Super Light High Stiffness CFRP Carbon Fiber Reinforced Polymer Tube

Product Specification

Super Light & High Stiffness CFRP (Carbon Fiber Reinforced Polymer) Tube

LIJIN is able to provide an extensive range of high-performance, lightweight composite tubing for use in a wide variety of industries and applications. Our assortment of composite tubes are manufactured through roll wrapping, pultrusion, or filament winding processes in the most popular composite materials such as carbon fiber, fiberglass. Available in standard and custom sizes, our lightweight, composite tubes exhibit outstanding strength, durability and rigidity. They deliver excellent tensile strength characteristics compared to conventional structural metals and are a first choice in a variety of performance applications.

Due to their unique properties, carbon fiber tubes are used in numerous applications over traditional materials such as aluminum, steel, and titanium.

• High strength and stiffness with low weight
• Excellent fatigue resistance
• Dimensional stability: Low to Zero CTE (Coefficient of Thermal Expansion)

Our Carbon Fiber Reinforced Polymer (CFRP) structural tubes have the following advantages over tubes offered by our competitors:

1. Optimized for Maximum Strength-to-Weight Ratios. We have optimized the designs of our CFRP structural tubes for maximum strength-to-weight ratios. Unlike tubes offered by our competitors, our structural tubes contain no decorative plies or coatings: every fiber and gram of our tubes contributes to structural strength. Our tubes contain mostly 0˚ (axially aligned) plies, with one 90˚ ply near the inside diameter and a second 90˚ ply near the outside diameter, to provide hoop stability.

2. Optimized for Maximum Bond Strength. Our competitors sell tubes with 90˚ plies on the Inside Diameter (ID) and on the Outside Diameter (OD); however, adhesive bonds have greatest strength when the parts have fibers axially aligned on the bonded surfaces. Our CFRP structural tubes have fibers axially aligned on the ID and the OD, to maximize bond strength.

3. No Stress Concentrations. Our competitors consolidate tubes with heat-sensitive “shrink tape.” Shrink tape leaves helical grooves around the tube ODs, which provide stress concentrations that limit the bending, tensile, and compressive strengths of our competitors’ structural tubes. On the other hand, our proprietary manufacturing process produces no stress concentrations in the hoop direction, so the structural strengths of our tubes are not limited by stress concentrations.

4. Lowest Prices in the Industry. Our proprietary manufacturing process not only produces superior CFRP structural tubes, but our proprietary manufacturing process also enables us to produce tubes at lower costs than our competitors, so we can offer CFRP structural tubes for the lowest prices in the industry.

What are carbon fiber tubes used for?

Carbon fiber tubes are used in a wide range of applications, including tactical ladders, systems, rods, and beams. Carbon fiber provides low weight, and better mechanical properties over conventional materials like aluminum, and steel.

Are carbon fiber tubes strong?

Carbon fiber tubes are used in numerous applications like tactical ladders, trusses, beams, and more. Carbon fiber is typically chosen over traditional materials such as aluminum, steel, and titanium because of the following properties: High strength and stiffness to weight.

Do carbon fiber tubes bend?

Our carbon fiber tubing is built using a thermoset epoxy resin. This means that once cured the epoxy never returns to a liquid state. If you tried to bend our tubing it would break with enough applied force but it will not bend. Carbon fiber/epoxy composite is very stiff!
