Carbon Square Tubes - CFRP Pipes - Directly from the Manufacturer

CARBON SQUARE TUBES, CARBON SQUARE TUBES

Carbon square tubes carbon square tubes or carbon rectangular tubes are particularly suitable for many applications. These CFRP pipes are very interesting not only because of the visually appealing design but also because of their easy adaptability with existing systems. The excellent material properties are convincing in many areas of application and thus represent the decisive advantage.

We offer carbon square tubes or carbon square tubes in various dimensions directly from stock. The various square CFRP carbon tubes not only differ in terms of their overall dimensions but are also available with different corner radii and in reinforced versions. Of course, we also offer our cutting service or complex processing for all tubes in these categories square tubes / square tubes. This enables you to realize your lightweight constructions quickly and professionally.

CFRP SQUARE PIPES WRAPPED DIRECTLY FROM THE MANUFACTURER

The same applies to these special carbon tubes -> carbon square profiles, as to all our carbon semi-finished products, they are light, very resilient, and durable. They offer optimal performance for all areas of application with the highest demands. The prepreg carbon fiber winding technology specially developed by us is also used for these tubes. The inner and outer surfaces of these carbon fiber tubes are very dimensionally stable, so time-consuming post-processing to adapt them to their systems may not be necessary.

As with our round tubes, we also have the option of adapting the fiber directions to your individual needs with the carbon square tubes / square tubes via the fabric / non-crimp fabric. This allows us to adapt the CFRP pipes to a wide variety of load cases so that they have maximum tensile and compressive strength and torsional stability with minimum deflection. There is also the option of using different fiber types so that the carbon square tubes/square tubes can also be adapted for applications with special requirements, for example in terms of corrosion protection, heat resistance or electrical conductivity.

CONSTRUCTION OF OUR CARBON ROUND TUBES, CARBON SQUARE TUBES AND CARBON SQUARE TUBES

HT, UHT and IM carbon fibers are used for our square CFRP carbon fiber tubes as well as for our round carbon tubes. These are either impregnated directly with an epoxy resin matrix or previously processed into fabrics and fabrics and then impregnated. The resulting so-called prepregs are then wound using our specially developed molds and then hardened in the tempering oven. This is the core process of our production of carbon round tubes and square tubes. The specific flexural strength, compressive strength, tensile strength and torsional stability (per unit of mass) are therefore significantly higher than with corresponding metal products.

The weight saved as a result and the low mass inertia are the main advantages of our CFRP square/round tubes. At the same time, the semi-finished products get their particularly appealing fabric structure surface made of carbon, which is often preferred for optical requirements. Basically, we can also offer the surface ground, wrapped or high-gloss, painted. Since our carbon profiles are generally not susceptible to corrosion, they do not have to be additionally painted. The areas of application of all our CFRP products and semi-finished products are very extensive and cross-market.

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.

Whether used in the construction of aircraft components, automotive parts, sporting equipment, or other engineering applications, Carbon Fiber Composite Tubes are valued for their exceptional mechanical properties and versatility. When considering such tubes for a specific application, it's crucial to communicate with manufacturers to ensure that the tube's specifications meet the project's requirements.
