Method of making fluorocarbon coated braided hose assemblies

摘要

A method of making a lightweight hose assembly (10) of the type adapted for carrying fuels and other corrosive fluids. The method includes the steps of applying a dispersion containing a fluorocarbon polymer material to an inner tubular liner (12), also of a fluorocarbon material, and positioning a braided layer (13), eg of glass fibers, about the exterior of the liner (12). The inner tubular liner (12) and braided layer (13) are then subjected to a second dispersion including a fluorocarbon polymer material. The first and second dispersions may include a surfactant for a more even distribution of the dispersion throughout the braided layer and about the inner tubular liner, and a carrying agent. Subsequently, the assembly (10) may be heated to remove the carrying agent and surfactant therefrom. The assembly (10) can then be sintered to cure the fluorocarbon polymer material into a coating (14) dispersed throughout the braided layer (13) and about the inner liner (12).
