofthe fiber tension value and the quality of the winding products is affected through the existing fiber wet winding impregnation technology can be solved.

Description

technical field [0001] The invention relates to a constant temperature dipping device for fiber winding of composite materials, in particular, it can be used to realize the dipping of glass fiber and carbon fiber in the winding process and the balance of the fluctuation of tension value when the fiber winding reverses direction. Background technique [0002] Filament winding process refers to the process of winding continuous fibers soaked in resin glue on the mandrel according to certain rules, and then curing and demoulding to form composite products. It is mainly divided into dry winding, wet winding and semi-dry winding. . The wet winding involved in the present invention is a molding process in which the roving is directly wound onto the mandrel after being dipped in glue. In the previous dipping process, this process requires the fiber to be fully dipped and the amount of dipping to be uniform and controllable. Regarding fiber wet winding dipping technology, the curr...
