Abstract
The invention provides a fiber reinforced plastic pipe. The fiber reinforced plastic pipe comprises a fiber reinforced plastic pipe body, an insulated heat preserving layer, and a reinforced protective layer from inside to outside. The fiber reinforced plastic pipe body, the insulated heat preserving layer, and the reinforced protective layer are adhered through the solidification of resin. The insulated protective layer is formed by splicing an inner panel, an outer panel and a hollow structure in an adhesion mode. The hollow structure comprises a plurality of glass fiber sleeves which are arrayed in a parallel mode and are soaked by PVDF. The reinforcing layer is formed by solidifying a carbon fiber three-dimensional textile fabric with suturing lines and resin through an RTM forming method. The carbon fiber three-dimensional textile fabric comprises a plurality of layers of carbon fiber plain cloth and the suturing lines passing through the carbon fiber plain cloth. The fiber reinforced plastic pipe is improved in compressive strength, avoids layering phenomena, and is prolonged in service life and reduced in weight.
