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.
NitPro 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 makes it perfect for lightweight stiff applications.

Our pultruded carbon fiber tubes are made using the advanced "Pultrusion" process, which involves a continuous process used to manufacture fiber-reinforced polymer composite profiles with a constant cross-section through heated forming dies.
We provide composite having composition material typically consisting of a thermoset or thermoplastic polymer, reinforced with carbon fiber, aramid fibers or different combinations.
This highly automated process creates continuous length of tubes with constant cross-sections in the shape of the die. The result is a densely reinforced carbon composite that provides exceptional strength and durability.
These tubes are ideal for a variety of applications that require high strength and low weight, including aerospace, engineering and construction. With their uniform diameter and smooth surface finish, pultruded carbon fiber tubes offer reliable performance and easy integration into your projects.

• Exceptionally rigid
• High dimensional stability and UV resistant
• High corrosion resistance
• High thermal conductivity in some forms
• Very low thermal expansion (approx. 8 times lower than steel, 11 lower than aluminium)

• We specialize in Carbon Fiber Pultruded Carbon Fiber tubes and different profiles.
• Our products are available in varying dimensions and can also be customized as per requirements.
• We produce hollow tubes starting from 4 mm to 25 mm in diameter, in desired wall thickness.

Carbon fiber rods are solid cylindrical structures made from carbon fiber reinforced polymer (CFRP) composites. Similar to carbon fiber tubes, they offer exceptional strength, stiffness and lightweight. However, unlike tubes, the rods do not have a hollow center and are used for different purposes.

The manufacturing process for carbon fiber rods involves impregnating carbon fiber bundles with resin and then subjecting them to heat and pressure to cure the composite. The resulting solid carbon fiber rods exhibit excellent mechanical properties and can be machined or cut to the desired length.

The pultruded carbon fiber rods can vary in diameter, length and the number of carbon fiber bundles used, allowing for customization based on specific requirements and applications.

Overall, carbon fiber rods offer a combination of strength, lightweight and durability, making them a popular choice for industries where performance and weight reduction are crucial factors. Get customized sizes and lengths when selecting them for a particular application.

NitPro Composites CARBOTEX (BD) is a bidirectional and CARBOTEX (UD) is a Unidirectional woven carbon fiber fabric with incredible low-weight to-high-strength-ratio, designed for installation using the dry or wet application process. These fabrics are applied to the surfaces of existing structural members in buildings, bridges, beams, columns, or slabs, these fabrics offer a reliable solution for enhancing structural stability and durability while enhancing their load-bearing capacity and structural integrity. The bidirectional fabric provides strength in both directions, while the unidirectional fabric is ideal for reinforcing specific areas that require increased tensile strength.

Carbon fiber composite sheets are produced by compression molding method as well as vacuum infusion using carbon fiber fabric with epoxy resin, carbon fiber prepreg.

In the process of compression molding, carbon fiber prepreg placed into mold, now the prepreg gets heated under pressure into mold with large hydraulic presses. Sheet gets cured as per curing cycle in varying dimensions.

The Vacuum Infusion method uses vacuum pressure to inject resin into a laminate. Dry carbon fiber layers are laid into the mold and the vacuum is applied before resin is infused. Once a complete vacuum is achieved, resin is literally sucked into the carbon fiber layers.

We deliver uncompromising quality and craftsmanship. Our carbon fiber sheets are consistent in quality with a superior glossy surface finish. Sheets are available in various thicknesses. Depending on the application, the sheet stiffness can be engineered using different carbon fiber layups.

Carbon fiber composite sheets can be cut into smaller sizes or custom parts with our carbon fiber machining services. We support many different industries that value strength and light weight.

CNC service is available, according to customers design, we do customized machining as per 3D files or drawing (.Igs, .stp Format). Carbon fiber tubes, sheets and other carbon fiber products are used to make customized Carbon Fiber Parts for RC Helicopter, RC cars, UAV Drone frame etc.

Prepreg carbon fiber tubes are constructed using multiple layups of multi-directional and/or uni-directional prepregs. NitPro Composites utilize carbon fiber prepregs along with epoxy matrix in prepreg tubes.
The carbon fiber tubes are best for applications that require high bending stiffness and low weight such as drones and UAV, automobile parts, telescopic poles, fishing rods, etc.
We provide 3k to 12k carbon fiber tubes in different finishes like cello-wrapped gloss, smooth grinded gloss, smooth grounded matte finish having twill weave, plain weave and unidirectional weave pattern. We also provide customized finishes according to client requirements.
Prepreg tubes results in maximum consistency across the thickness of tubes. The process also affords more customization in terms of fiber orientation which gives better mechanical properties e.g. compression, bending, shear, etc. Our Prepreg carbon fiber manufacturing process is primarily used for producing small to medium-diameter tubes from 6.0mm through 105mm diameter and length up to 2 meters long.
