Carbon Fibre Pultruded Tube – 3 mm × 1.5 mm × 1000 mm

Pultruded Carbon Fibre Tube for Axial Load Applications

The Carbon Fibre Pultruded Tube 3 mm × 1.5 mm × 1000 mm provides extremely high stiffness relative to weight for precision applications that rely on straight-line load paths. The pultrusion process aligns all carbon fibres along the tube axis. As a result, the tube delivers excellent performance in tension and compression while maintaining consistent dimensions over its full length.

With a 3 mm outer diameter and 1.5 mm inner diameter, this tube suits compact, weight-critical assemblies where accuracy, repeatability, and minimal mass matter.

Performance Characteristics

Because the fibres run continuously in the 0° direction, this pultruded tube performs best under axial loading. Therefore, it suits:

• Tension and compression members

• Ultra-light structural supports

• Precision-aligned components

However, this construction does not handle torsional or side loads effectively. For twisting or multi-directional forces, designers should choose a roll-wrapped tube instead.

Processing & Bonding

This 3 mm × 1.5 mm pultruded tube cuts cleanly using fine-tooth saws, rotary tools, or CNC machining. Because the epoxy matrix supports strong adhesion, builders achieve reliable bonds using epoxy adhesives and laminating resins. Consequently, the tube integrates easily into bonded joints, fixtures, and composite assemblies.

After cutting or drilling, sealing exposed fibres improves durability and long-term performance.

Typical Applications

Because of its axial stiffness and extremely low weight, this tube is commonly used in:

• Drone and UAV internal structures (non-motor components)

• Aerospace and light aviation assemblies

• Wind energy sensors and instrumentation mounts

• Marine and boating systems with straight-line load paths

• Robotics and automation linkages

• Precision industrial and laboratory fixtures

These industries value pultruded tubing for predictable behaviour and repeatable performance at very small diameters.

Technical Specifications

The unidirectional fibre layout maximises axial strength while keeping weight to an absolute minimum.

Why Choose Enhanced Composites

Enhanced Composites supplies precision pultruded carbon fibre tubing for engineers and builders who require tight tolerances, consistent stiffness, and reliable mechanical behaviour. In addition, each tube undergoes dimensional and visual inspection before dispatch. Because of this focus on quality, every tube performs exactly as expected in demanding technical applications.

FAQs

Is this tube suitable for torsional loading?
No. Pultruded tubes optimise axial loads and do not perform well under torsion. Roll-wrapped tubes should be used instead.

Can this tube be bonded into composite assemblies?
Yes. Builders can bond the tube using epoxy adhesives and laminating resins after proper surface preparation.
