Carbon Fiber Telescoping Tubes (CFRP Telescopic Tube) — Ultra‑Light · Multi‑Section Nesting · Instant Lock
1. Product Definition
Our carbon fiber telescoping tubes are multi‑section hollow rods made from T700/T800 prepreg with a 3K twill or UD black outer layer, cured in an autoclave or via wrap‑pultrusion taper‑fit processes. Each segment extends 0.3–2 m, with total reach up to 12 m and collapse to just 1/5–1/7 of its length—solving carry, storage, and transport challenges for outdoor, industrial, medical, and photographic uses.
2. Core Advantages
- Ultra-Light: 1.55 g/cm³ density—60–70 % lighter than aluminum poles
- High Rigidity: 140–160 GPa flexural modulus; sag < 1 % on full extension
- Rapid Locking: Internal taper self‑lock plus external cam clamp or quick‑release pin locks in ≤ 1 s
- Corrosion‑Proof: Stable pH 3–11, 1 000 h salt‑fog tested—zero maintenance at sea
- Wide Temperature Range: −40 °C to +180 °C continuous; instant 200 °C tolerance
3. Structural Styles
- Taper‑Fit Sections: 0.8–1.5° taper—tightens under extension, zero play
- Straight Sections: 0.08–0.12 mm concentric clearance + spiral lock ring
- Hybrid Design: Base straight tube + tapered top segments for maximum straightness and stiffness

7. FAQ & Remedies
| Issue | Symptom | Cause | Factory Fix | User Check |
|---|---|---|---|---|
| Section Play | Wobble when extended | Taper wear/accumulated tolerances | 0.05 mm tolerance per segment; DLC‑harden taper | Shake; reject if > 2 mm swing |
| Lock Slippage | Slides under load | Oil or resin on taper | Solvent clean; re‑sand taper | Alcohol wipe + retry locking |
| Breakage | Tip fracture | Impact or overload | 0.3 mm wall‑thick base; UD reinforcement | Do not exceed 1.5× rated load |
| Jammed Sections | Won’t extend or retract | Dust or moisture ingress | Dry‑lubricant coating; dust seals included | Clean & lubricate monthly |
| Surface Scratches | Abrasion marks | Insufficient packaging | Bubble wrap per section; foam & carton | Inspect; replace if > 20 mm |
