Carbon Fibre Roll Wrap Tube – 7 mm × 3 mm × 1000 mm

Precision Roll-Wrapped Carbon Fibre Tube – 7 mm × 3 mm

The Carbon Fibre Roll Wrap Tube – 7 mm × 3 mm × 1000 mm delivers an excellent balance of stiffness, low weight, and multi-directional strength for compact structural builds. Unlike pultruded tubes, the roll-wrapped construction layers fibres in multiple orientations. As a result, the tube handles torsion, bending, and crushing far more effectively while still keeping mass to a minimum.

With a 7 mm outer diameter and 3 mm inner diameter, this tube suits applications where space stays tight yet strength and stability still matter. At the same time, the controlled laminate structure keeps performance predictable under mixed loading.

Performance Characteristics

Because the fibres wrap around the tube at different angles, this roll-wrapped design performs well in both axial and torsional load paths. Therefore, it suits:

• Twisting and bending loads

• Dynamic structural members

• Compact high-stress components

However, while it resists torsion very well, it does not match pultruded tubes for pure straight-line compression or tension. For pure push–pull loads, a pultruded tube remains the better choice.

How to Cut and Bond

This 7 mm × 3 mm roll-wrapped tube cuts cleanly with a fine-tooth saw, diamond wheel, or rotary cutting tool. Because the laminate uses an epoxy resin system, it bonds extremely well with epoxy adhesives and laminating resins. As a result, builders integrate it easily into composite assemblies, fixtures, and bonded joints.

After cutting, sealing the ends helps protect the exposed fibres and improves long-term durability.

Typical Uses

• Lightweight UAV and drone structural arms

• Robotics and automation linkages

• Compact structural bracing

• Sporting equipment components

• Precision composite frames

• Engineering builds requiring torsional strength in a small diameter

Technical Specifications

The multi-directional fibre layout allows the tube to resist twist and side load while remaining light and rigid.

Why Choose Enhanced Composites

Enhanced Composites supplies precision roll-wrapped carbon fibre tubing for builders who demand consistent sizing, reliable strength, and professional laminate quality. In addition, every tube undergoes strict dimensional and visual checks before dispatch. Because of this focus on consistency, each tube fits cleanly and performs exactly as expected in structural assemblies and motion systems.

FAQs

When should I choose roll-wrapped over pultruded tubing?
Choose roll-wrapped tubing when your application involves torsion, bending, or mixed loading. For straight push–pull loads, pultruded tubing remains the better option.

Can this tube be drilled or machined?
Yes. Builders can drill and lightly machine the tube; however, careful feed rates and sharp tooling help prevent fibre breakout. Sealing exposed fibres afterward is recommended.
