Abstract
A lightweight hose assembly (10) of the type adapted for conveying fuels and other corrosive fluids is disclosed. The assembly (10) includes a tubular inner liner (12) including a polymeric fluorocarbon material resistant to chemical and heat degradation. A reinforcing layer (14) having gaps extending therethrough is disposed about the inner linear (12). The assembly (10) further includes an outer fluorocarbon coating (16) dispersed throughout the reinforcing layer (14) The hose assembly (10) is characterized by including a metallic reinforcing layer (18) disposed about the reinforcing layer (14) for increasing the strength and bending properties of the hose assembly (10). A method of making the hose assembly (10) includes the step of extruding the inner liner (12), applying a dispersion including a fluorocarbon polymer material and a carrier fluid over the inner liner (12), disposing a first braided reinforcing layer (14) about the inner liner (12) and over the applied dispersion, applying a second dispersion including a fluorocarbon polymer material in a carrier fluid over the reinforcing layer (14) to chemically bond the reinforcing layer (14) to the inner layer (12) and the first applied dispersion. A metallic braided reinforcing layer (18) is then applied about the first braided reinforcing layer (14).
