High-toughness lightweight carbon fiber composite pipe

Abstract

The utility model discloses a kind of high-toughness lightweight carbon fiber composite pipes, including coaxially arranged outer tube and inner tube, the inner wall of outer tube is provided with convex ridge extending along its axial direction, the outer wall of inner tube has the insertion slot of convex ridge insertion cooperation, the inner wall of inner tube is provided with support ring around its axial line circumferentially.The setting of convex ridge can improve the structural strength and rigidity of composite pipe, and stress is dispersed along the axial direction, effectively inhibit the occurrence of composite pipe bending phenomenon, maintain the straightness of composite pipe, improve its as film pressing roller film pressing effect;The setting of support ring can provide uniform radial support force, effectively inhibit the occurrence of composite pipe ovalization phenomenon, maintain the circular cross section of composite pipe, further improve its as film pressing roller film pressing effect.
