Product overview

GBTECH 18×16×1000 mm carbon fiber tube is a round T300 composite member with a 1 mm nominal wall and a matte twill surface appearance. The 1000 mm format supplies one uninterrupted metre for longer members or cut-to-size production. It is useful when the designer needs freedom to establish the final component lengths after a prototype or nesting review.

The 18 mm outside profile is the largest tube diameter in this listed range. Its 16 mm bore supports evaluation of larger inserts and internal passages, while the 1 mm nominal wall requires careful local connection design.

Product specifications

Long members and cut-to-size stock

Choose this length for long continuous components or several shorter pieces, allowing for saw kerf and end finishing.

Potential uses to evaluate include larger equipment-frame prototypes, cable-routing members, rig and fixture supports. These are design directions, not certified load-bearing applications.

Connection and processing notes

• Confirm the actual 16 mm bore clearance before choosing fittings.

• Use reinforcement or load-spreading interfaces where the joint design requires them.

Use tooling and dust control suitable for carbon-fiber composites. Protect nearby electronics from conductive dust, finish cut edges as required, and validate bonded, clamped or fastened connections before use.

Temperature and design limits

The catalogue lists nominal heat resistance of 150°C. This is not a universal continuous-service temperature: confirm the test method, exposure duration, load and safety margin for the intended duty cycle.

Fiber orientation, resin, unsupported length and joint details determine suitability. Do not infer a certified strength or stiffness value from diameter alone.

Frequently asked questions

Why select 1000 mm? The one-metre format can be reviewed as cutting stock; calculate usable lengths after allowing for kerf, end trimming and finishing.

How is wall thickness calculated? (18 − 16) ÷ 2 gives 1 mm nominal wall thickness; actual dimensional tolerances require confirmation.

Other lengths

Also available in the same diameter family:

• 250 mm length

• 500 mm length
