As an important advanced manufacturing technology, fiber winding technology is developing rapidly and is widely used in various fields. It uses high-strength fiber materials and winds the fibers on the surface of the workpiece in a specific way through a precisely controlled winding process, thereby giving the workpiece excellent mechanical properties and durability. The emergence of this technology not only promotes technological progress in the manufacturing industry, but also brings new solutions to all walks of life.
In this article, we will discuss the background and significance of filament winding technology, as well as an in-depth analysis of its importance in technological breakthroughs and cutting-edge applications.
Fiber winding technology is an advanced manufacturing technology that uses high-strength fiber materials to wrap fibers on the surface of workpieces in a specific manner through a precisely controlled process. Its basic principles cover the filament winding process, material selection and characteristics of filament winding, and equipment and process control of filament winding.
The fiber winding process is an advanced manufacturing technology that mainly winds fiber materials on the surface of the workpiece in a specific way, and then impregnates and solidifies them to form a composite structure. According to the different implementation methods of the process and the characteristics of fiber winding, the fiber winding process can be divided into different types, including core mold fiber winding, coreless fiber winding and space fiber winding.
Core die fiber winding is a traditional form of fiber winding process, which mainly includes two types: traditional fiber winding and robotic fiber winding. In the traditional fiber winding process, after the fiber bundle passes through the resin bathtub, the speed of the conveyor and the rotation speed of the mandrel are controlled to pull the impregnated fiber bundle so that it is wound around the mandrel at different angles. The fibers solidify under appropriate time and temperature conditions to form a filament-wound product. Robot fiber winding technology is based on traditional fiber winding technology, using industrial robots to complete fiber winding, and using multi-degree-of-freedom mechanical arms to rotate mandrels or pay-off devices for fiber winding, thereby achieving automation and precision. Production.
Coreless fiber winding is a new type of fiber winding technology that does not require a core mold to support fiber winding. The technology was first developed in 2012 by the University of Stuttgart’s Institute for Computational Design (ICD) and the Institute for Building Structures and Structural Design (ITKE). In the coreless fiber winding process, custom-made steel frames or scaffolding are usually used as supports, and anchor points are arranged on these steel frames or scaffolding according to the design requirements of the structure. The robot end effector pulls the resin-impregnated fiber filaments, and then continuously performs fiber winding actions around the frame according to the established fiber winding grammar and robot motion planning path. The fiber material moves back and forth and freely spans between the two anchor points with the robot end effector, and forms a winding node at the anchor point. After impregnation and curing, the final structure is formed with a multi-layer fiber shell.
Space fiber winding is developed on the basis of coreless fiber winding. By winding one fiber on another fiber, the entanglement between fibers forms nodes. This interaction between fibers expands the spatial dimensions of fiber winding, allowing components to have more complex geometries and structures. The space fiber winding process requires fibers to move freely in space during the weaving process, so multiple systems are required to work together and be built. Typically, this technology mainly consists of industrial robots and movable gantry, which is mounted with a rigid frame with attached anchor points. The space fiber winding process can create various geometric shapes to form multiple winding nodes within the same frame, and introduces a multi-step solidification process to iteratively manufacture continuous large-scale space frame structures.
Fiber materials usually include carbon fiber, glass fiber, aramid fiber, etc. Each fiber material has different mechanical properties and chemical properties. For example, carbon fiber has excellent strength and stiffness and is suitable for applications requiring high performance; glass fiber has good corrosion resistance and cost-effectiveness and is suitable for general engineering applications. When selecting fiber materials, factors such as the use environment, performance requirements, and cost of the workpiece need to be comprehensively considered.
It also plays a vital role in the quality and performance of the final product. Fiber winding equipment usually includes winding machines, pretreatment equipment, impregnation equipment, curing equipment, etc. These equipment need to have precise control systems to ensure that parameters such as fiber winding angle, tension, speed, etc. can be accurately controlled to ensure the stability and consistency of the process. In addition, process control also includes the optimization of process parameters, quality inspection and control, etc. to ensure that the final product can meet the design requirements and performance standards.
With the continuous advancement of science and technology and the changing market demand, fiber winding technology is also constantly innovating and making breakthroughs, providing new possibilities and solutions for applications in various fields.
