Problems solved by technology

However, to form a convex structure on the inner surface of the shell, the surface of the mandrel used will also have a corresponding concave-convex structure, so that the concave-convex structure on the surface of the mandrel can be transferred to the inner surface of the shell, but such a manufacturing method will make it difficult to separate the shell from the mandrel after forming
[0004] Furthermore, the fiber thread must form a certain angle (not 0 degrees) with the mandrel to be wound on the mandrel, so the fiber thread cannot be arranged along the axial direction of the mandrel, which is still insufficient for strengthening the axial stiffness

Abstract

Provided is a composite tube used for a support structure. The tube comprises an inner tube body with a concave-convex inner surface and a housing wrapped on the outer surface of the inner tube body. The housing comprises a fiber structural layer which is formed by winding, with a fiber yarn as a main body. Through the composite tube used for the support structure, a problem of removing a mandrel is solved. The composite tube is easy to manufacture, and saves cost.

Description

technical field [0001] The invention relates to a pipe used for supporting structures, in particular to a composite pipe used for supporting structures and a manufacturing method thereof. Background technique [0002] The support structures used in general buildings are usually made of metal materials, but the metal materials have the disadvantages of easy corrosion and high unit volume weight. Therefore, some alternative materials have been gradually developed. For example, U.S. Patent No. 6,189,286 discloses a fiber-reinforced composite structural member, which includes a shell formed by polymers and fibers embedded in the polymers and a shell made of The concrete core formed by the cured concrete within the shell can have the advantage of being lightweight and less prone to corrosion. The shell is mainly wound from a fiber thread, which is made by first attaching the fiber thread with a polymer binder, and then winding the fiber thread on a mandrel and intersecting one o...
