Apparatus for the production of thermoplastic continuous fiber prepreg tape pipes and methods of use thereof

Abstract

The invention relates to the field of a plastic molding composite material containing an enhanced material, in particular to equipment for thermoplastic continuous fiber pre-impregnated belt pipe production and a use method thereof. The equipment for thermoplastic continuous fiber pre-impregnated belt pipe production comprises an extruding machine (1), and is characterized by also comprising a belt winding machine (21), a film winding machine (22), a first traction machine (31), a second traction machine (32), a drying box (4), a vacuum box (5), a marking machine (6), a cutting machine (7) anda material collecting table (8). The use method of the equipment for thermoplastic continuous fiber pre-impregnated belt pipe production is characterized by comprising the following steps for sequential implementation: a, preparation; b, inner layer extrusion; c, pre-impregnated belt winding; d, thermoplastic film winding; e, sizing; f, cooling; g, collection. The pipe quality is high; the raw materials are saved.

Description

technical field [0001] The invention relates to the field of plastic molding composite materials containing reinforcing materials, in particular to a device for producing thermoplastic continuous fiber prepreg tape pipes and a method for using the same. Background technique [0002] Continuous fiber reinforced thermoplastic composite pipe has the advantages of high strength, thin wall, light weight, long life, corrosion resistance, sanitation, environmental protection, green, etc. It is widely used in mountains, reservoirs, river water diversion, urban water supply, central heating, central air conditioning, gas transmission , Crude oil transportation and other pipeline networks, the composite pipe uses wound continuous fibers to bear the stress load inside and outside the pipe, changing the original pipeline from plastic materials or metal materials to bear the stress load inside and outside the pipe, which is a subversion in the pipeline field sexual revolution.

AI Technical Summary

Problems solved by technology

The continuous fiber-reinforced thermoplastic composite pipes produced by the above two processes need lined steel pipes as moulds, which cannot be produced by the continuous method, and the production efficiency is low, the inner layer is difficult to demold and is not smooth, and the air bubbles between the layers are difficult to eliminate, etc.

The Chinese patent with the authorized announcement number 202360912U disclosed "a continuous fiber prepreg tape winding reinforced composite pipe" on August 1, 2012. This composite pipe uses the inner layer plastic pipe as the mold for the winding layer thermoplastic prepreg tape. The prepreg tape is wound while heating, and finally the plastic layer of the surface layer is compounded. The pipes produced by this method, especially the large-diameter pipes, have the disadvantages of large section ellipticity, low interlayer compactness, and high cost of inner and outer plastic thick walls.

[0006] In summary, there are process or product quality problems in the production of continuous fiber-reinforced thermoplastic composite pipes at the current stage of technology
