In this article, we will explore the definition, background, and importance and application prospects of filament-wound construction in various fields.
Filament Winding
Definition and background of filament wound construction
Filament winding construction is a manufacturing technology that combines fiber materials, such as fiberglass, carbon fiber, etc., with resin or other adhesives, and then wraps them around a mold or structural surface to form the desired shape and structure. This method typically uses automated machines or robots to control the fiber winding process to ensure precise and efficient manufacturing.
Filament winding construction technology originated in the aerospace field in the 1960s and was initially used to manufacture structural components of aircraft such as aircraft and missiles. With the continuous development of material science and manufacturing technology, fiber-wound construction is gradually used in automobiles, ships, construction, sports equipment and other fields. Its unique manufacturing method makes complex structures and lightweight designs possible, revolutionizing the field of engineering.
The importance and application areas of filament winding technology
Fiber winding technology plays an important role and is widely used in the engineering field. First, it can improve the strength and stiffness of the manufacturing structure, making the product more durable and safe. By selecting fibers of different types and directions, the mechanical properties of manufactured parts can be adjusted to meet different engineering needs.
Secondly, filament winding technology enables the manufacturing of complex shapes and designs. Compared with traditional manufacturing methods, it can more flexibly adjust the shape and size of the structure to meet the designer’s requirements for product appearance and functionality. This provides the possibility for innovative design and customized production, promoting the development of the engineering field.
Fiber winding technology has a wide range of applications in various fields. In the aerospace sector, it is used to manufacture aircraft fuselages, engine components and structural parts for spacecraft. In the automotive industry, it can make lightweight bodies and frames, improving fuel efficiency and performance of cars. In the construction field, it can manufacture long-span structures and complex-shaped buildings, enhancing the building’s earthquake and wind resistance. In addition, filament winding technology is also used in fields such as shipbuilding, sports equipment, and wind power generation, providing innovative solutions for various engineering projects.
Fiber Winding Process
The existing fiber winding processes are divided into core mold fiber winding, coreless fiber winding and space fiber winding.
Core Mold Filament Winding
Filament Winding (FW) can be divided into 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.
Coreless Filament Winding
Coreless Filament Winding (CFW) was first jointly developed in 2012 by the Institute for Computational Design (ICD) and the Institute for Building Structures and Structural Design (ITKE) at the University of Stuttgart, combining engineering methods and computer design. This novel robotic filament winding technology is a construction method that does not require mandrels and typically uses custom steel frames (or scaffolding) as supports, with anchor points placed on these steel frames (or scaffolding) according to the design requirements of the structure. .
During the construction process, 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 with the robot end effector at the two anchor points. Move back and forth and span freely, and form winding nodes at the anchor points; after repeatedly stacking and laying fiber layers layer by layer, a structure with a multi-layer fiber shell is finally formed; the frame is removed after the impregnated fibers solidify (or scaffolding) to complete the manufacturing of fiber wound components.
Space Fiber Winding
Coreless fiber winding is based on winding fibers around the anchor points of a prefabricated frame, using the anchor points as winding nodes, while Spatial Filament Winding (SFW) is based on coreless fiber winding and adds fibers in the Entanglement in space. Space fiber winding wraps one fiber around another fiber, so that the entanglement between fibers forms nodes.
Coreless fiber winding realizes the construction of components through layered fiber winding, but the interaction of each fiber is limited to the surface contact between each fiber. Space fiber winding expands the concept of winding nodes. By winding each fiber to create winding nodes with multi-fiber interaction, it further reduces the dependence on the frame, so that large-span components with multiple spatial winding points can be created.
