Embodiment Construction
[0038] Such as Figure 4 Shown, is the flow chart of the manufacturing method of the fiber-reinforced lining composite pipe provided by the present invention, by Figure 4 As can be seen, the method of the present invention comprises the steps:
[0039] Continuous winding of the strip to form liners of increasing length;
[0040] When forming a liner with increasing length, the liner is used as an internal support, and the fiber reinforced material is synchronously wound outside the liner to form a reinforcement layer on the outer surface of the liner;
[0041] While forming a reinforced layer on the outer surface of the lined pipe, the protective decorative material is synchronously wound outside the reinforced layer, so as to form a protective decorative layer on the outer surface of the reinforced layer, so that the lined pipe can be processed into a composite pipe;
[0042] After the composite pipe is formed, post-processing is carried out on the composite pipe so as to ...

The invention discloses a manufacturing method for a fiber-reinforced lined composite pipe. The manufacturing method comprises the following steps that a lined pipe of which the length is increased continuously is manufactured; the lined pipe is used as an internal supporting body, and a fiber-reinforced materials winds the lined pipe to form a reinforcement layer; when the reinforcement layer is formed on the outer surface of the lined pipe, a protective decoration material winds the reinforcement layer to form a protective decoration layer, so that the lined pipe is processed into a composite pipe; and postprocessing is conducted on the composite pipe to manufacture the fiber-reinforced lined composite pipe meeting the requirement. According to the manufacturing method, the fiber-reinforced lined composite pipe is produced through continuous winding and forming, the degree of automation during the whole production process is high, the manufacturing processes are less, the production efficiency is high, the production cost is low, the product quality is high, and large-caliber and mid-high-pressure composite pipes can be produced; and besides, the invention further provides a manufacturing device and the fiber-reinforced lined composite pipe manufactured according to the manufacturing method.
Description
technical field [0001] The invention relates to the technical field of composite pipes, in particular to a fiber-reinforced inner-lined composite pipe and its manufacturing method and equipment. Background technique [0002] At this stage, my country's FRP and composite material industries are facing a new period of great development, such as large-scale municipal construction, large-scale railway construction, automobile industry, petrochemical industry development in the process of urbanization, and national policies on energy conservation, emission reduction, and environmental protection. Introduced, especially in municipal, chemical and other industries, there is broad and huge development space for composite materials. [0003] In the 1940s, due to the needs of the aviation industry, glass fiber reinforced materials were developed. After the 1950s, carbon fibers, mineral fibers, aramid fibers, graphite fibers, etc. were successively developed. These fibers can be combine...
