Abstract

The invention relates to the field of loose or adhesive fibrous material reinforced high-molecular compounds and particularly relates to a continuous fiber reinforced thermoplastic pipe high-pressureresistant joint pipe fitting group and a manufacturing method thereof. The continuous fiber reinforced thermoplastic pipe high-pressure resistant joint pipe fitting group comprises pipe fittings and connecting pieces, wherein the pipe fittings and connecting pieces are composed of pipes (1); the pipe fitting group is characterized in that the pipes (1) comprise three layers from inside out, namelyan inner pipe layer (11), a reinforcing layer (12) and an outer pipe layer (13) respectively; stepped holes (14) of two-stage steps are formed in two ends of the inner pipe layer (11); larger round holes of the stepped holes (14) are formed in the outer end; smaller round holes of the stepped holes (14) are formed in the inner end. The continuous fiber reinforced thermoplastic pipe high-pressureresistant joint pipe fitting group disclosed by the invention is high in strength, convenient to manufacture and wide in application range.

Description

technical field [0001] The invention relates to the field of reinforcing high-molecular compounds with loose or adhered fibrous materials, in particular to a continuous fiber reinforced thermoplastic pipeline high-pressure-resistant interface pipe fitting set and a manufacturing method thereof. Background technique [0002] Continuous fiber prepreg tape core winding reinforced thermoplastic pipe has the advantages of high pressure resistance, high heat resistance, corrosion resistance, long life performance and large flow rate, light material, light weight, fast installation product characteristics, referred to as high strength, thin wall, corrosion resistance, Long life rigid core tube. The rigid core tube is a fiber reinforced composite tube, and its quality has unique advantages, such as the uniformity of pressure resistance of the ring line and the uniformity of the structure. The - elastic flexibility. [0003] Compared with other metal-reinforced composite pipes such...
