Lightweight FRP water conveying pipe and processing technology thereof

Abstract

The invention discloses a lightweight FRP water delivery pipe and a processing technology thereof.The water delivery pipe comprises a water delivery straight pipe and a water delivery bent pipe, the water delivery straight pipe and the water delivery bent pipe are connected through an FRP flange or an FRP hoop, and the water delivery straight pipe and the water delivery bent pipe are both formed by winding resin pre-impregnated fiber reinforced composite material winding wires; a plurality of buffering mechanisms are arranged on the water conveying straight pipe in an array mode and detachably connected to the pipeline. The processing technology comprises the following steps: winding by taking steel as a core mold, and taking out the component core mold after the resin pre-impregnated fiber reinforced composite material is cured and formed; and assembling. The resin pre-impregnated fiber reinforced composite material winding wires are integrally formed for multiple times, the interface performance between winding layers at different angles is greatly improved, the overall synergistic effect of water delivery is improved, and the bending rigidity of the water delivery pipe is remarkably enhanced.

Description

technical field [0001] The invention belongs to the field of composite material structures, in particular to a lightweight FRP water delivery pipe and a processing technology thereof. Background technique [0002] Due to its unique forming process and obvious anisotropy characteristics, pultruded profiles make their lateral force performance weak. Under external loads, local buckling or splitting damage is easy to occur along the pultrusion direction, so that composite materials cannot be fully utilized. Strength of. Due to its unique molding process and obvious anisotropy characteristics, the fiber reinforced composite material winding pipe greatly reduces the weight compared with the traditional iron water delivery components, and the fiber reinforced composite material winding pipe can withstand more than traditional plastic-coated hoses. water pressure. Filament winding molding process is used to prepare water conveying components. Most of the existing FRP water convey...

AI Technical Summary

Problems solved by technology

Filament winding molding process is used to prepare water conveying components. Most of the existing FRP water conveying elbows use the same winding angle, which has poor synergy under hydrodynamic loads; At the same time, the water delivery pipe is directly placed in the water tank or the pipeline. During the water delivery process, the water delivery pipe is subjected to strong vibration, resulting in a short service life of the pipe body.
