Fiber-reinforced lined composite pipe, and manufacturing method and device therefor

Abstract

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 lining composite pipe and a manufacturing method and equipment thereof. Background technique [0002] At this stage, my country’s FRP and composite materials industries are facing a new period of development, such as large-scale municipal construction, large-scale railway construction, development of the automobile industry, petrochemical industry, and the country’s policies on energy conservation, emission reduction, and environmental protection during the process of urbanization. The introduction, especially in the municipal and chemical industries, has a 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, aromatic fibers, graphite fibers, etc. were successively developed. These fibers can be ...
