Product Specification

Highly Corrosion Resistance 100% 3K Carbon Fiber Square Tubes

Carbon fiber square tubes, also known as carbon fiber square profiles or carbon fiber box sections, are hollow structures with a square cross-section made from carbon fiber reinforced polymer (CFRP) composites.

LIJIN carbon fiber square tubes are manufactured using state-of-the-art techniques, including pultrusion as well as compression molding technique to ensure high quality and durability. In the pultrusion process of fabrication of carbon fiber tubing the continuous pulling of carbon fiber composites is mixed with resin matrix through heated forming dies to create continuous length of tubes which provides tubes with unidirectional properties.

In compression molding, on the other hand, involves multiple wraps of carbon fiber prepregs in various weave types. The result is a densely reinforced carbon composite with excellent strength and stability. Our carbon fiber square tubes are available in multiple surface textures, including twill weave and plain weave, and come in a gloss or matte finish. Due to the square shape, it has a better areal moment of inertia which gives higher bending strength. When compared to circular tubes iis t perfect for lightweight stiff applications.

Weight Difference Between 6063 Aluminium and Carbon Fibre?

The weight difference between 6063 aluminum and carbon fiber will depend on the specific dimensions and thickness of the material. However, in general, carbon fibre is significantly lighter than aluminum.

For example, a 1-meter long, 25mm diameter carbon fibre tube with a wall thickness of 1.5mm weighs around 130 grams, while a 6063 aluminum tube of the same dimensions would weigh around 340 grams. This means that the carbon fibre tube is about 60% lighter than the aluminum tube.

In general, carbon fibre has a higher strength-to-weight ratio than aluminum, which means it can withstand higher loads or stresses while remaining lightweight. This is why carbon fibre is often used in applications where weight reduction is a priority, such as aerospace, automotive, and sporting goods industries.

Is Carbon Fibre Stronger Than Steel (in terms of strength)?

Carbon fibre is a composite material made of carbon fibres and matrix material, such as epoxy resin. The carbon fibres are incredibly strong and stiff, while the matrix material provides support and protection for the fibres. Carbon fibre has a very high strength-to-weight ratio, which means it can handle high stress or load without adding significant weight. This makes it ideal for use in lightweight, high-performance applications, such as aerospace, motorsports, and sporting goods.

On the other hand, steel is a metal alloy that is known for its strength and durability. Steel has a high tensile strength, which means it can resist tension or stretching forces, and a high compressive strength, which means it can withstand compression or squeezing forces. Steel is also relatively affordable and easy to work with, which makes it a popular choice for a wide range of applications, such as construction, infrastructure, and heavy machinery.

While carbon fibre is generally stronger than steel in terms of strength-to-weight ratio, it is not as strong as steel in terms of absolute strength. Steel is stronger than carbon fibre in terms of sheer strength, which means it can withstand higher loads or forces without breaking. This is why steel is often used in applications where strength and durability are critical, such as bridges, buildings, and machinery.

Ultimately, the choice between carbon fibre and steel will depend on the specific application and requirements. Carbon fibre is ideal for applications that require high performance, lightweight, and high strength-to-weight ratio, while steel is more suitable for applications that require sheer strength and durability.
