Carbon Fiber Tubes
Engineering and sourcing guide to carbon fiber tubes: pultruded, roll-wrapped and filament wound constructions, sizing, stiffness and weight trade-offs.
14 articles
Tubes are the most widely used structural form of carbon fiber composite, and the construction method decides almost everything about performance: a pultruded tube maximises axial stiffness per cost, a roll-wrapped tube gives clean cosmetic surfaces, and a filament wound tube handles hoop and torsional loads. This collection covers how each is made, when to choose which, and how to specify a tube that actually matches your load case.
Pultruded Continuous Spars for Automated Blades: Design-for-Manufacturing and Detachable Modular Joints
Blade architecture has been remarkably stable for two decades. A blade is a laminated shell, a spar cap that carries the bending load, and a web or shear web system that keeps the cap in position; the spar cap is almost always built at the blade factory, either by stacking pultruded pla

Wind turbine blades have grown to lengths that were unthinkable two decades ago, and that growth has pushed blade designers toward stiffer, lighter structural members. The spar cap — the long beam that runs from root to tip along each side of the blade and carries the majority of bendin

India is joining the global wind-grade carbon fiber supply chain from a position most observers did not anticipate: not as a raw fiber importer or a blade maker's secondary source, but as a supplier of pultruded carbon planks to one of the world's largest wind turbine manufacturers. Kin

Filament winding is the dominant manufacturing process for Type IV hydrogen pressure vessels, the composite overwrapped tanks used in fuel cell vehicles, hydrogen refueling stations and transport trailers. Demand is expanding rapidly: the global Type IV hydrogen vessel market was valued

Sports and leisure applications account for roughly 28% of carbon fiber demand in China, and the bicycle frame is the single largest product within that segment. Yet the frames that roll out of premium brands are made by very different processes under the surface. The two dominant route

Type IV cylinders — fully composite pressure vessels with a polymer liner and a carbon fiber overwrap — are the storage technology of choice for hydrogen fuel-cell trucks, buses, and station cascades. Their defining advantage is weight: a Type IV vessel can be 40 to 70 percent lighter t

Solar panel frames have been aluminum for as long as modules have been mass produced. Extruded 6063 alloy rails are cheap, proven, and recyclable, and they do the job on millions of panels worldwide. But the job is changing. Modules are getting larger — 2.5 m by 1.3 m panels are now sta

Automated composite manufacturing — automated fiber placement (AFP), filament winding, and braiding — runs on a narrow family of precursor materials. For decades the default was standard unidirectional prepreg slit into tape, or dry tow used with a separate resin injection step. Carbon

As wind turbine blades extend beyond 100 meters for offshore 15 MW+ platforms, spar cap design and manufacturing have become the critical bottleneck in blade production. The spar cap — the primary load-bearing structure running along the blade's length — must withstand extreme tensile and.
