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.
