High Modulus Carbon Fiber Tube | Ultra High Strength CFRP Round Pipe Lightweight

Product Specification

High Modulus Carbon Fiber Tube | Ultra High Strength CFRP Round Pipe Lightweight Composite Tubing Custom Size

In precision engineering, structural misalignment, excess weight, and inconsistent tubing quality often delay builds and increase costs. For teams designing UAV frames, robotic arms, or modular equipment, every millimeter of tolerance matters—and metal tubes simply can’t deliver the performance modern systems require.

LIJIN supplies carbon fiber tubes engineered for demanding structural applications. Our tubes offer precise OD and length tolerances, flat mounting surfaces, and superior torsional resistance. We work with UAV manufacturers, industrial automation engineers, and distributors across Europe, North America, and Asia.

Whether you need lightweight framing components, CAD-reviewed custom sizes, or packaging-ready SKUs for distribution, we’re built to support you—quickly, reliably, and with the engineering accuracy you expect.

Why Choose Our Carbon Fiber Materials?

1. High-Performance Indicators: Mechanical Properties Exceeding Industry Standards

• Ultimate Balance of Strength and Weight

Using independently developed PAN-based carbon fiber precursor technology, the product strength reaches above T700 level (tensile strength ≥4900MPa), with a density only 1/5 that of steel, achieving the material characteristics of “as light as aluminum, as strong as steel”. For example, when the company’s carbon fiber plates are applied to the main beams of wind turbine blades, they reduce weight by 30% compared to traditional materials, while increasing fatigue resistance life by 50%.

• Excellent Environmental Resistance

Through high-temperature carbonization treatment (≥1500°C) and surface coating technology, the material maintains stable performance in the temperature range of -196°C to 200°C. Its salt spray corrosion resistance exceeds 1000 hours, meeting the harsh environmental requirements of aerospace, marine engineering, and other fields.

2. Full Industrial Chain Control: Quality Traceability from Raw Materials to Products
