The invention discloses a tow prepreg tape winding laying process suitable for winding and laying of a tow prepreg tape using carbon fiber, glass fiber, aramid fiber, ultra-high molecular polyethylene fiber and other special fiber for producing rotary parts. According to the process, a tow prepreg tape and modified fiber winding process is used to form a new winding and laying process to replace a traditional wet winding process, efficiency, workshop cleanness, product performance and quality of the winding process are greatly enhanced, performance, quality and production efficiency of various types of products(such as various types of composite cylinders and composite material pipes) prepared by the fiber winding process can be enhanced, and the zero angle laying function which cannot be achieved by a traditional winding process can be realized.

Description

technical field [0001] The invention belongs to the field of composite materials, is a new material form and process of fiber-reinforced resin composite materials, replaces the existing composite material form and winding process, and can achieve higher efficiency, better performance, lower cost and zero-angle laying composite rotary body parts. Background technique [0002] Filament winding is a traditional and classic process of composite materials, and it is also a direct process from fibers to parts. Due to the simple process route, it is a low-cost, large-scale production process. The traditional winding process is a wet process. The fiber is introduced into a liquid resin tank, and after infiltrating the resin, the excess resin is squeezed out by a squeeze roller, and then the winding is completed on the product core. The traditional wet winding has many disadvantages. The resin needs to be prepared on site, the liquid resin contaminates the equipment, needs to be cle...

AI Technical Summary

Problems solved by technology

The traditional wet winding has many disadvantages. The resin needs to be prepared on site, the liquid resin pollutes the equipment, and needs to be cleaned up every shift. The liquid resin is thrown out, so the speed of the winding machine cannot be increased, and the production efficiency is low; for relatively fragile fibers, such as carbon fibers, in the resin infiltration, hairs will accumulate, and these hairs will increase if they are not cleaned in time. There are more fuzzy fibers in the resin tank, which leads to a decline in product quality; the fibers will slide during the wet winding process, resulting in product appearance and quality problems; because it is a liquid resin, the curing process needs to rotate the part to prevent flow; due to the unevenness of the resin And, only part of the mechanical properties of the fiber can be exerted, the mechanical properties of the workpiece are large, and the safety factor taken in the design is high, resulting in high material costs; the winding process is to wind the fiber to the core through the rotating motion of the core. The adhesion between the fiber with liquid resin and the core or the previous winding layer is not enough. Therefore, the traditional winding process cannot realize the fiber alignment in the direction parallel to the axis of the core (or at zero angle), and there cannot be parallel fibers in the zero direction. Reinforcement, which limits the scope of application of the fiber winding process, all these problems require a new composite material form and an improved tow prepreg tape winding and laying process to solve
