Pultruded Carbon Fibre Tube (Hollow) 8mm(OD) * 6mm(ID)* 1000mm(L)

Pultruded carbon fiber round tube(Hollow) manufactured from 100% unidirectional carbon fiber, which gives them excellent strength along their length but does make them vulnerable to crushing forces.

Pultruded tubes are ideal for scale aircraft, gliders, helicopters or any construction that requires strength, rigidity, and lightness. The Pultrusion process allows incredibly tiny diameter tubes to be produced.

Pultrusion:

Pultrusion is a method of manufacturing continuous lengths of a fiber-reinforced section by pulling continuous strands of carbon fiber through resin and a former before curing the resin all in one process.

Internal release agents are used in the pultrusion process, which migrates to the part´s surface. A pre-treatment of the adherent due to this is necessary. These have to be roughened (abrasive paper 220 grit) and cleaned very thoroughly. Epoxy resin or cyanoacrylate (superglue) is used for the bonding itself.

The straightness of pultruded CFRP tubes is due to manufacturing reasons worse than the straightness of CFRP tubes which are manufactured with the "Pullwindig"- technology. Wound carbon tubes perform best, but are also much more expensive. Smaller diameters are straighter than large diameters. Pultruded CFRP tubes are the right choice when high strength should be achieved at a low price. The tolerances in the inner and outer diameters are low, but vary depending on the diameter typically between 0.1 mm and 0.2 mm. The tolerance of the straightness to 1 meter is in any case less than 1 mm.

What carbon fiber tube you can buy from us?

LIJIN manufacturing and wholesale multiple finishes with standard modulus carbon fiber tubes offer excellent strength and stiffness, it is 1.5X stiffer than aluminum and is the most economical grade composite tube. Finishes available be twill gloss and twill matte.

How to make carbon fiber tubing?

Our carbon fiber round tube is rolled unidirectional carbon fiber fabric into a mandrel, and roll wrapped a 3k finish fabric exterior. Unidirectional carbon fiber is the structural backbone of all our tubes, the 3k fabric weave that gives carbon fiber tubes their traditional ”carbon fiber look” is only the outside layer and helps with durability. Usually, any wall thickness can be made by changing the number of layers or combining different prepreg thicknesses (usually 0.15mm- 0.25mm thick per layer).

Our round tubes typically use layups designed for optimal performance in a wide range of conditions. We use 100% pure carbon fiber materials making carbon fiber tubing in a wide variety of diameters and lengths. Common diameter includes 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm carbon fiber tube, ... 40mm carbon fiber tube, our round tube standard length is 1000mm, If you need a carbon fibre tube with other lengths or diameters, or need colored carbon fiber tube, do not hesitate to contact us, we can cut and custom carbon fiber tubes to your specified.
