Abstract

The invention provides a pultrusion pipe. The pipe wall of the pultrusion pipe at least comprises at least one of a circumferential fiber reinforcing layer and an axial fiber reinforcing layer, and a two-dimensional fiber braided layer braided and formed on the outermost layer. At least one layer in the pipe is of a continuous structure in the circumferential direction. The invention further provides a manufacturing method and equipment of the pultrusion pipe. The pipe manufactured through the manufacturing method is braided or wound or arranged layer by layer, and the problems that the numerical content of prepreg is high, a layering phenomenon is likely to happen between the layers in the forming process, and the anti-impact performance is poor do not exist between the layers. At least one layer in the pipe is of the continuous structure in the circumferential direction, no seam or fault exists, and the mechanical performance is excellent and stable. In addition, when the outer layers are wound or arranged, uniform pressure can be formed on the inner layers, interlayer bonding is enhanced, and the problem that the circumferential strength of a traditional pultrusion product is low is effectively solved.

Description

technical field [0001] The invention relates to a pultrusion pipe material, a preparation method and manufacturing equipment thereof. Background technique [0002] Pultrusion molding is a special process in the composite material molding process. The production process can be fully automated, the production efficiency is high, and it has the advantages of high fiber content, excellent and stable mechanical properties, and low energy consumption. However, the traditional pultrusion process makes traditional pultrusion products have defects such as low hoop strength. [0003] In order to solve the above-mentioned strength problems, multi-layer fiber composite pipes are often used, such as rolling and wrapping single-layer fibers in turn to form multi-layer fiber composite pipes. [0004] However, the pipe formed in this way needs to use prepreg material for the coil layer, which is costly, and the numerical content of the prepreg material is high. During the forming process, ...
