1. Product Overview

Our Carbon Fiber D‑Shaped Tubes are manufactured in a single autoclave molding step from T700/T800 unidirectional prepreg with a 3K twill surface layer. The “D” cross‑section combines curved‑surface bending resistance with a flat back for easy mounting—ideal where airflow or wall‑hugging installation is critical.

Product Customization Process

  1. Requirement Gathering: Customer submits application scenario, load conditions, dimensions, material specs and drawings.
  2. Technical Evaluation: Our engineers assess feasibility, select fiber grade, resin system, manufacturing method and estimate cost.
  3. 3D Design & Simulation: Create CAD model from client drawings and perform FEA for strength and weight optimization.
  4. Rapid Prototyping: Deliver prototype within 3–7 days, including pultrusion/filament winding and necessary CNC machining.
  5. Sample Validation: Client inspects prototype dimensions, appearance and performance, then provides feedback.
  6. Tooling/Fixture Confirmation: Modify and approve molds or fixtures based on prototype, finalizing production setup.
  7. Pilot Production: Conduct pilot run to verify process stability and re-test performance.
  8. Mass Production: Proceed with full-scale manufacturing according to approved specs and quantities.
  9. Quality Inspection: Perform 100% visual, dimensional checks and ultrasonic NDT; issue inspection reports and material certificates.
  10. Packaging & Shipment: Pack per client’s requirements (bubble-wrap, reinforced cartons or crates) and arrange international shipment.
  11. After-sales Support: Offer installation guidance, maintenance advice and secondary processing services.
