Filament winding application
Filament winding has a long history of producing axisymmetric shapes for various applications, including drive shafts, pipes/tubes, pressure vessels, tanks, rods, masts, missile cases, rocket motor cases, and aircraft fuselages. With the rapid advances in CNC and automation in filament winding equipment since the 1990s, the application of filament winding has expanded to include non-axisymmetric geometries. The section below provides a brief overview of current filament-wound composite structures in the industry.
Filament Winding: From Rockets to Racecars
Filament winding has been a key player in the aerospace industry for decades, playing a vital role in the design and manufacture of rocket engines, fuel tanks, and structural components. The high-strength-to-weight ratio of filament-wound composite materials makes them ideal for use in the harsh and demanding conditions of space travel.
One of the most famous examples of filament winding in the aerospace industry is the Space Shuttle's main fuel tank. This massive tank, which weighed nearly 140,000 pounds, was made up of a composite material that was filament wound around a mandrel. The intricate design of the tank was critical to the success of the Space Shuttle program, as it provided the necessary strength and lightness to withstand the rigors of space travel.
From the skies to the racetrack, filament winding is also being used to create high-performance sports equipment. The strength and durability of filament-wound composites make them ideal for use in car racing components, such as drive shafts and suspension components. In addition, the customizability of filament winding allows manufacturers to create unique shapes and designs that are optimized for maximum performance.
Filament Winding in the Marine Industry
Filament winding has also made a splash in the marine industry, where it is being used to create a range of products from boat hulls to mooring poles. The strength and durability of filament-wound composites make them ideal for use in harsh marine environments, where corrosion and abrasion are common challenges.
