Filament winding equipment frp pipe

Types of filament winding equipment FRP pipes

The filament winding equipment consists of various machines that produce FRP pipes using the filament winding process. Based on the arrangement of the axis and mandrel, the machines can wind at an angle or in an helical manner. An automatic traverse mechanism controls the movement of the yarn or wire holder, though some machines have a fixed path. Additionally, the machines can be classified based on the type of mandrel used to support the shape of the pipe. Solid mandrels are used for hollow workpieces, while collapsible or sacrifical mandrels are used for complex internal shapes. Practioners can also use rotary or non-rotary mandrels depending on the specifications of the desired pipe.

The filament winding machines can also be distinguished according to how the reinforcing fibers are combined with the resin. In low-voltage machines, the wire is directly connected to the electrical source, which has low energy requirements. High-voltage machines, on the other hand, have a higher resin power and may have different spray or transfer systems. Lastly, depending on their automation level, filament winding machines can be fully computerized, requiring minimal human input, semi-automated, or manually controlled.

Specification and maintenance of filament winding equipment FRP pipes

Specification

• Applicator width: The applicator width refers to the width of the device that holds and applies the filament (usually fiber) onto the FRP (Fiber Reinforced Plastic) pipe during the filament winding process. It can affect the coverage width of the applied filament on the pipe. Winding machines may offer custom applicator widths to accommodate different pipe diameters and filament types. The choice of applicator width depends on the specific filament winding project requirements, such as the diameter of the FRP pipe and the type of filament being used for reinforcement.
• Applicator diameter: The applicator diameter refers to the diameter of the device or platform onto which the filament is wound to create FRP pipes. It essentially acts as a mold or support for shaping the FRP pipe while the filament is wound around it. The choice of applicator diameter is crucial because it determines the final diameter of the FRP pipe being produced. Depending on the specific requirements of FRP pipe manufacturing, the applicator diameter may need to be adjusted to create pipes of different sizes and dimensions.
• Winding Angle: The winding angle indicates the orientation of the fibers that make up the reinforced material. FRP is made by winding reinforcing fibers (such as glass fiber, carbon fiber, etc.) together with a resin matrix onto a rotating mandrel in a specific angle manner. The winding angle affects the mechanical properties, strength, stiffness, and impact resistance of the final FRP product.
• Mandrel Size: The Mandrel Size refers to the shape and size of the support used to wind the fiber. The material has a certain size and shape after winding. The size of the mandrel directly determines the size and shape of the final product.

Maintenance

• Regular cleaning: Clean the equipment head, winding platform, and other parts of the filament winding to remove resin, fiber, dust, and foreign matter. Use suitable cleaning agents and tools to avoid damaging the equipment.
• Lubrication: According to the equipment manual, regularly lubricate the moving parts of the filament winding equipment, such as bearings, slides, etc., to ensure their smooth operation and reduce friction and wear.
• Check the tension control system: The filament winding machine usually possesses a tension control system to ensure proper tension during winding. Regularly check and adjust the tension control system to ensure appropriate tension.
• Maintain the electric machine: Periodically check the electrical components and circuitry of the filament winding equipment, ensuring connections are firm, free from damage, and operating correctly. Lubricate and maintain the electric drive system according to the user manual to keep it running smoothly.
• Calibration of winding parameters: Regularly calibrate winding parameters such as speed, winding angle, etc., to ensure the accuracy and stability of these parameters. This maintains the consistency and quality of the final product.
• Routine maintenance and repair: Develop periodic maintenance and repair plans for filament winding equipment, which involves routine maintenance and repair of key components and parts according to the equipment manual.
