Pipe special for manufacturing continuous fiber reinforced thermoplastic pipe fitting, and manufacturing method thereof

Abstract

The invention relates to the field of reinforcing high-molecular compounds through loose or adherent fibrous materials, in particular to a pipe special for manufacturing a continuous fiber reinforcedthermoplastic pipe fitting, and a manufacturing method thereof. The pipe special for manufacturing the continuous fiber reinforced thermoplastic pipe fitting is characterized in that a continuous fiber reinforced thermoplastic pipe fitting pipe (1) is an interlayer hot-melting combined special three-layer structure continuous fiber reinforced composite pipe which is composed of a particularly thickened pure plastic inner layer pipe (11), a reinforced core layer pipe (12) with the particularly-increased continuous fiber prepreg tape winding layer number and a pure plastic protective layer outerlayer pipe (13). The pipe special for manufacturing the continuous fiber reinforced thermoplastic pipe fitting is convenient to manufacture, high in mechanical strength and long in service life.

Description

technical field [0001] The invention relates to the field of reinforcing polymer compounds with loose or adhered fibrous materials, in particular to a special pipe for making continuous fiber reinforced thermoplastic pipe fittings and a manufacturing method thereof. Background technique [0002] Traditionally, plastic pipe fittings are basically made of direct, elbow, tee and other pipe fittings through mold injection molding machine injection molding, and some pipe fittings for large-diameter cold water pipes are made by bevel cutting plastic pipe end-to-face joint process. The above process The manufactured pipe fittings can only be used in low-grade pressure piping systems under the conditions of 1.6MPa and 70°C. [0003] In my country, long-distance transportation, high-mountain water diversion and other water supply pipelines, industrial mineral transportation pipelines, and long-distance oil and gas pipelines are in great demand for 2.0MPa-30MPa high-pressure and ultra...

Problems solved by technology

[0003] In my country, long-distance transportation, high-mountain water diversion and other water supply pipelines, industrial mineral transportation pipelines, and long-distance oil and gas pipelines are in great demand for 2.0MPa-30MPa high-pressure and ultra-high-pressure pipeline systems. Requirements for withstand voltage and high withstand voltage

[0004] The pipe made of thermoplastic continuous fiber prepreg tape is wound and reinforced. It has the characteristics of withstanding high pressure above 30MPa, operating temperature of 130°C, and service life of more than 80 years. It can be widely used in water supply pipelines such as long-distance transportation, high mountain water diversion, and industrial mineral transportation pipelines. , Long-distance oil and gas pipelines, due to the manufacturing process, thermoplastic continuous fiber prepreg tapes cannot be made into pipe fittings that satisfy high pressure resistance, high heat resistance, and long life through traditional injection molding and end-to-face joining methods, so far it has not been possible to achieve non-woven fabrics. A breakthrough in metal pipe fittings and interface technology
