Pultruded Carbon Fiber or Fiber Glass Tubes

For size, shape, specification, please email to info@djtcarbon.com for further information, DJT CARBON make custom carbon fiber tubes for you.

The Low Cost Composite Manufacturing Process Pultrusion is a method of manufacturing continuous fiber reinforced composites profiles. The manufacturing process is similar to extrusion, where molten plastic or metal is pushed through a die. However, with pultrusion, the material is "pulled" through a die. (Hence the name, pul-trusion).

Pultruded Carbon Fiber and Fiber Glass Tubes
These Carbon fiber tubes are manufactured in a pultrusion process. Pultruded shapes have very straight fibers cured at high temperature resulting in high fiber to resin ratios and very stiff parts. DJT carbon tubes contain no fillers - ONLY continuous fibers. Most diameters are available up to 6M long. Dimensional tolerances are +/- 0.05mm and weight tolerances +/- 2-5%.
Compared to other materials and processes, DJT carbon fiber tubes are twice as stiff as aluminum of the same dimensions. DJT carbon tubes are 350% stronger in tension and 550% stronger in compression than the traditional wet lay-up with carbon fiber tow and room temperature resin systems.

This is the low cost composite manufacturing process, we mainly use two different process in making composite tubes: Pultrusion Process and Filament Winding.
In the following cases, it would be suitable for you to choose Pultruded Tube

Very Small to Medium Diameters

Unidirectional Fibre Alignment

Excellent Longitudinal Strength

Poor Crush Strength

Poor Twist Strength

Generally Cheaper

Common products manufactured with the pultrusion process include:
Window Lineals
Flat Sheets
Ballistic Panels
Fiberglass Tubing
Tool Handels
Archery Arrows
