Carbon Fiber Tube Connectors: Clamps, Sleeves, Joints, and Assembly
OEMs building structural assemblies from carbon fiber tubes need to select connector types based on the tube cross-section geometry, wall thickness, joint load direction, and whether the connection must be removable or permanent. The connector type determines how load transfers between tubes at the joint, and a mismatch between clamp geometry and tube OD tolerance can crush thin tube walls or allow slip under load. Xinbo Composites manufactures carbon fiber tubes and supplies assembled tube systems from its Shenzhen facility, including tubes with bonded metal inserts, integrated clamp fittings, and telescoping connector systems. This article covers the four main connector approaches used in carbon fiber tube assemblies and what to specify when ordering. Carbon Fiber Tube Connectors and Mechanical Clamp Types OEMs use three categories of mechanical carbon fiber tube connectors: OD clamps applied around the tube outer diameter, insert connectors bonded or press-fit into the tube bo...
