Example Embodiment
[0047] like Figure 1-4As shown, a thermal insulation integrated continuous fiber prepreg tape reinforced composite pipe and a processing method include a foamed thermal insulation pipe 1 and a heat-resistant and pressure-resistant working pipe 2. The plastic outer protective surface layer 1-1 and the foam insulation layer 1-2 are integrally formed. The heat-resistant and pressure-resistant working tube 2 is integrally formed by a plastic inner layer tube 2-2 and an isomorphic structure prepreg reinforcing layer 2-1 that is fused and adhered to the outer wall of the plastic inner layer tube 2-2 by hot-melt winding. The prepreg tape reinforcement layer 2-1 and the foam insulation layer 1-2 are fused together, which improves the pressure and temperature resistance capability and overall rigidity of the working pipeline, as well as the rigidity and waterproofness of the insulation layer.
[0048] The foamed insulation layer 12 is made of hot melt adhesive, AC foaming agent, mixe...
